Scientists at Watt Laboratory, part of Huawei’s Central Research Institute, have created the first graphene-assisted high-temperature lithium-ion battery that can function in a 2,000 (140F) environment. This record is 10 degrees higher than previously achieved. Dr Yangxing Li said tests showed the battery was five degrees cooler than traditional lithium-ion varieties. It also retained more than 70% of its capacity after 60C recharges at 2,000 and lost less than 13% of capacity after being kept at the same temperature for 200 days. The results could prompt major changes in the storage systems of communications base stations.
