Abstract
The invention relates to a laminated lithium ion battery manufacturing method. The method includes steps: (1) selecting a plurality of diaphragms identical in size, and parallelly arraying the diaphragms on a same horizontal plane; (2) selecting a plurality of elongated positive plates and negative plates, and sequentially and alternately fixing the positive plates and the negative plates at intervals to surfaces of the diaphragms; (3) using a shearing device for shearing along two sides of the diaphragms to form a plate-diagram complex; (4) winding the plate-diagram complex to form a laminated lithium ion battery. The laminated lithium ion battery manufacturing method has the advantages that transferring frequency of the positive and negative plates and a battery unit comprising the positive and negative plates and the diaphragms is reduced, battery production procedures are reduced, battery production efficiency is greatly improved, battery production cost is reduced, and the laminated lithium ion battery manufacturing method has a guiding function in current battery production and manufacturing.
Description
Technical field
The present invention relates to lithium ion battery manufacture technology field, be specifically related to the manufacture method of a kind of laminated lithium ion battery.
Background technology
The advantages such as lithium ion battery has that energy density is high, has extended cycle life, self discharge is little, memory-less effect, since commercialization, of great interest with application.
At present the manufacture method of lithium ion battery mainly has takeup type and stacked two kinds.Coiled battery is that positive plate and negative plate are made continuous print sheet type, and centre is separated by barrier film, then makes battery roll core by the way of winding.There is the problem that stress is concentrated in this tradition coiled lithium ion battery, discharge and recharge the expansion of the pole piece caused and contraction long-term accumulated are likely to result in the deformation of pole piece, affect battery performance in the place that pole piece bends.
Positive/negative plate is mainly cut into monolithic by stack type lithium ion battery respectively, and barrier film is Z-shaped lap wound, and both positive and negative polarity monolithic intersects successively and stacks, and middle is separated by barrier film.Or positive plate, barrier film, negative plate are stacked composition battery cell successively, and battery cell bit combination on second layer barrier film again, second layer membrane coil it is coiled into battery roll core.Although stack type lithium ion battery improves the shortcoming during tradition coiled lithium ion battery makes, but there is the transfer of both positive and negative polarity monolithic or battery cell in laminated batteries, adds manufacturing process, affects production efficiency.
Summary of the invention
It is an object of the invention to provide the manufacture method of a kind of laminated lithium ion battery, to improve lithium ion battery production efficiency.
For achieving the above object, present invention employs techniques below scheme:
The manufacture method of a kind of laminated lithium ion battery, comprises the following steps:
(1) choose the barrier film that multiple size is identical, this barrier film is arranged in parallel within same level；
(2) choose positive plate and the negative plate of multiple strip, multiple positive plates and negative plate alternate intervals successively are fixed on membrane surface；
(3) carry out shearing formation pole piece-barrier film complex along the both sides of barrier film by shear；
(4) pole piece-barrier film complex is prepared as stack type lithium ion battery by winding.
Described positive plate and negative plate are respectively perpendicular the both sides being fixed on barrier film, and fixing after positive plate and negative plate in being alternately uniformly distributed.
Described positive pole monolithic, negative pole monolithic are interfixed by hot complex method with barrier film.
The width of described barrier film is more than positive plate or the width of negative plate.
Further, described barrier film width is more than positive plate or the 2～6cm of negative plate section.
As shown from the above technical solution, the manufacture method of laminated lithium ion battery of the present invention, by being positioned directly on barrier film after the cutting burst of both positive and negative polarity, the transfer of the battery unit decreasing positive/negative plate and include positive/negative plate and barrier film, decrease the operation of battery production, the efficiency of battery production is greatly improved, also reduces the cost of battery production simultaneously, current battery is manufactured there is directive function.
