Objectives
1.   To synthesize ionic covalent organic frameworks (iCOFs) solid electrolytes, including  fluorosulfonylimide-COFs (FSI-COFs), imidazolate-ether COFs (Im-Ether-COFs), and anthraquinone silicate COFs (AQ-Si-COFs), which can effectively conduct Li+ with high conductivity (σLi+) and transference number (tLi+) (Y. KIM)2.   To theoretically study the mechanisms of Li+ transport through the iCOFs solid electrolytes (Y. WANG)3.   To fabricate all-solid-state LMB cells (cathodes: LCO, NMC and sulfur) containing the COFs solid electrolytes and characterize these cells’ performance. (D.M. SHIN, and Z.L XU)
