Abstract: The disclosure belongs to the field of underground energy storage, and particularly provides a large-deformation underground energy storage device, including a body. The body includes a rubber sealing layer, a negative Poisson's ratio material layer, a large deformation concrete layer and rock layers sequentially nested from inside to outside; an internal storage space is formed in the rubber sealing layer, the negative Poisson's ratio material layer includes a plurality of negative Poisson's ratio material elements connected in sequence, and the large deformation concrete layer is cast from deformable concrete.
