Detailed ways:

As shown in FIG. 1 , the battery cell includes a battery 21 , and a casing composed of a right cover 11 and a left cover 12 .

2 , the inner chamber of the right cover 11 is divided into an upper battery chamber 113 and a lower socket chamber 114 by a partition rib 110 , with symmetrical positioning wings 112 and recessed areas 115 on both sides.

As shown in FIG. 3 , the inner chamber of the left cover 12 is divided into an upper battery chamber 123 and a lower socket chamber 124 by a partition rib 120 , with symmetrical positioning wings 122 and raised ribs 125 on both sides.

See Fig. 1, the charge-discharge protection circuit board 33 is electrically connected with the positive and negative poles of the battery 21 and the socket 40 respectively with lead sheets, and then the gasket 41, the battery 21, the gasket 31, the sponge washer 32, the charge-discharge protection circuit board 33 and the positive electrode plate 34 are put into the cavity surrounded by the battery cavity 123 of the left cover 12 and the battery cavity 113 of the right cover 11; 45 and the negative electrode 46 are put into the cavity formed by the socket chamber 124 of the left cover and the socket chamber 114 of the right cover, wherein the negative electrode 46 is fixed in the negative electrode seat 45, and the positive electrode 42 is fixed in the electrode seat 43, and then The paste block 44 between the negative electrode seat and the electrode seat will bond the two together, the opening of the socket 40 is facing the side hole 111 of the right cover, and the gap between the separating ribs 120 and 110 of the left cover and the right cover can allow The wires connecting the socket with the battery and the charging and discharging protection circuit board pass through.
