Battery structure

Abstract

A battery structure comprising a battery cover plate structure including a current collector (7), characterized in that the current collector (7) comprises a first connecting portion (71), a bending-resistant portion (72) and a second connecting portion (73); wherein the first connecting portion (71) and the second connecting portion (73) are connected via the bending-resistant portion (72); and further comprising: an electrode post (2) comprising an electrode post holder (22) and an electrode post body (21), wherein the first connecting portion (71) of the current collector (7) is connected to the electrode post holder (22); a battery cover structure (5) comprising a recessed portion (52), wherein a through-cover hole (51) is formed in the battery cover structure (5); a terminal (1); wherein the electrode column body (21) is connected to the terminal (1) through a hole (51) through the cover structure;the terminal (1) is disposed on one side of the battery cover (5), and the current collector (7) is disposed on the other, opposite side of the battery cover (5); an upper plastic (3) arranged in the recessed portion (52), wherein an upper plastic hole (31) is formed in the upper plastic (3), and the upper plastic hole (31) is connected to the hole (51) passing through the cover; the electrode column body (21) is inserted into the upper plastic hole (31) and connected to the terminal (1); the upper plastic (3) is provided with a plastic protrusion (32), and the plastic protrusion (32) abuts the terminal (1); a lower plastic (6) arranged between the battery cover (5) and the current collector (7), wherein a lower plastic hole (61) is formed in the lower plastic (6), and the electrode column body (21) is fitted into the lower plastic hole (61) and connected to the terminal (1);and a sealing ring (4) which is pulled onto and connected to the electrode column body (21);
