(Yicai Global) Dec. 1 -- A major breakthrough in the lithium battery industry has been made by Watt Lab in making the first long-lifespan graphene-assisted Li-ion battery able to withstand high temperatures. The lab is affiliated to the Central Research Institute at China's largest smartphone maker Huawei Technologies Co.
Research results show that the new graphene-based heat-resistant technologies developed by Huawei can increase the upper limit on temperature, under which Li-ion batteries remain functional, by 10°C, NetEase Technology reported.
The lifespan of the graphene-assisted Li-ion batteries will also be twice as long as that of ordinary Li-ion batteries.
In high-temperature regions, outdoor base stations powered by graphene-assisted high-temperature Li-ion batteries can have working lifespans of over four years, Huawei said.
These batteries can also ensure a high mileage for electric vehicles per charge in high temperatures and guarantee the safe operation of drones, which often generate a significant amount of heat.
