• Poly（ethylene oxide）（PEO） as a kind of promising candidates of polymer electrolyte is widely applied in all solid lithium ion batteries. In this study, a novel ceramic composite solid electrolyte（CLASP） was prepared by dip-coating PEO-LAGP-SN-Li TFSI（PEO-SPE） into Al2O3 nonwoven membrane. And all solid batteries were assembled with CLASP. CLASP showed excellent thermostability even at 170℃ for 2 h. When the ratio of PEO: LAGP: SN: Li TFSI was 3: 1: 1: 1, the conductivities of CLASP reached 3.66×10-5 S/cm at 25℃ and 2.52×10-4 S/cm at 100℃, respectively. The electrochemical window of CLASP was 5.5 V, which had great potential to apply in battery with high voltage cathode material. The cycling performance of all solid batteries with CLASP was greatly improved at 55℃ as well. This new ceramic composite, solid polymer electrolyte, with all these outstanding performance is a promising candidate of all solid electrolytes.
