Description

A kind of casing of lithium ion battery
Technical field
The utility model relates to lithium ion battery, particularly a kind of shell for encapsulation of lithium ion battery.
Background technology
Lithium battery is as rechargeable battery product of new generation and traditional lead-acid battery, NI-G, Ni-MH battery compare have the voltage height, energy density is large, have extended cycle life, memory-less effect and the characteristics such as pollution-free, it is that energy density is the highest in all secondary cells, the battery that cycle life is the longest.Lithium ion battery has just surmounted rapidly other secondary cell products such as Ni-MH battery, NI-G, lead-acid battery within the short more than ten years, can be widely used in the power station mobile phone, notebook computer, digital camera, electric motor car, electric tool, solar power generation, wind power generation, poultry.
Plastic lithium-ion battery can solve Insulation Problems in the battery pack connection in series-parallel process and the technical security problem in the high-pressure type battery combination process, but the composite engineering plastics that adopts at present can't satisfy Production requirement in welding method and effect, and the batch production of plastic battery is produced and also just stopped at present theory stage.Welding is main adopts hot plate welding, ultrasonic bonding, because plastics shrink problem, causes in welding process the commissure resistance to compression inadequate, and the later stage is prone to the breach phenomenon.Original technology also is added with the fillers such as glass fibre, asbestos in plastics, these fillers have not only strengthened the difficulty of welding, also cause the little seepage of battery later stage inside battery liquid.
The utility model content
The purpose of this utility model is the defects for prior art, and a kind of shell for encapsulation of lithium ion battery is provided.
For solving the defects of prior art, technical scheme to be solved in the utility model is: a kind of casing of lithium ion battery, comprise housing and cap, described housing has an opening, be provided with the first flange at the edge of described opening, the upper and lower surface of described housing all is interval with many grooves, described cap has upper surface and lower surface, described upper surface one end is provided with anodal mount pad, the other end of described upper surface is provided with the negative pole mount pad, the position of the corresponding described anodal mount pad of described lower surface is provided with cathode contact, the position of the corresponding described negative pole mount pad of described lower surface is provided with cathode contact, described lower surface edge is provided with the first groove, and described the first groove inward flange extends outward the second flange, and described the first groove is connected with described the first flange.
As a kind of improvement of the utility model casing of lithium ion battery, described anodal mount pad and described negative pole mount pad middle part are respectively equipped with the second groove.
As a kind of improvement of the utility model casing of lithium ion battery, be provided with a counterbore between described anodal mount pad and the described negative pole mount pad.
As a kind of improvement of the utility model casing of lithium ion battery, described housing and described cap are plastic rubber component.
Compared with prior art, the utility model has the advantages that: housing and cap that the utility model adopts plastic member to make, advantage with airtight intensity height and long service life after resistance to acids and bases, corrosion resistance, the welding, and adopt the first groove to be connected with the first flange, weld again after the connection, prevent solution leakage; The utility model is simple in structure, and crushing resistance is strong.
