Abstract: Provided is an electrical storage system including an electrical storage unit that includes one or two or more storage batteries, a storage unit that stores historical information of the electrical storage unit, and a control unit. The control unit acquires the historical information from the storage unit, and performs a control of changing a charging setting voltage value of the electrical storage unit to a low-charging voltage value lower than a typical-charging voltage value in a case where the charging setting voltage value of the electrical storage unit is set to the typical-charging voltage value and in a case where the historical information satisfies a voltage changing condition, and of returning the charging setting voltage value of the electrical storage unit to the typical-charging voltage value after the electrical storage unit performs charging and discharging with the low-charging voltage value.

The method heats the metallorganic compound, and as a result of the heating, decomposes materials in the metallorganic compound. In one aspect, decomposing the materials in the metallorganic compound includes forming a chemical reaction between the Me particles and the materials. An electrode is formed of Me particles coated by the materials.
