We have investigated the possibility of processingubiquitous and inexpensive precursors to make functional intercalation orcapacitive electrode materials for aqueous electrolyte electrochemical energystorage. Anode materials include various high surface are carbons and some Siand Ti based oxides, while cathode materials are transition metal oxides. Sincethe organic electrolytes used in Li-ion systems are expensive (in part due tothe requirement for a dry handling environment), we turn to the higher ionicconductivity aqueous electrolyte systems. The talk will explore differentelectrode options, the performance of some promising devices in differentconditions, and likely future development paths.
