Novel lithium battery structure

The invention discloses a novel lithium battery structure. The novel lithium battery structure comprises an upper cover (1), a sealing ring (2) and a shell (3), wherein the upper cover (1), the sealing ring (2) and the shell (3) form an enclosed cavity (4) for containing electrolyte, a negative terminal (5), a charging hole (6), a vent valve (7) and a positive terminal (8) are arranged at the top part of the upper cover in a protruding manner, a battery cell (13) is arranged in the enclosed cavity (4) and comprises a battery cell skeleton (10), a battery pole core (9) and a heat shrinkage tube (12), and the vent valve comprises a venting cavity (102) penetrating through the upper cover (1) and a valve cover (103) covering the venting cavity. According to the novel lithium battery structure, the powder falling-off problem of the positive electrode and the negative electrode of the lithium battery is solved, the battery cell skeleton is additionally arranged inside the battery to ensure the stability of the bat
