ENERGY STORAGE BATTERY AND PREPARATION METHOD THEREOF AND ENERGY STORAGE BATTERY PACK

The present application provides an energy storage battery and a preparation method thereof and an energy storage battery pack. The energy storage battery comprises a cathode cement layer, an anode cement layer and a membrane cement layer arranged between the cathode cement layer and the anode cement layer. The cathode cement layer comprises a cathode conductive grid construction and a cathode conductive cement-based material arranged on both sides of the cathode conductive grid construction. The anode cement layer comprises an anode conductive grid construction and an anode conductive cement-based material arranged on both sides of the anode conductive grid construction. The membrane cement layer comprises an anion exchange resin and a first cement-based material. The energy storage battery provided in the present application can achieve the conversion from cement concrete to new energy products, in which the materials used are low cost and widely available. The energy storage battery provided in the present application can be used in large-scale energy storage systems, in which the electrode materials used have high safety performance compared to those of commercial lithium batteries.
