Huawei shows off fast-recharging battery

Huawei has developed a prototype smartphone battery that can be recharged to half its capacity in just five minutes.
The battery is based on the same lithium ion chemistry used in cellphone batteries today but gets its advantage from atoms of graphite bonded to the anode, Huawei said on Friday at an industry conference in Japan.
