Abstract
The utility model discloses a lithium ion battery cell consisting of one or more single battery cells, wherein, the single battery cell is made up of two or more complexes, each complex is made up ofan anode piece, diaphragm paper and a cathode piece laminated layer upon layer, bonding layers are arranged on two sides of the diaphragm paper, and the source of materials in preparing the bonding layers is either poly carboxylic tetrafluoroethylene or polyvinylidene fluoride. The lithium ion battery cell provided by the utility model is not subject to deformation when in service.
Description
Technical field
The utility model relates to field of batteries, relates in particular to a kind of lithium ion battery cell.
Background technology
But since lithium ion battery have voltage height, specific energy big, recycle long, good fast charging and discharging of security performance of life-span and operating temperature range advantages of higher, lithium ion battery has been applied to people's daily life field and national defence field more and more at large, the structure of general lithium ion battery is: be coated with electric core and organic electrolyte in the battery case, electric core is made up of positive pole, barrier film and negative pole.The shortcoming of existing lithium ion battery is that deformation can take place in use electric core, the lithium ion battery cell distortion can cause battery short circuit, lithium ion battery expands if distortion seriously can cause, cracking, sets off an explosion in discharge or charging process heat release, brings serious potential safety hazard to the user.
The utility model content
For addressing the above problem, main purpose of the present utility model is to provide a kind of lithium ion battery cell of deforming of in use being difficult for.
For addressing the above problem, the utility model adopts following structure:
A kind of lithium ion battery cell, form by one or more monomer electricity cores, described monomer electricity core is by being made up of two or more complexs, described complex is formed by positive plate, diaphragm paper and negative plate stacked arrangement and pressing, described diaphragm paper both sides have tack coat, and described tack coat adopts poly-carboxylic tetrafluoroethene or poly-inclined to one side fluorine divinyl as the preparation material.
The thickness of described tack coat is for being not more than 20 microns.
The thickness of described tack coat is 3 microns to 5 microns.
Composition mode between described monomer electricity core is in parallel or series connection.
The composition mode is stack or coiling between described complex.
Described positive plate adopts aluminium foil or aluminium net, applies positive active material in the one or both sides of described aluminium foil or aluminium net.
Described positive active material comprises lithium compound active material, conductive agent, bonding agent and solvent.
Described negative plate adopts Copper Foil or copper mesh, applies negative electrode active material in the one or both sides of described Copper Foil or copper mesh.
Described negative electrode active material comprises graphitic carbon material, conductive agent, bonding agent and solvent.
Lithium ion battery cell described in the utility model, form by a plurality of complexs, complex is formed by positive plate, diaphragm paper and negative plate stacked arrangement and pressing, the diaphragm paper both sides have tack coat, tack coat has bonding both positive and negative polarity and the fixedly effect of both positive and negative polarity, described complex is as a whole, its consistent, distortion unanimity that expands; Therefore described lithium-ion electric core has the consistent characteristics that expand, and therefore the local deformation that can effectively suppress lithium ion battery, can effectively suppress the varied in thickness of lithium ion battery on the whole, the consistency of control lithium ion battery.
