Abstract

The invention discloses a battery for an electric vehicle. The battery comprises a positive electrode, a negative electrode and an electrolyte solution, wherein each of the positive electrode and the negative electrode comprises a salt of which cations are lithium; the electrolyte solution comprises an organic solvent, polyvinyl-difluoride, styrene butadiene rubber, polyamide or a composition of the polyvinyl-difluoride, the styrene butadiene rubber and the polyamide. Compared with the prior art, the battery for the electric vehicle has the advantages that the raw material cost can be greatly reduced by the lithium battery through the technical scheme, the lithium battery has a relatively strong competition advantage in the market and improvement of popularization and application of the lithium battery is facilitated.

Description

technical field [0001] The invention relates to a battery for electric vehicles, in particular to a battery with large capacity for electric vehicles. Background technique [0002] Energy shortage and climate change have drawn global attention to electric vehicles, which have the advantages of energy saving and environmental protection. Electric vehicles use electricity to replace fossil fuels such as petroleum as power, and are the only long-term solution for future transportation. Current research hotspots related to electric vehicles include electric vehicle motor drive system, electric vehicle charger technology, charging harmonic analysis and charging station monitoring system, among which electric vehicle battery technology is regarded as the most important difficulty. [0003] The energy storage technology applied to electric vehicles is mainly electrochemical energy storage technology, that is, lead-acid, nickel metal hydride, nickel cadmium, lithium ion, sodium sul...
