Huawei reveals rapid charge batteries: 50% capacity charged in minutes

November 16, 2015 // By Paul Buckley
Watt Lab, which belongs to the Central Research Institute at Huawei Technology Corporation Limited, has unveiled protoype quick charging lithium-ion batteries that claim they can be charged 10 times faster than current batteries, reaching approximately 50% capacity in mere minutes.

The batteries were revealed at the 56th Battery Symposium in Japan where Huawei presented videos of the two types of quick charging lithium-ion batteries: one battery with a 600 mAh capacity that can be charged to 68% capacity in two minutes; and another with a 3000 mAh capacity and an energy density above 620 Wh/L, which can be charged to 48% capacity in five minutes to allow ten hours of phone call on Huawei mobile phones. The quick charging batteries underwent many rounds of testing, and have been certified by Huawei's terminal test department.

According to Chinese smartphone maker Huawei, the company bonded heteroatoms to the molecule of graphite in anode, which could be a catalyst for the capture and transmission of lithium through carbon bonds. Huawei stated that the heteroatoms increase the charging speed of batteries without decreasing energy density or battery life.

Huawei claims that the technology will revolutionize electronic devices, especially with regard to mobile phones, electric vehicles, wearable devices, and mobile power supplies.
