Charge Transport in Solid-State Composite Polymer Electrolytes Containing Charge-Transfer Complexes

Current research on solid-state organic electrolytes mainly focuses on polymer electrolytes where ion transport is facilitated by chain segmental motion. The ionic conductivity of these polymer electrolytes at room temperature is too low for many practical applications. A limited number of prior reports in the patent and research literature suggest that solid-state organic electrolytes including charge-transfer complexes can have surprisingly high ionic conductivity.^[1-5] It was hypothesized that the ion transport in these types of electrolytes is decoupled from the matrix dynamics. This talk will discuss our group’s research findings on charge transport behavior in solid-state composite electrolytes containing charge-transfer complexes.
