Types of Solid Electrolytes Solid-state batteries differ from classical lithium-ion batteries due to their use of a solid electrolyte. However, a consensus on the preferred chemistry for the solid electrolyte has not been reached, as each type comes with distinct pros and cons. The two most common families of electrolyte used are:
Ceramic (including Oxides and Sulphides)
Polymers (solid, composite, or gel; the latter often referred to as a semi-solid electrolyte) Key properties of a good solid-state electrolyte include high ionic conductivity, a robust electrode-electrolyte interface, high thermal and electrochemical stability, the ability to suppress dendrites, high processability, and low manufacturing cost. Ceramic electrolytes exhibit high ionic conductivity and mechanical strength but suffer from poor interfacial properties. In contrast, organic polymers boast good interfacial properties but struggle with low ionic conductivity and mechanical strength. So far, polymers have achieved a higher level of technology readiness owing to their superior processability.
