Overall, the physical contact at the solid-state battery interface has a significant impact on the battery performance. By optimizing the physical contact between the solid-state electrolyte and the lithium cathode, the battery performance and stability can be improved. 6. Conclusions and outlook
The following is a summary of the physical contact at the interface of solid-state batteries: (1) Interfacial impedance: The interfacial impedance of a solid-state battery cell is influenced by the intimate contact between the solid electrolyte and the lithium cathode.
In addition, a quantitative analysis on welded test samples reveals the ultimate tensile strength and heat input into a battery cell. A novel measuring and calculation method was designed and applied to assess the electrical contact resistance itself. The electrical contact resistance occurs as a result of the joint and not in the bulk material.
In this paper the energy loss due to electrical contact resistance (ECR) at the interface of electrodes and current-collector bars in Li-ion battery assemblies is investigated for the first time. ECR is a direct result of contact surface imperfections and acts as an ohmic resistance at the electrode-collector joints.
The complex electrochemical behavior that occurs in the interface between solid electrolyte and electrode materials, challenges the materials scientists to address the interfacial issues in solid-state batteries. The poor ionic conductivity and poor contact between the cathode and solid electrolyte cause poor cathode interface performance.
Every single cell connection influences the functionality and efficiency of the whole battery system. Resistance spot, ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies.
