Abstract:

Lithium-ion batteries are the most widely used energy storage device, and currently, the rapid development of economy has put forward higher requirements on their performances. Electrode microstructure has significant influence on the battery performance, therefore, elaborate microstructure design and controllable preparation thereof is becoming one of the hot topics in this field. In this paper, according to the latest development trend of lithium ion batteries, the basic electrochemical process and the microstructural characterization technology of the lithium ion battery electrode are enumerated. Then the design and optimization of the electrode in recent years are summarized, and the key microstructural features are discussed. Based on an ideal electrode structure, the latest development in controllable electrode preparation technology is reviewed.

Key words: lithium ion battery, microstructure, preparation technology
