Advanced Double Layer Capacitor

Authors: Anthony B. LaConti; Philip Lessner; S. Saragapani; GINER INC WALTHAM MA
Abstract:
The overall goal of this project is to develop electrochemical capacitors with no liquid electrolyte present. The liquid electrolyte is replaced by a solid ionomer electrolyte. An advantage of these devices over conventional electrochemical capacitors containing free acid would be greater safety and reliability. In the fourth quarter, we concentrated our efforts in three areas: 1) preparation and characterization of RuOx powders, 2) preparation of membrane and electrode (M and E) assemblies with high capacitance, and 3) scale-up of M and E structures to 2 x 2 size. Keywords: Electrochemistry. (JES)
