Battery electrodes are the two electrodes that act as positive and negative electrodes in a lithium-ion battery, storing and releasing charge. The fabrication process of electrodes directly determines the formation of its microstructure and further affects the overall performance of battery.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
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.
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.
After calendering, the contact between electrode particles and particles and fluid collector is closer, which can effectively increase the compacting density of positive and negative electrode materials , so as to improve electrode conductivity and battery volume energy density [15, 104].
Chemical reactions can cause the expansion and contraction of electrode particles and further trigger fatigue and damage of electrode materials, thus shortening the battery life. In addition, the electrode microstructure affects the safety performance of the battery.
