摘要： An energy-storage device, an electricity-consumption system, and an energy-storage system are provided in the disclosure. The energy-storage device includes multiple energy-storage units, an isolation plate, a first thermal insulator, and a second thermal insulator. The multiple energy-storage units are sequentially arranged in a first direction. Each of the multiple energy-storage units includes an explosion-proof valve. The isolation plate is located at one side of each of the multiple energy-storage units where the explosion-proof valve is located, extends in the first direction, and defines multiple vents arranged at intervals in the first direction. Each of the multiple vents is at least partially aligned with a corresponding explosion-proof valve, and different explosion-proof valves are aligned with different vents. The first thermal insulator and the second thermal insulator are both located at one side of the isolation plate away from the multiple energy-storage units.
