Cathode Materials and Electrolytes for Magnesium Secondary Batteries

Magnesium secondary batteries have recently attracted much attention as a potential candidate for heavy load batteries. However, the development of Mg secondary batteries has been hindered because it is difficult to find the appropriate cathode materials and non-aqueous electrolytes. In this paper, the recent research advances of key technologies on Mg secondary batteries are reviewed with details of cathode materials and electrolytes, especially on Mo6S8 cathode material and Mg(AX(3-n)R(n')R(n '')')(2)/THE electrolyte with favorable performance(A = Al, B, Sn, etc.; X = Cl, Br; R, R' = alkyl or aryl;. 0 < n < 4; n' + n(n) = n). The specific capacity is similar to 100mAh center dot g(-1) for the above cathode material in the Mg secondary batteries. Furthermore, the current problems as well as the corresponding research directions are discussed, and the possible application prospects is also proposed.
