Abstract
Adhesive composite electrolytes are of great interest due to the potential for achieving a good balance among electrochemical, mechanical and interfacial properties. However, for composite electrolytes, the commonly used organic or inorganic fillers have limited contributions to mechanical properties and/or adhesion properties. In this study, abundant proteins are employed as unique fillers to fabricate composite electrolytes with improved mechanical and adhesion properties. The contribution of two types of proteins including animal-derived (gelatin) and plantderived (soy protein) proteins to the significant properties of composite electrolytes (mechanical properties, ionic conductivity and adhesion properties) is investigated and compared with other solid fillers (eg. wax particles). It is found that proteins, particularly gelatin, cannot only notably improve the modulus and elasticity, but also the adhesion properties, while the high ionic conductivity of the electrolyte matrix can be maintained simultaneously. The possible mechanism responsible for the significant improvement is further discussed. This study indicates that natural proteins are promising in fabricating high-performance composite electrolytes.
