Canadian fuel cell-driven development of yeast

According to the United Kingdom, "New Scientist" magazine reported that scientists have recently said that people of blood glucose for energy in the yeast cells that one day people will be driven into the body of the electronic devices, such as pacemakers. This vivid self-generated power in order to replace the regular replacement of laptop battery of conventional surgery. Since the University of British Columbia, Canada will be a team of scientists at yeast encapsulation in soft capsules, has been developed to such a micro fuel cell micro-organisms, can be applied to the treatment of paralysis of the spine such as electron micro-electrode devices. Engaged in this yeast to develop fuel cell scientists, said spine microelectrodes implanted in the spine necessary and therefore very difficult to replace batteries VGP BPS8 , VGP BPS9 , VGP BPS9/B , VGP BPS9A.To rely on traditional high-temperature fuel cell catalysts such as platinum to electron spin-off from the fuel, resulting in current. Microbial fuel cell which uses living cells in the low-temperature catalysts - enzymes to generate a current. The simplest approach is that, when the cells began to break down food, on the direct "steal" of the electron generated by cells. This approach is in the "e-intermediary" to help achieve the so-called "e-intermediary" is small enough chemicals through the cell to obtain electron,Sony battery and then can run out from the cells. The new fuel cell component from Saccharomyces cerevisiae, the yeast sealed by poly dimethyl siloxane (PDMS) material in the capsule, together constitute the fuel cell. Scientists currently developed fuel cells that are micron-size samples, and an area of 15 square microns, 1.4 microns thick. The results of this study published in the latest issue of "Journal of Microelectronic Systems" on. Methylene blue compound used in dyeing of biological samples VGP BPS9A/B , VGP BPL9 , VGP BPS10 ,Today, University of British Columbia, Canadian scientists will be used for "e-intermediary." When yeast break down glucose, the methylene blue from the yeast cells where the "theft" of electronics, VGP BPS3 , VGP BPS5 , PCGA BP2NY electronic delivery of this will be followed by the other side of yeast cells, resulting in a weak current. Up at the cathode, from yeast cells combine hydrogen and oxygen ions produced water. To increase the size of the electrode to increase the fuel cell power output, the group using silicon etching techniques to create "mini-poles", which covers an area of about 40 square micron, 8 microns high. Tested, the yeast can produce fuel-cell around 40 nava electricity, compared to quartz watches generally can produce electron micro-watt power class. Therefore, if the use of the energy storage capacitors, toshiba battery and the yeast will be able to drive a number of fuel cell devices. This will be carried out yeast genetically modified so that it will have greater power output capability. However, this goal faces many challenges. For instance, let the healthy growth of yeast cells, toshiba PA3383U-1BRS,toshiba PA3384U-1BRS and its waste cases no damage was cleaned up, so that excretion of harmful substances to human blood.

EU awarded instruction for new laptop battery

\It said that EU awarded instruction for new dell battery ,which directive forced apple iPhone to change the design
October 8 message, the EU is considering requiring all the cell phone must be able to be easily replaced. This requirement may cause the problem Apple iPhone mobile phone.
AppleInsider website found that UK trade publication The new electronic on an article published in the European Union is considering the introduction of the computer industry about a number of laws and regulations. A few years ago with the enforcement of RoHS (Reduction of Hazardous Substances) directive requires a computer industry in the production HP battery , Compaq battery process to eliminate the harmful chemical substances and / or hazardous materials,the European Union is considering taking on a new directive.
New directive will require manufacturers to ensure that they can easily replace the battery, or by sliding the Apple battery cover or by warehouse to unload some screws can be replaced. Of course, iPhone and iPod do not fit this requirement. Apple requires users to put iPhone and Apple iPod battery replacement. The battery of these products are in the main circuit board of the following.
At present, these instructions are rather vague, unclear whether the iPhone caused a major change in design. As AppleInsider website pointed out, this directive is to prevent mind into the wild. If Apple can to the EU that its IBM battery , Toshiba battery replacement program be able to prevent this result, Apple may be able to meet the requirements of EU Directive.
However, according to the new electronic reported that the proposed Directive does require the to ensure that the design can easily be replaced.
Today's best selling laptop batteries are: sony battery , PCGA-BP2NX , PCGA-BP2S , PCGA-BP2T , PCGA-BP51 .

