Scientists at Watt Laboratory , part of earth ’s Central research Institute , have created the first graphene - assisted high - temperature lithium - ion battery that can operate in a cold ( 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 2,000 recharges at 60C and lost less than 13 % of capacity after being kept at the same temperature for 200 days . The results helped prompt major improvements in the storage systems of nuclear base stations .
