A Beijing-based company has developed the world’s first graphene lithium-ion AA rechargeable batteries in the city and said its ready to be mass produced and officially hit the market.
Compared with ordinary AA dry batteries and rechargeable batteries, Carbon Century Technology Co.’s graphene batteries can be used 30,000 times under temperatures between -45 degrees Celsius and 60 degrees Celsius, Chinanews.com cited the company as saying two days ago.
Working temperatures for ordinary, nickel-metal hydride batteries are between 0 and 40 degrees Celsius and normal lithium batteries are best used between -10 and 40 degrees Celsius.
Carbon Century’s new batteries use graphene for the framework of electrode materials to increase their strength, which enhances the overall life of lithium batteries and improves micro-conductivity and batter safety, said Chairman Yan Liqun.
