Surface Modifications of Li-Ion Battery Active Materials with Polymers for Improved Performance

摘要

1. A stable SEI is essential for protecting AM from corrosion by electrolyte 2. The nature (composition, microstructure) of SEI has tremendous effects on the charge transfer resistance 3. Complicated additive chemistries for creating optimum SEI However, 1. Li dendrite formation during charging-discharging cycles a. Span the interelectrode space b. Short circuit the cell c. Cause overheating and thermal runaway 2. Low Columbic efficiency 3. Thickness limitation for Li foil.
