The development of all solid‐state rechargeable magnesium battery systems is reported, with components that are environmentally friendly and relatively simple in their structure and preparation. As anodes, magnesium alloys containing Zn and Al are used, and the cathode is the chevrel phase, Mo 6 S 8 , which can insert two magnesium atoms per unit (Mg 2 Mo 6 S 8 , 122 mA h g –1 ). The solid electrolyte is a gel comprising polyvinylidene difluoride, Mg(AlCl 2 EtBt) 2 complex salt, and tetraglyme as a plasticizer. These batteries are found to function well in a temperature range of 0–80 °C with a voltage range of 1.3–0.8V.
