The electrochemical reduction mechanism of Mn in LiMn2O4 molten salt was studied. results show that the NaCl-CaCl2 salt, process reducing from (IV) to manganese is: (IV)→Mn (III)→Mn (II)→Mn. reacts with form CaMn2O4 after being placed for 1 h. reaction is divided into two steps: constant voltage deoxidation experiments under different conditions intermediate products are CaMn2O4, MnO, and (MnO)...
