Rational Design of Composite Solid Electrolyte for Structural Energy Storage

The objective of this proposed research is to develop structural energy storage devices, and understand its mechanical/electrochemical behaviors. Proposal aims to develop ceramic/polymer composite solid electrolytes to address this challenge. In such a composite electrolyte, ceramic, the major phase, provides enough strength against compression and shock, while the polymer renders the composite flexible. Research will answer how to design composite solid electrolyte with simultaneous high ionic conductivity and high mechanical robustness, and how to achieve low resistance and high adhesion at electrode/electrolyte interface simultaneously. Moreover, due to their intrinsic nonflammability, ceramic-based solid electrolytes could provide safer solutions than organic electrolyte.
