LITHIUM ION BATTERIES WITH HIGH VOLTAGE ELECTROLYTE ADDITIVES

A lithium ion battery includes a cathode, an anode, and an electrolyte. The electrolyte includes a lithium salt, a solvent, a first additive, and a second additive. The first additive contributes to formation of a cathode solid electrolyte interface (SEI) on a surface of the cathode. The second addi...

Beschreibung
Zusammenfassung:	A lithium ion battery includes a cathode, an anode, and an electrolyte. The electrolyte includes a lithium salt, a solvent, a first additive, and a second additive. The first additive contributes to formation of a cathode solid electrolyte interface (SEI) on a surface of the cathode. The second additive contributes to formation of an anode SEI on a surface of the anode. The first additive is one or more of a phosphonite compound, a phosphoranylidene compound, or a fluorocyclophosphazene compound
