(PhysOrg.com) -- 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. A notebook computer thus usually runs only about two hours. The reason for this is the relatively small capacity of the graphite anode in these batteries to absorb lithium ions. http://www.physorg.com/news146320050.html Chemistry Wed, 19 Nov 2008 12:27:30 EST news146320050
