The present invention provides an electrochemical energy storage device. The electrochemical energy storage device comprises an electrical core (1), an electrolyte and a packaging casing (2). The electrochemical energy storage device further comprises a glue material (3) located between the electrical core (1) and the packaging casing (2). The glue material (3) comprises a first adhesive layer (31) and a second functional layer (32). The first adhesive layer (31) is bonded directly or indirectly on the outer surface of the electrical core (1); the second functional layer (32) is arranged on one side opposite to the surface, of the electrical core (1), on which the first adhesive layer (31) is bonded directly or indirectly, before a pressure is applied to the electrochemical energy storage device, the electrical core (1) is not bonded with the packaging casing (2), and after the pressure is applied to the electrochemical energy storage device, the electrical core (1) is bonded with the packaging casing (2).
