Abstract
The utility model relates to a lithium ion multi-winding-core power battery, mainly comprising a positive piece (1), a negative piece (2), diaphragms (3), electrolyte and an aluminium-plastic shell (5). The lithium ion multi-winding-core power battery is characterized in that the positive piece (1), the diaphragm (3), the negative piece (2) and the diaphragm (3) which have equal length are distributed at intervals and are wound into naked electric cores (9); two or more naked electric cores are placed in the same aluminium-plastic shell (5), and pole lugs (4) of a plurality of positive electrodes are connected together with nickel pieces (6) so as to be used as the positive electrode of the battery; and pole lugs (4) of a plurality of negative electrodes are connected together with nickel pieces (6) so as to be used as the negative electrode of the battery. The lithium ion multi-winding-core power battery overcomes the defects that the pole pieces of the existing single large-capacity battery are too long so as to be difficultly wound or not to be wound, and the laminating technique is low in efficiency. The lithium ion multi-winding-core power battery is realized by dividing the positive piece, the negative piece and the diaphragms into a plurality of sections with equal length so as to be wound into a plurality of winding cores, and arranging the plurality of winding cores in one aluminium-plastic shell. The utility model forms large capacity of single lithium ion multi-winding-core power battery, and is high in production efficiency.
Description
Technical field
The utility model relates to a kind of polymer Li-ion battery, and more particularly it is a kind of lithium ion multireel core power battery.
Background technology
The world today is because of environmental protection and requirements of saving energy, and the energy of seeking high efficiency and environmental protection is more and more urgent, seeks the inexorable trend that novel power source becomes social development and scientific progress.The electrokinetic cell of current use is mainly lead-acid battery, Ni-MH battery, lithium ion battery.And lithium ion battery becomes the ideal source of electric motor car because of characteristics such as its specific power height, cycle life are long.
Existing lithium ion battery extensively adopts positive and negative electrode film, barrier film, assembles by coiling, lamination technology, adds liquid electrolyte then.The battery of producing, it is little to have energy density height, output voltage height, self discharge, and characteristics such as cycle performance is superior, at present because the development of industries such as electric bicycle, electric automobile just need lithium electricity monomer high capacity, and conventional winding process battery all is the monovolume core, make the big capacity of monomer, because the long very difficult coiling of pole piece, lamination technology can realize, but production efficiency is very low again.Therefore, research and develop a kind of lithium ion multireel core power battery and become an important and urgent job.
Summary of the invention
The purpose of this utility model is to overcome the long very difficult coiling of existing monomer high capacity cell pole piece, and the deficiency that the lamination process efficiency is very low, and a kind of lithium ion multireel core power battery that provides maybe can not be provided.
The purpose of this utility model is achieved through the following technical solutions: lithium ion multireel core power battery, it mainly is made up of positive plate, negative plate, barrier film, electrolyte, plastic-aluminum shell, it is characterized in that it is isometric positive plate, barrier film, negative plate, barrier film to be arranged at interval be wound into naked electric core, naked electric core more than two or two is put into same plastic-aluminum shell, and the lug of a plurality of positive poles connected together with the nickel sheet, as the positive pole of battery; The lug of a plurality of negative poles connects together with the nickel sheet, as the negative pole of battery.
In technique scheme, described positive plate and negative plate are formed by coating materials district, lug weld zone, lug, and lug is welded on the lug weld zone.
The utility model is that long positive plate, negative plate, barrier film are divided into a plurality of isometric section, is rolled into a plurality of volume cores, a plurality of volume cores is installed in the plastic-aluminum shell realize.It has formed the high capacity of lithium electricity monomer, has overcome the problem of the long very difficult coiling of pole piece, and lamination technology is simple, the production efficiency height.
