摘要

Changing climate and decreasing availability of fossil fuels stimulate the use of alternative energy sources and energy storage devices such as electrochemical capacitors The current study investigates the implementation of SPPS (Solution Precursor Plasma Spraying) for the deposition of high surface area electrochemical capacitor electrodes. A high performance MoxN electrochemical capacitor electrode was produced by solution precursor plasma spraying for the first time. The best electrode exhibited an initial capacitance of 62.4 mF cm-2 at a scan rate of 100 mV sec-1. The capacitance decreased by 22% after the first 1000 cycles, but the performance then stabilized, decreasing by only 0.15% over cycles 4000 to 5000 and exhibiting a capacitance of 30mF cm-2 after 5000 cycles. SPPS is a novel deposition method, thus further understanding and optimization of the process is required to improve the performance and manufacturability, but a clear potential was proven.
