FAST-CHARGING LITHIUM ION BATTERIES WITH ELECTROLYTES THAT DO NOT REACT ON THE ANODES

Fast-charging lithium ion cells are provided, which have electrolytes that do not react with the cell anodes, but instead form a solid-electrolyte interphase (SEI) on the cathodes. Advantageously, such electrolytes improve the performance of the fast-charging cells, and enhance their lifetime and safety. Various electrolyte solutions and lithium ions are proposed to limit electrolyte interactions to the cathodes, or possibly even minimize or prevent these reactions by coating the cathodes. Redox couples may be used to prevent SEI formation on the anode, while promoting SEI formation on the cathode.
