Problems solved by technology
However, the low power density of lithium-ion batteries is a major factor restricting their use as vehicle power
[0003] At present, the effective way to solve the above problems is to use a high-power electrolyte with both high and low temperature, but the current high-power electrolyte with both high and low temperature is a technical problem in this field, because the solvents, additives and lithium salts used in the electrolyte all exist Defects such as high and low temperature cannot be taken into account, and battery power density cannot be improved

Abstract
The invention belongs to the technical field of lithium ion batteries, and in particular relates to a high-power electrolyte and a lithium ion battery containing the electrolyte. The invention adopts nickel-cobalt lithium manganese oxide cathode material with high energy density and good power performance, and simultaneously uses solvent with high lithium ion mobility, additive combination and lithium salt to improve the power performance of electrolyte performance. The electrolyte additive of the invention can form a protective film with higher strength on the surface of the positive and negative electrodes, thereby improving the high-temperature performance of the battery. At the same time, a lithium salt with a higher decomposition temperature is used, thereby improving the safety performance of the lithium-ion battery.
Description
technical field [0001] The invention belongs to the technical field of lithium ion batteries, and in particular relates to a high-power electrolyte and a lithium ion battery containing the electrolyte. Background technique [0002] Resource shortage, energy crisis and environmental pollution are severe challenges facing human production at present. Finding renewable and resource-saving secondary energy is one of the urgent tasks to be solved for the sustainable development of human society. Lithium-ion batteries have been widely used in the field of electric vehicles as a green power. However, the low power density of lithium-ion batteries is a major factor restricting their use as vehicle power. [0003] At present, the effective way to solve the above problems is to use a high-power electrolyte with both high and low temperature, but the current high-power electrolyte with both high and low temperature is a technical problem in this field, because the solvents, additives ...
