“Not included”, batteries have received a new toy, remember these words to your profile package of cold? Grow up, our high-tech “toys” becomes increasingly complex and attractive. But drive their battery principle did not change.
If so?
Intelligent network (Smartgrids), hybrid, renewable energy is popular environmental protection technology, but behind the scenes, the chemist and engineers are committed to cut out the ecological effect. The batteries, Recent hydroxyl oxidation nickel, olivine type enables lithium iron and nickel line, lithium battery chemistry technology to make the breakthrough of digital products up tomorrow history but the problem of alkali/manganese dioxide AA battery.
NiOOH (hydroxyl oxidation nickel or NiOx) battery has been available for several years, but, like the alkaline battery anode system based on nickel to produce higher voltage (1.7 V, alkaline battery for 1.5 V). NiOx batteries commonly used for high power applications (such as a digital camera or portable gaming products), to provide equivalent alkaline batteries twice. But in the remote control, low power consumption, etc NiOx battery life and alkaline batteries.
SONY’s recent first will the technology of lithium ion battery variant commercialization. The technology developed by the U.S. researchers, using phosphoric acid lithium iron type olivine LiFePO4 (anode) as.
SONY’s recent first will the technology of lithium ion battery variant commercialization. The technology developed by the U.S. researchers, using phosphoric acid lithium iron type olivine LiFePO4 (anode) as. SONY will new anode materials with a maximum of decreases resistance can be combined design technology patent particles, 1800W 3.3 kg/V output and power density of rechargeable batteries design, have longevity, in 2000 after filling/discharge wheel remained 80% initial capacity. The battery has rapid charging ability (30 minutes to 99%), and filling in the use of stable discharging voltage.
The battery has been applied in some powerful tool for SONY, and in practical application in positive feedback.
The earliest LiFePO4 patent technology by the university of Texas JohnGoodenough and team in 1996. LiFePO4 for solving the lithium cobalt oxide and lithium manganese oxide lithium ion battery structure, low rate of discharge to the problem of short life cycle was designed.
LiFePO4 is a kind of high stability, scientists believe it can materials used in countless consumption level from mobile phones, and products of rechargeable batteries applied to electric cars etc. Large. XueFoLai (220 Volt listing by core lithium ion battery).
Peridot structure of LiFePO4 let grid than other cell structure deformation more small, bring better discharge process. Therefore the materials circulation of LiFePO4 extremely long life, also shows excellent storage life. It can endure oxidation and acidic environments.
Battery, the battery LiFePO4 safety at 300 ° C to structure of 500 ° C, high temperature stability, still can maintain the highest can withstand 700 ° C. In the extreme temperatures, other lithium battery will cracking even explosions.
The rapid charging LiFePO4, long life significantly to environmental protection. Electric car battery will also gain LiFePO4 by charging more long distance running after launch, hope the Volt products and competitive automobile manufacturers might be interested.
The new nanowires batteries gradually with rapist
Another promising lithium batteries battery is covered with line, line of nano silicon steel positive to replace traditional lithium-ion batteries graphite anode. Silicon can store of lithium ten times more than the graphite, that power density increases. Batteries, increase total quality of surface allowing faster/discharge rate.
Battery anode steel surface covered by the shrinkage/expansion of silicon line output power. Charging process, silicon line of lithium battery atomic absorption, after the expansion, In the process of discharging lithium ion, silicon online sucked the linear contractive, silicon.
Traditional, simple silicon positive study began in thirty years ago. When scientists decided to give up, because this kind of material in silicon to split up when lithium absorption, damaged, positive capacity is too weak to support further study.
Researchers at Stanford university problem is used when judging the shape of silicon.
Now to the method for paper thickness in diameter is a thousandth of nanostructures. Tree The new nanowires absorption volume expansion to normal after the lithium is four times the condition, but the silicon anode won’t break or damage.
The new nanowires cell researchers are looking for a proper anode materials, and silicon anode nets matching filling/discharge capacity, which fully shows the technology in energy storage density of outstanding progress. Stanford university, assistant professor of materials science and engineering YiCui is leadership team, they develop the positive technology that five years later the new nanowires lithium ion rechargeable battery technology can realize the comprehensive commercial.
Above a few technology is just the start of the study, with deep battery to electronic products, players can expect battery life than toy itself life that day.
