At the 56th Battery Symposium in Japan, Huawei showed off its next generation of quick charging batteries. Huh? Yes, there’s a Battery Symposium in Japan, and yes, there have been fifty-five of them in the past. Stay focused here.
Huawei says its new lithium-ion batteries can achieve charging speeds ten times faster than normal batteries.
The company has shared videos of two types of batteries. One has a 600mAh capacity and can reach 68% capacity in two minutes.
The larger battery has a capacity of 3,000mAh. It apparently takes just five minutes to reach 48%.
For comparison, Qualcomm boasts that Quick Charge 3.0 can rejuvenate a battery to a comparable level in closer to half an hour.
As for the science, Huawei says it “bonded heteroatoms to the molecule of graphite in anode, which could be a catalyst for the capture and transmission of lithium through carbon bonds.” This, the company says, increases charging speed without decreasing energy density or battery life.
For now, this is just wow factor. Hopefully we see the technology make its way into smartphones, smartwatches, or something similarly smart soon enough.

Huawei reveals the next generation of quick charging technology
The new batteries can be charged 10 times faster than current batteries, reaching approximately 50% capacity in mere minutes
[Nagoya, Japan, Nov.13, 2015] Watt Lab, which belongs to the Central Research Institute at Huawei Technology Corporation Limited, unveiled their new quick charging lithium-ion batteries at the 56th Battery Symposium in Japan. Using next generation technology, these new batteries have achieved a charging speed 10 times faster than that of normal batteries, reaching about 50% capacity in mere minutes.
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. These quick charging batteries underwent 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 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. Soon, we will all be able to charge our batteries to full power in the time it takes to grab a coffee!
Huawei’s Watt Lab works closely with industry partners to promote technological development and pursue a new energy era. Watt Lab specifically focuses on the technical development of energy storage to support a better connected world via sufficient energy.
