Description

Lithium cell group of fast assembly

Technical Field

The utility model belongs to the technical field of lithium cell group and specifically relates to a fast assembly's lithium cell group is related to.

Background

Present lithium cell generally contains a N soft packet of unit, every soft packet of unit is laminated through the Z layer by a positive plate of M and a negative plate of M and is formed a unit (the quantity of M is between 10 ~ 140 pieces), every unit rethread plastic-aluminum shell membrane (need dash the hole in advance) encapsulates in advance, then when the equipment lithium cell, need paste a N soft packet of unit together through the double faced adhesive tape, form two total positive ears and negative pole ear with the utmost point ear welding of a N soft packet of unit together at last, the step is numerous, low in production efficiency, be difficult for assembling fast in lithium cell group, the lithium cell group of a fast assembly is proposed for this reason.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an it is not enough to overcome above-mentioned condition, aims at providing the technical scheme that can solve above-mentioned problem.

The utility model provides a fast assembly's lithium cell group, includes the group battery main part, the left side department electric connection on group battery main part top has anodal contact piece, and the right side department electric connection on group battery main part top has negative pole contact piece, the group battery main part includes Z style of calligraphy lamination, and Z style of calligraphy lamination is located the inside of group battery main part, the folding department on the inside top of Z style of calligraphy lamination is equipped with first negative pole piece, and the shaping of first negative pole piece top right side department has first negative pole utmost point ear, the folding department in the middle of Z style of calligraphy lamination is equipped with the positive plate, and the shaping of the left side department on positive plate top has anodal utmost point ear, the folding department of the inside bottom of Z style of calligraphy lamination is equipped with second negative pole piece, and the shaping of the right side department on second.

Preferably, the positive electrode tab is electrically connected to the positive electrode contact piece, and the first negative electrode tab and the second negative electrode tab are electrically connected to the negative electrode contact piece respectively, so as to perform power output and input of the battery pack main body.

Compared with the prior art, the beneficial effects of the utility model are that: positive and negative pole piece once only makes a big unit through Z layer stack, then encapsulates through the plastic-aluminum membrane (need not dash the hole), has saved the material of plastic-aluminum membrane and diaphragm greatly, has saved too much step, has increased the efficiency of lamination work, and the plastic-aluminum membrane need not dash the shell, has reduced numerous processes for lithium cell group rapid Assembly shaping.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
