The ultra-thin SPEs, as the link between the cathode and anode, not only affect the performance of the battery by their own properties, but also significantly affect the overall efficiency of the battery by the interactions at the interfaces.
Based on the current cathode and anode material system, the ultra-thinning of solid polymeric electrolytes (< 20 μm) is the only way to realize energy-dense properties (>500 Wh kg −1) and high-rate performance (charge at 5 C).
At present, there are commercially available polyethylene oxide (PEO)-based solid-state batteries. However, the large thickness of the solid polymeric electrolyte (> 60 μm) increases the volume ratio of inactive components in the battery, and its ionic conductivity is far below that of the liquid electrolyte.
All-solid-state lithium batteries (ASSLBs) have become fantastic energy storage devices with intrinsic safety and high energy density. The solid electrolyte is located between the cathode and anode and is decisive for conducting lithium ion, which is crucial to the energy density, fast-charging performance and safety of ASSLBs.
