Abstract

Abstract: The development of lithium ion battery with high energy density is one of the key means to achieve long mileage for new energy vehicles, especially for pure electric vehicles. However, with the continuous improvement of battery energy density, the cycle life and safety performance of batteries will be decreased. Taking the cell with energy density of 300W·h/Kg as the target, this paper discusses the material chemistry, the design of cell structure and the safety protection measures of the system, and explores the technical route of lithium ion battery system with high safety and high energy density.

Key words: high safety, high energy density, lithium ion battery, route exploration