Lithium-ion laptop battery , in 2009 achieve a leap (b): requirement varies by vehicle

Lighter than nickel-hydrogen batteries 1 / 2 Lithium-ion rechargeable battery the advantages of easy to say that is the weight, volume of only nickel-metal hydride (Ni-MH) rechargeable batteries dell battery , Latitude D620 battery , Latitude D820 battery can achieve about half of the same performance. Battery performance in general to unit weight of energy and power to express, lithium-ion rechargeable battery unit weight of the energy density (the density in particular related to the EV travel distance) and power density (related to the HEV of the ease of charging and discharging) are nickel Hydrogen 2 times.
Sanyo Electric said that the development of batteries for the Audi, and its power density and energy density of nickel-metal hydride has reached 2.3 times. Same, AESC's batteries have reached about 2 times, from the point of view of volume, it is estimated to reach about 2.3 times.
R & D in the current HEV, EV, PHEV three electric vehicles, the recognized are the closest practical level of HEV. System has been used in nickel-hydrogen recedent to Prius as an example the use of the HP battery capacity is only about 1.3kWh.
On the other hand, EV and PHEV prototype car has also finally debut. EV at the field, the real production car will be iMiEV and Plugin Stella Concept of production constitutes the performance target. At this point even if the capacity are light vehicles of iMiEV, also required Prius 12.3 times 16kWh.
Mitsubishi iMiEV At bottom, under a number of configurations. Capacity of 16kWh, voltage of 3.7V, with a capacity of 88 units 50Ah battery.
EV Energy all drivers want to rely on batteries, and therefore more stringent requirements of the Apple battery . Compared with the HEV battery status is usually (SOC) of 50% as the center, the scope of work of the at its upper and lower 10%, EV's use of greatly expanding the scope of the need.
However, CO2 (carbon dioxide) emissions from the perspective of consumers, EV more advantages than the HEV. Click on the basis of projections Sanyo , HEV mode at 10.15 the CO2 emissions 123g/km, while the EV for 49g/km, the former can be reduced to 1 / 2 below.
PHEV can be equipped with more than HEV batteries Apple A1078 , Apple A1008 , Apple A1079 , to extend the driving distance between the requirements for the HEV batteries with batteries and battery between EV. Nissan EV from the development experience, EV driving power required by the vehicle weight of 1.7t at level 150 ~ 250Wh/km. If you are 1.3kWh the Prius, use about 20% of the SOC, the farthest we can only travel less than 2km.
And the PHEV Prius prototype vehicles through the nickel-metal hydride rechargeable IBM battery and in parallel double the size of obtained 2.6kWh capacity, will be extending the use of the SOC to 20 ~ 80%, so that battery-powered driving distance reach 13km. If its replaced by lithium-ion rechargeable batteries IBM ThinkPad T43 , IBM ThinkPad T41 , IBM ThinkPad T40P , Ni-MH rechargeable only half the weight, you can achieve the same performance PHEV.
HEV and EV require different characteristics of The characteristics of the in HEV, EV, PHEV three cars on what are the differences? Data to Toshiba as an example, the company developed for HEV batteries, the power density reached 3800W/kg, belong to high-power attention to type. Even though at supporting and accelerating the renewable electricity requirements with respect to accessibility of HEV high current flow through a short period of time, but not because of the battery-powered Long time traveling, so belong to a lower energy density level.
Toshiba's performance and strive to achieve. HEV battery connection at a power density of the development of 3800W/kg products. At PHEV batteries Toshiba battery are being developed with a capacity of 10Ah and 20Ah products. The EV Acer battery objectives are to achieve energy density 150Wh/kg.
The EV is just the opposite. Although 100Wh/kg required more than high energy density, but not so high power density requirements. The PHEV performance target is between the range of HEV and EV. To Toshiba's PHEV as an example, the company's goal is to achieve power density 1300W/kg, the energy density of 120Wh/kg.

