At present, liquid lithium batteries have almost reached their limit, and solid-state lithium batteries are the only way for the development of lithium batteries. The most important performance indicators of solid-state electrolytes are ionic conductivity, electronic conductivity and interface stability, among which the most important is interface control.
Technical challenges of solid-state electrolytes · Balance of ionic and electronic conductivity · Poor solid-solid interface contact between electrode and solid electrolyte resulting in high impedance · Process complexity | Limitations of current conductivity measurements of solid electrolytes ·Frequency limitation: conventional electrochemical workstation frequency (≤10MHz). ·Non-situ test defects: impedance measurement after non-situ or low-voltage tableting ·Lack of temperature control system ·Equipment cost and function limitations |
