In the recent decades, lithium-ion batteries have became more necessary energy storage device for the common life in the scene that the fossil energy and energy consumption have been gradually exhausted. Even it overcame nearly 30 years of researchs and developments, it still have had a lot of matters those are paying numerous attentions to make it more perfect and those issues are the safety, the operability temperature and the power density performance. To solve metioned above current problems, in this work, a straightforward method was taken to address the current problems associated with ASSLBs by using a combination series of all candidates that have been examined in the previous several years, including PEO, LLZO, SN, and Li salts, among others. In this study, LLZO was synthesized at low temperature using the modified sol – gel Pechini process, which included a tiny amount of Al3+ and Nb5+ co-dopants cation. A major role in the development of improved solid polymer electrolytes (SPEs) that are functional at room temperature was performed by the elements Nb, Al – LLZO (NAL) and SN, among other elements. It has been discovered that the electrolyte PEO/LiTFSI-SN-NAL (PLS-NAL) has strong ionic conductivity (3.04 x 10-4 S cm-1) and an excellent lithium-ion transference number (0.7), even when used at ambient temperature. Both at ambient temperature and at 45 degrees Celsius, the ASSLBs integrated LiFePO4 and PLS – NAL demonstrated outstanding cycling stability with high restitution of over 90% after 200 cycles.
