Presently, the literature on modeling the composite positive electrode solid-state batteries is limited, primarily attributed to its early stage of research. In terms of obtaining battery parameters, previous researchers have done a lot of work for reference.
Positive electrodes for Li-ion and lithium batteries (also termed “cathodes”) have been under intense scrutiny since the advent of the Li-ion cell in 1991. This is especially true in the past decade.
This perspective discusses key advantages of alloy anode materials for solid-state batteries, including the avoidance of the short circuiting observed with lithium metal and the chemo-mechanical stabilization of the solid-electrolyte interphase.
To achieve this potential, however, solid-state batteries require the use of electrode materials with high charge storage capacity and long-term stability.
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.
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.
