New battery tech gives 10 hours of talk time after only 5 minutes on charge

Researchers at the Huawei Technology Corporation have unveiled a new quick charging lithium-ion battery. The development is said to result in batteries that charge ten times faster than conventional Li-ion batteries.

At the 56th Battery Symposium in Japan last week, Huawei, which provides batteries for many devices from other manufacturers as well as their own, showed two videos depicting fast charging with the new batteries. In one, a small 600 mAh capacity battery charged to 68 percent capacity in two minutes. In another, a much larger 3,000 mAh battery charged to 48 percent capacity in five minutes. The latter battery has an energy density of 620 Wh/L and is reported capable of powering a Huawei mobile phone for 10 hours of continuous talk time with that 48 percent charge.
