Description
Technical field
The utility model relates to the lithium ion plastic battery, particularly a kind of shell cover structure of lithium 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.
