Problems solved by technology

[0002] In the traditional steel shell cell, the steel shell is wrapped with stacked positive and negative pole pieces. Due to the error of the process, there may be burrs on the steel shell or the pole piece, which makes the steel shell and the pole piece come into contact, resulting in battery failure. There is a hidden danger of short circuit and fire in the core. In addition, due to external vibration, the pole pieces may also be misaligned inside the steel shell, which will affect the performance of the battery core.

Embodiment Construction

[0016] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the battery pole piece holder provided by the embodiment of the present invention includes two pole piece holders 10, with reference to figure 2 , each pole piece support 10 includes a bottom surface 15, and a first side 11, a second side 12, a third side 13, and a fourth side 14 vertically fixed on the edge of the bottom 15; the first side 11 is parallel to the second side 12, The third side 13 is parallel to the fourth side 14 .

[0018] The bottom surface 15 has the same shape and size as the pole piece; the two pole piece holders 10 are stacked symmetrically, and the hollow area enclosed inside is used to place the stacked pole piece and diaphragm.

[0019] The thickness of the internal space after the two pole piece holders 10 are stacked symmetrically is greater than or equal to the thickness of the...

Abstract

The invention discloses a battery pole piece holder and relates to the field of a lithium battery. The battery pole piece holder comprises two pole piece holders, wherein each pole piece holder comprises a bottom face, and a first side face, a second side face, a third side face and a fourth side face which are vertically fixedly on edges of the bottom face. The first side face is parallel to thesecond side face. The third side face is parallel to the fourth side face. The bottom face and a pole piece are the same in shape and size. The two pole piece holders are symmetrically stacked up. Hollow areas enclosed in interiors of the two pole piece holders are used for placing stacked pole pieces and diaphragm. The problems such as short circuit or fire resulting from contact of steel shellsand the pole pieces due to burr bulges are avoided. Moreover, leads are supported and the stacked pole pieces are fixed, so malposition of the pole pieces is avoided.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a battery pole piece support. Background technique [0002] In the traditional steel shell cell, the steel shell is wrapped with stacked positive and negative pole pieces. Due to the error of the process, there may be burrs on the steel shell or the pole piece, which makes the steel shell and the pole piece come into contact, resulting in battery failure. There is a hidden danger of short circuit and fire in the core. In addition, due to external vibration, the pole pieces may also be dislocated inside the steel shell, thus affecting the performance of the battery core. Contents of the invention [0003] Aiming at the above problems and technical requirements, the present invention proposes a battery pole piece support. [0004] Technical scheme of the present invention is as follows: [0005] A battery pole piece support, comprising: two pole piece supports, each pole piece ...
