Silicon Carbide-Derived Carbon Prepared by Fused Salt Electrolysis and Electrochemical Performance

Silicon Carbide-Derived Carbon Prepared by Fused Salt Electrolysis and Electrochemical Performance

A number of carbide-derived carbon (CDC) samples were successfully synthesized by the electrolysis of SiC powder in molten CaCl2. The electrolysis was conducted at different temperatures (850, 900, and 950°C) for 48 h in argon at an applied constant voltage of 3.1 V. The structure of the resulting c...
