Huawei has unveiled a range of quick charging lithium-ion batteries that have achieved a charging speed 10 times faster than that of normal batteries, reaching around 50% capacity in minutes.
Two demonstrations were shown at the 56th Battery Symposium in Japan showing two types of quick-charging li-ion batteries: one with a 600mAh capacity was shown to charge to 68% capacity in two minutes; and another with a 3000mAh capacity and an energy density above 620Wh/L, was shown to charge to 48% capacity in five minutes. These quick charging batteries are claimed to have undergone many rounds of testing, and have been certified by Huawei’s terminal test department.
According to 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 says that these quick charging batteries will lead to a revolution in electronic devices, especially mobile phones, electric vehicles, wearable devices, and mobile power supplies.
