Aluminum electrolysis is known as more energy consumption and more pollution. The DC power of aluminum electrolysis before the technology of aluminum reduction cells with a new-type of cathodes design being applied in China was over 13000 kWh/t. After 2010, nearly all the aluminum smelters have began to use the technology of new type of cathode design and 500–700 kWh/t of aluminum reduction can be achieved easily. The DC power of aluminum electrolysis is nowadays 12100~12300 kWh/t. 11800 kWh DC energy power of an aluminum reduction cell in Chuangyuan Smelter is achieved. In present paper, Research and application of energy saving technology are given, and a new anode technology is presented. By using the new technology of anode, cathode and narrow central channel, the energy consumption will be decreased greatly.
