Abstract

The invention discloses a lithium battery. The lithium battery comprises a positive electrode, a negative electrode and an electrolyte solution, wherein the positive electrode is LiCF<3>SO<3>; the negative electrode is LiMn<2>O<4>; and the electrolyte solution is one or combination of ethylene carbonate, propylene carbonate, diethyl carbonate, propyl acetate, dimethyl carbonate, ethyl methyl carbonate, polyvinyl difluoride, and polyamide. Compared with the prior art, the lithium battery has the advantages as follows: by virtue of the abovementioned technical scheme, the raw material cost of the lithium battery is greatly lowered, so that the lithium battery has relatively high market competitiveness; and in addition, the popularization and application of the lithium battery can be facilitated.

Description

technical field [0001] The invention relates to a lithium battery, in particular to a large-capacity lithium battery. 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 sulfur and other battery energy stor...
