The role of SEI in lithium and lithium ion batteries
- Tel Aviv Univ. (Israel). School of Chemistry
This paper presents and discusses fundamental processes taking place at the lithium and Li{sub x}C{sub 6} electrode/electrolyte interphases and models for these interphases. The authors deal with both nonaqueous and polymer (dry and gel) electrolytes, graphitized and nongraphitized carbonaceous materials as anodes for Li-ion batteries. Each electrode/electrolyte combination has its own unique features and problems but there are some general phenomena common to all of them. Issues to be reviewed include SEI composition, morphology and formation reactions, graphite surface modifications including chemical bonded SEI and micro channels formation, electrode degradation processes, lithium deposition-dissolution and intercalation-deintercalation mechanisms, rate-determining steps (RDS), electrolyte and electrode parameters and conditions affecting the above mentioned processes. Technology-related issues are emphasized.
