Lithium ion battery generally has two kinds of external forms:Column type and rectangle.Rectangle structure battery is more convenient due to assembling, Space availability ratio is high, so more being liked by numerous clients and manufacturer.In rectangular battery production process, because design needs Will, often branched little battery core is welded and be combined into a big battery core, then big battery core circulates and produce battery.Little battery core is being welded When being combined into big battery core, conventional method is to be coupled together little battery core by tab welding.Although cell polar ear is long when producing Degree is identical, but in combination due to position relationship, the lug in intermediate layer always than upper strata or lower floor lug from weldering Point is more recently.In order to solve the problems, such as that during tab welding, diverse location cell polar ear is different apart from solder joint length, common does Method is first to carry out lug prewelding before tab welding, is then sliced out unnecessary lug and has reached the smooth purpose of lug.But it is this The production process of battery core needs to increase prewelding and excision step, can increase the technological process of battery core production, increased battery core and produces Cost and certain uncertain factor.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, now provides a kind of combination electricity of lithium ion battery Core, to solve the problems, such as the increase prewelding in cell production process and the steps such as excision, can reduce the manufacturing cost of equipment, improve Production efficiency.
For solving above-mentioned technical problem, the technical solution adopted in the utility model is:A kind of combination electricity of lithium ion battery Core, its innovative point is:Including the upper strata battery core setting gradually from top to bottom, middle battery core and lower floor's battery core;Described upper strata electricity The right flank of core is symmetrically arranged with positive pole upper strata lug and negative pole upper strata lug;The right flank of described middle battery core is symmetrically arranged with Lug and the middle lug of negative pole in the middle of positive pole;The right flank of described lower floor battery core is provided with positive pole lower floor lug and negative pole lower floor pole Ear;In the middle of described positive pole upper strata lug, positive pole, lug and positive pole lower floor lug are located on same vertical line, negative pole upper strata lug, In the middle of negative pole, lug and negative pole lower floor lug are located on same vertical line, and are disposed as rectangle structure;Described positive pole upper strata Lug, the length of negative pole upper strata lug, positive pole lower floor lug and negative pole lower floor lug are set to same length;In the middle of described positive pole In the middle of the length of lug and negative pole, the length of lug is set to same length;The length of described positive pole upper strata lug>In the middle of positive pole The length of lug.
Further, in the middle of described positive pole the length of lug and positive pole centre lug to positive pole upper strata lug height, with And the length of positive pole upper strata lug meets Pythagorean theorem;In the middle of described negative pole, the length of lug and the middle lug of negative pole are on negative pole The height of layer lug, and the length of negative pole upper strata lug meets Pythagorean theorem.
The beneficial effects of the utility model are as follows:This utility model using the upper strata battery core setting gradually from top to bottom, in Between battery core and lower floor's battery core, positive pole upper strata lug and negative pole upper strata lug are provided with the battery core of upper strata, middle battery core set It is equipped with positive pole middle level lug and negative pole middle level lug, positive pole lower floor lug and negative pole lower floor lug are provided with lower floor's battery core; The length of positive pole upper strata lug is consistent with the length of positive pole lower floor lug, the length of positive pole upper strata lug>Lug in the middle of positive pole Length;Meanwhile, the length of negative pole upper strata lug is consistent with the length of negative pole lower floor lug, the length of negative pole upper strata lug>Negative pole The length of middle lug;The combination battery core of such lithium ion battery, can be prevented effectively from lug prewelding and excision technique, make pole Ear can be welded directly together, and can effectively shorten battery core production procedure, cuts down production process cost, improves business economic effect Benefit.
