Category (FI): H01M10/0569,H01M4/525,H01M4/505,H01M4/36@C,H01M10/052,H01M10/0567
Stage: PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte capable of improving the performance and life of Li ion batteries while reducing costs over other systems that rely on more additives.SOLUTION: A nonaqueous electrolyte for a lithium ion battery includes a lithium salt, a first nonaqueous solvent, and an additive mixture comprising a first operative additive of lithium difluorophosphate and a second operative additive of either fluoro ethylene carbonate or vinylene carbonate. A lithium ion battery includes a negative electrode, a positive electrode comprising NMC with micrometer-scale particles, a nonaqueous electrolyte having lithium ions dissolved in a first nonaqueous solvent, and an additive mixture having a first operative additive of either fluoro ethylene carbonate or vinylene carbonate and a second operative additive of either 1,3,2-dioxathiolane-2,2-dioxide, another sulfur-containing additive, or lithium difluorophosphate.SELECTED DRAWING: Figure 46D (Grant)
