JOHANNESBURG – THE world’s first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures has been unveiled.

Huawei announced the battery made by Watt Laboratory, an organization under its Central Research Institute made by as a major breakthrough.

Research results show that new graphene-based heat-resistant technologies allow Li-ion batteries to remain functional in a 60°C environment, a temperature 10°C higher than the existing upper limit.

The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as ordinary Li-ion batteries.

Yangxing Li, Chief Scientist at Watt Laboratory, pointed out three technologies contributed to the breakthrough in the graphene-assisted high-temperature Li-ion battery.

First, a special additive in the electrolytes can remove trace water and prevent the electrolytes from evaporating in high temperatures.

Second, modified large-crystal NMC materials are used for the cathode, improving the thermal stability of the cathode powder. Third, graphene allows for more efficient cooling of the Li-ion battery.
