Sony Develops New High Power Rechargeable Battery
Sony says that it has launched a new type of lithium ion secondary battery that combines high-power and long-life performance, using olivine-type lithium iron phosphate as the cathode material. The Olivine-type lithium iron phosphate used in this new battery is suited for use as a cathode material due to its robust crystal structure and stable performance, even at high temperatures. more
Research team reports major breakthrough in lithium battery technology
An NSERC-funded lab at the University Of Waterloo has laid the groundwork for a lithium battery that can store and deliver more than three times the power of conventional lithium ion batteries. The research team of professor Linda Nazar, graduate student David Xiulei Ji and postdoctoral fellow Kyu Tae Lee are one of the first to demonstrate robust electrochemical performance for a lithium-sulphur battery. The finding is reported in the on-line issue of Nature Materials. more

Air-fuelled Battery Offers 10-Fold Increase in Capacity
..oo, as the new component is made of porous carbon, which is far less expensive than the lithium cobalt oxide it replaces. The research work, funded by the Engineering and Physical Sciences Research Council (EPSRC), is being led by researchers at more
Batteries Need Charging More Often to Cope with Smartphone Power Demands
Studying the battery budget in cellphones, Strategy Analytics' latest report reveals that improvements in component power consumption and battery chemistry will not be sufficient to offset the growth in feature penetration and application usage. This report predicts that web browsing, navigation and social networking will see the biggest increase, growing from a combined 9% of the battery budget in 2008 to 30% by 2014. more

Coming soon: Improved lithium ion batteries?
Rechargeable lithium ion batteries provide portable devices that require a lot of energy, such as mobile telephones, digital cameras, and notebook computers, with power. However, their capacity, and thus the running time of the devices, remain somewhat limited. The reason for this is the relatively small capacity of the graphite anode in these batteries to absorb lithium ions. more
