Are solid-state batteries a viable alternative to a lithium anode?

Solid-state batteries are currently of great interest in the research community since they can in practice increase the energy density of the cells by removing the need for the separator and would allow the use of lithium anode since the dendrite formation is suppressed.

How does a composite positive electrode affect battery performance?

One key discovery is the overpotentials caused by concentration polarization and interfacial reactions within the positive electrode particles, which serve as rate-limiting factors. Furthermore, the particle radius and effective contact area within the composite positive electrode exert a substantial influence on battery performance.
