Huawei announced a major breakthrough in its research into Li-ion batteries, unveiling the world's first long-lifespan graphene-assisted Li-ion battery able to withstand high temperature. The announcement was made by Watt Laboratory, an organization under Huawei's Central Research Institute, at the 57th Battery Symposium held in Japan.
The new graphene-based heat-resistant technologies allows Li-ion battery to remain functional in a 60-degree Celcius environment and also be twice lifespan compare to the ordinary Li-ion batteries.



There are three technologies contributed to the new breakthrough. First, a special additive in electrolytes can remove trace water and prevent the electrolytes from evaporating in high temperature. Second, modified large-crystal NMC materials are used for the cathode, improving the thermal stability of the cathode powder. Lastly, graphene allows for more efficient cooling of the Li-ion battery.

These batteries ensure a high mileage for electric vehicles per charge in high temperatures and guarantee the safe operation.

Beside introducing the new Graphene-assisted Li-ion Battery, Huawei's Watt Laboratory also revealed its quick charging technology. It can recharge 48% of a 3,000mAh battery in just 5 minutes and Huawei will commercialized the developed quick charging batteries. It will be announce the super-quick charging mobile phone in late December.
