Huawei Technology Corp., a provider of electronics for mobile phones, mobile broadband devices and home devices, has recently announced that its Watt Lab developed a next-generation quick charging technology.
Watt Lab, which belongs to the Central Research Institute at Huawei Technology Corporation Limited, has developed batteries that have achieved charging speeds 10 times faster than normal batteries, reaching about 50% capacity in minutes.
Huawei created two kinds of quick charging lithium-ion batteries: a battery with a 600 mAh capacity that can be charged to 68% capacity in two minutes and another with a 3000 mAh capacity and energy density above 620 Wh/L, which can be charged to 48% capacity in five minutes to allow 10 hours of phone call on Huawei cellphones. These quick charging batteries underwent many rounds of testing, and have been certified by Huawei's terminal test department.
How They Made Them
According to the company, the Watt Lab team bonded heteroatoms to the molecule of graphite in anode, which could be a catalyst for the capture and transmission of lithium through carbon bonds. These heteroatoms increased the charging speed of the batteries without decreasing energy density or battery life.
Huawei is optimistic that its breakthrough in quick charging batteries will lead to a new revolution in electronic devices, especially with regard to mobile phones, electric vehicles, wearable devices and mobile power supplies. The company believes that the battery breakthrough will allow people to charge device batteries in the time it takes to get a cup of coffee.
Huawei's Watt Lab works closely with industry partners to promote technological development. It focuses specifically on technical development of energy storage to support a better connected world via sufficient energy.
