Disclosed is a multi-buffering energy storage device and an application thereof. The multi-buffering energy storage device comprises an energy storage cylinder (3), an oil tank (27), a first spiral spring mechanism (28), a second spiral spring mechanism (29), a hydraulic motor (24), a differential planetary gear train (20), and a power generator (26). The energy storage cylinder (3) comprises an airtight cylinder body, wherein one end of the airtight cylinder body is provided with a flexible mobile device, and the other end thereof is provided with an energy transfer device. Hydraulic oil is filled between the flexible mobile device and the energy transfer device. The airtight cylinder body, the hydraulic motor (24), and the oil tank (27) are connected via an oil circuit to form a hydraulic circuit. The energy transfer device is connected to the first spiral spring mechanism (28), the hydraulic motor (24) is connected to the second spiral spring mechanism (29), and the first spiral spring mechanism (28) and t