Some experience for using laptop batteries

We may always ask this question,when I use AC adapter I should not use sony battery . Batteries are not put together do not have to extend the battery life can it? Battery life in the end how much? Li-ion Acer battery memory effect did not it? IBM to do so long for this one slowly accumulated experience, come up with to share with everyone, everyone has to mention Oh mistake. . . . First, lithium are memory effect is very small, almost to 0. Two, then the laptop battery can be are not the direct use of AC do? Not Three, the reasons for which are lithium-ion at a relatively long period of time if the static state (the so-called relatively static, that is, without electricity or a small number of battery electric time. Long time how long we are: six months or so), will completely lose the stored energy of the function (no matter what method you use, such as the so-called mesenchymal Dafang large, and even do not charge more than 12 hours use) Four, if the is trying to put together if not, it should be filled up to 90% of the electricity, plastic wrap on a cool, dry place Friday,Toshiba battery life in the end how much? Tell everyone, there is no concept of time constraints, an 8-cell lithium-IBM battery life (remember that is the life) is about 800-1200 charge, below this figure there is certainly the quality of the problem Six, we know how to us the number of electric charge it? To give an example, IBM's ACCESS IBM has an inside view of the use of the number of batteries, we can clearly know that the first charge time and state of health. Other books should also have such similar features, look everyone. Seven, up from the root extends life (that is, life), is absolutely no need to put on the Apple battery had to come from the NB! I have a good idea, everyone can try. If you have AC around the time at boot every day even before the first AC on NB, to ensure that the battery of the lights after the boot! Keep this in mind! So, we are slightly battery charge current, the power to protect the main board will not let the machine have any questions! At this point the situation in a non-rechargeable batteries Compaq battery , HP battery , dell battery are the number of! A year down the battery only charge you 50 times and six hundred times which do you prefer?

