Description

Technical field [0001] The invention relates to the field of batteries, in particular to multi-carbon batteries. Background technique [0002] An electric vehicle refers to a vehicle that is powered by an on-board power supply and driven by a motor to drive wheels, and meets the requirements of road traffic and safety regulations. As the environmental impact is relatively small compared to traditional cars, its prospects are widely optimistic, and batteries are an indispensable accessory in electric vehicles. Traditional batteries (such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries) have disadvantages such as long charging time and short cycle life, which have seriously affected the development of electric vehicles. Summary of the invention [0003] Aiming at the shortcomings of long battery charging time and short cycle life of electric vehicles in the prior art, the present invention provides a multi-carbon battery. ...
