A compressed-air energy storage system of a constant-pressure full-capacity energy-release type, includes two or more liquid-gas coexisting containers, at least one of the two or more liquid-gas coexisting containers is filled with a pressurized liquid, the rest liquid-gas coexisting containers are configured to store a high-pressure air, and the two or more liquid-gas coexisting containers are in communication with each other. When the compressed-air energy storage system of the constant-pressure full-capacity energy-release type operates in an energy storage operating condition, the high-pressure air can be directly stored in the liquid-gas coexisting container without energy conversion loss. When the compressed-air energy storage system operates in an energy release operating condition, the pressurized liquid circulates in the liquid-gas coexisting containers storing the high-pressure air, to realize a constant-pressure full-capacity release of the high-pressure air.
