CROSSLINKED POLYMERS AND RELATED COMPOSITIONS, ELECTROCHEMICAL CELLS, BATTERIES, METHODS AND SYSTEMS

Crosslinked polymers and related compositions and related compositions, electrochemical cells, batteries, methods and systems are described. The crosslinked polymers have at least one redox active monomeric moiety having a redox potential of 0.5 V to 3.0 V with reference to Li/Li electrode potential under standard conditions or −2.54 V to −0.04 V vs. SHE and has a carbocyclic structure and at least one carbonyl group or a carboxyl group on the carbocyclic structure. The crosslinked polymers also include at least one comonomeric moiety with at least one of the at least one redox active monomeric moiety and/or the at least one comonomeric moiety has a denticity of three to six corresponding to a three to six connected network polymer, and provide stable, high capacity organic electrode materials.
