US Patent Issued on Nov. 4 for "High voltage electrolyte for 5V solid state lithium-ion battery cell" (California Inventor)

ALEXANDRIA, Va., Nov. 6 -- United States Patent no. 12,463,245, issued on Nov. 4.

"High voltage electrolyte for 5V solid state lithium-ion battery cell" was invented by Zhigang Lin (Garden Grove, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "High voltage, high-ionic-conductivity, fire resistant solid-state polymer electrolytes include poly(vinylidene fluoride-co-hexafluoropropylene) P(VDF-HFP), sulfolane plasticizer, lithium salt, and ceramic nanoparticles with the basic formula Li7La3Zr2O12 (LLZO) and derivatives thereof. During the curing process, the presence of the LLZO nanoparticles prevent the P(VDF-HFP) from developing into a crystalline phase. In the electrolyte formed, the P(VDF-HFP) is in a...