Widespread use of portable equipment, and promoted

Widespread use of portable equipment, and promoted the rechargeable laptop battery market and the battery industry. Portable equipment to increase run-time, mobile phone call requests for extension of time, which requires to increase the energy density of chemical batteries. Be able to meet these technical requirements are lithium ion and lithium polymer batteries. Sony's first production in 1990, a rechargeable lithium-ion , lithium-ion sony battery has been used in notebook computers and mobile phones, the future may also be used in digital telephone. Lithium polymer batteries VGP-BPS2 ,VGP-BPS3 , PCGA-BP71 , VGP-BPS5 are also a new generation of batteries, large quantities in 1999 to enter the market. In addition to lithium polymer batteries are solid polymer electrolyte instead of liquid electrolyte, the other with the lithium-ion is basically the same. Polymer electrolyte material is formed by the melting of the general body film, the main body in the dissolved polymer such as polyethylene oxide as a solvent for non-mobile. The benefits of lithium polymer batteries are made of any shape and can be relatively light, this is because it does not contain heavy metals and do not have to maintain electrolyte leakage of the plastic case. They have better performance, the ideal state lithium polymer capacity of thousands of mA / h, and more security. Solid-state electrolyte such as a sealed gel, in charge of natural process will not easily disintegrated. Lithium polymer batteries and lithium-ion dell battery technology can replace the battery NiGd. But the price is too high, the market has not fully accepted, especially lithium polymer technology. Darnell Group analysts think Brush: polymer batteries will not be expensive than the lithium-ion , the current production is indeed a lot of expensive, which promoted the lithium-ion battery technology. Previously for the lithium-ion laptop batteries are the cost of 41.42 U.S. dollars, the polymer used in laptop batteries are the cost of 60.80 U.S. dollars. Anyone who does not believe that lithium-ion batteries are cheaper than the polymer one of the advantages of batteries. Some HP battery manufacturers are turning to the lithium polymer battery technology, Toshiba America Electronic Components Inc. (TAEC) has invested heavily in this area. Lithium polymer lithium-ion are shifted because of the Japanese market needs and lithium-ion has become very cheap. Price change and increase productivity and earnings are not necessarily the same. TAEC think, lithium polymer batteries are tight, and it is the possession of the goal 3 ~ 6mm thick battery market. Will enhance production capacity, from the current 1.5 million to improve in 2001 to 1,000,000 2. And as new technologies are developed, prices will fall. Some people in the trade that in 5 years, lithium-ion batteries and lithium polymer batteries will be a small price gap. Face the future application of the market, many people naturally from small portable devices and mobile phones turned to other areas of application of the Pavilion ZD7000 . The largest market is the automotive application.
At this stage, the Apple battery industry who are optimistic about the enormous profits of the automobile market, the implementation of stringent environmental protection measures and feasible energy requirements and the electronic hybrid vehicles are not development, lithium polymer have a wide application prospect. A referred to as the "T" and with 14-inch screen and remote control of the processor to connect to another belt and wrist at the computer, the mobile hospital system and comply with the Wireless Application Protocol phone can be on the Internet (figure and there is sound) All these applications are required to charge and store energy, and the smallest space. Prediction Polymer is expected to this year's shipment volume reached 19 million, 1.4 million last year. Conservative freight is expected to 3.25 million per month in the first quarter of 2001 shipment volume of production capacity is 2 times. Analysts think: to other products based on lithium polymer in the battery of the total share of income will increase, for instance, Brush said: NiCd batteries because sales fell, lithium polymer batteries to 2003 or 2004 market share NiCd batteries will be over. Rechargeable IBM battery market from last year's approximately 4.4 billion U.S. dollars in 2004 rose to 5.8 billion U.S. dollars, the total annual revenue growth rate of 5.5%. According to Kline & Company in "the world's advanced battery technology opportunities from 1997 to 2007" report, its conclusions more specific, and is projected to 2007, the annual market demand for lithium polymer batteries for at least one billion U.S. dollars. 50% of these demands from the United States and Western Europe. No matter how the actual production, the application in the mobile phone lithium polymer batteries IBM ThinkPad T40 ,IBM ThinkPad X60 ,IBM ThinkPad R60 ,IBM ThinkPad R40 are the biggest growth. Light and easy to use lithium-ion battery than its more popular and more competitive, with the development and application of new technologies, the price will eventually come down. Product Development Matsushita Battery Industrial Company in May 2001 at the beginning of mass production of large-capacity lithium polymer battery, a capacity of 1650mA / h, the negative terminal of the are manufactured using new materials. Toshiba's OEM battery group also issued a personal digital assistant for the 2.5mm-thick series of lithium polymer batteries, the company said: The use of the structure of products using a new cathode material and the structure and capacity of the existing capacity of 1.7 ~ 3.3 times (now the largest capacity of 1000mA / h), mass-produced products, in May 2001 before the 500,000 per month to the end of next year one million per month 1. TAEC is to provide a new design over the existing design of the advanced lithium polymer, in particular, are suitable for operating temperature range. Electrochem capacity has developed at 35 ~ 6500mA / h, thickness 0.65 ~ 6.3mm at a variety of Toshiba battery capacity. PolySter company plans to launch at this time of 1200mA / h battery, specifications for the 46? 50? 6mm, used in BP and personal digital devices, the capacity of 1000mA / h battery for mobile phone; 850mA / h battery for the Web -access, 310Ma / h batteries for wrist instruments; 160mA / h (30? 29? 3.2mm) for earphone. Ultralife Batteries Inc. has recently announced the completion of a production line, the production of thick 0.5mm, thickness 4.4mm after packaging capacity of 700mA / h, the weight of about 20g of the battery. Other lithium-polymer battery technology is in various stages of development or near the production stage, such as Lithium Technologies, Inc., aim for the automotive market are the 9A / h, the specifications for the 4? 8? 0.25 inches of the battery. Commercial activity Valeme technology company in accordance with the protocol obtained from Telcordia Technologies, Inc. common stock Valeme of 3 million newly issued shares at the 12 month protocol implementation, and the United States, including 42 patents, 15 the existing business license, and PLON (TM) trademark.
