Huawei has revealed a new technique for charging batteries that is up to 10 times faster than existing methods.
Huawei bonded heteroatoms to graphite molecules. This can be a catalyst for capturing and transmitting lithium through carbon, which has the effect of increasing charging speeds without decreasing the energy density or overall battery life.
The company demonstrated how it was able to charge a 600mAh to 68% capacity in two minutes, and a 3000mAh battery to 48% in five minutes — enough to power 10 hours of voice calls. “Huawei is confident that this 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,” said the company.
The demonstrations were made at the 56th Battery Symposium in Japan. Many of today’s smartphones rely on Qualcomm’s QuickCharge technology, which is baked into its Snapdragon processors and reduces the time it takes to charge batteries. Qualcomm’s technology is not as fast as what Huawei demonstrated this week.
