  "textContent": "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 LiLaZrO(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 an amorphous phase with LLZO nanoparticles, lithium salt and sulfolane distributed in the polymer matrix. The solid-state electrolyte with the amorphous polymer phase exhibit higher ionic conductivities than those having a crystalline polymer phase. The LLZO contributes to mechanical properties of the electrolyte and also function as tough ceramic fillers that inhibit lithium dendrite growth during operation of lithium-ion cells and batteries. 5V all-solid-state lithium-ion batteries incorporated the electrolytes exhibit high energy densities (250-350 Whr/kg), high power densities (high discharge rate up to 5 C) and long service lives (500-1500 cycles,",
