the authors present a method for calculating the energy balance of the process of obtaining graphite powder by electrolysis. Energy balance data are important for assessing the energy efficiency of an electrochemical device and identifying reserves for reducing the specific energy consumption. The regularities of energy distribution inside the electrolyzer system are determine
energy balance, electrochemical reaction, specific power consumption, fine graphite powder
