Solid-state electrolytes with non-flammable and eco-friendly properties are expected to alleviate their safety concerns, which have become a research focus in the research field of Li-air batteries (LABs). Herein, an overview of the recent progress in SSE-based LAB (SSLABs) by categories of gel polymer electrolyte, solid polymer electrolyte, solid inorganic electrolyte, and solid composite electrolyte based batteries and the remaining interfacial challenges and possible solutions for the further development of SSLABs.
Among the promising batteries for electric vehicles, rechargeable Li-air (O2) batteries (LABs) have risen keen interest due to their high energy density. However, safety issues of conventional nonaqueous electrolytes remain the bottleneck of practical implementation of LABs. Solid-state electrolytes (SSEs) with non-flammable and eco-friendly properties are expected to alleviate their safety concerns, which have become a research focus in the research field of LABs. Herein, we present a systematic review on the progress of SSEs for rechargeable LABs, mainly focusing on the interfacial issues existing between the SSEs and electrodes. The discussion highlights the challenges and feasible strategies for designing suitable SSEs for LABs.
