Huawei Technologies last week unveiled lithium-ion batteries that recharge in minutes rather than hours. The batteries, developed by Huawei's Watt Lab, recharge 10 times faster than their competitors and can reach 50 percent capacity in two to five minutes, the company said.
Huawei demonstrated two models at the 56th Battery Symposium in Japan last week: a 600-mAh unit that reached 68 percent capacity in two minutes and a 3,000-mAh model that reached 48 percent capacity in five minutes. Huawei did not say when the batteries will be ready for prime time, but initial reports suggest it may be some time before the technology begins appearing in smartphones.
While fast charging sounds like a good idea, the technology can have drawbacks such as lower power density, fewer recharge cycles per battery, higher costs due to the specialized hardware and the need for new manufacturing equipment.
Huawei's new batteries address some of those problems and, if and when this technology is fully deployed, it would go a long way to help reducing the battery-life anxiety faced by power users of mobile devices.
