Polymer lithium-ion batteries in 1999, Japan took the lead in industrialization. China has also started the production, such as Xiamen Baolong Battery Co., Ltd. and Guangdong Huizhou TCL King to Battery Co., Ltd. has begun production. At present the company for the production of polymer lithium-ion battery is not exactly the same route, and these companies are not to be too much of these technologies open. The following techniques on a number of public explanation.

The first open for Bellcore (now changed to Telcordia) company, its production processes to indicate. Thinkpad T400 battery(14 inch) Collector, respectively, AI Network (positive)) and Cu Network (negative). Through the heat roller, will increase plasticized PVDF-HFP polymer melt, and then sandwiched between electrodes, as a component. And then placed in an organic solvent component, the plasticizer (for example, dibutyl phthalate) soak up, then Package A1 layer in a plastic bag, vacuum heating, and then into the electrolyte, the formation of gel. The most important processes are as follows: ① the pretreatment of electrode material and electrode paste mixing process; ② membrane electrode system, cutting process; ③ single cells (Bicell) of the assembly process; ④ cell formation process.

As the polymer lithium-ion batteries with liquid electrolyte lithium-ion battery compared to the major difference is that membrane and electrolyte. Therefore, the electrode materials and preparation process is basically the same as the liquid electrolyte (of course, can also be little change). The main difference is the battery electrolyte membrane and the assembly process. Of course, pavilion dv9000 battery as the liquid electrolyte lithium-ion battery, as in the assembly process, the environment is an important quality assurance dehumidifying conditions.

In terms of the company’s process for Bellcire, it is relatively complex and there are some residual solvent, a great impact on product performance. Therefore price is high, in the actual production process is rarely used.

Sony, Sanyo, Motorola, Polystore companies, international companies are also carrying out research in this area. For example, Sanyo porous polyethylene membrane of the basis of the PEO precursor and plasticizer, and then PEO precursor to polymerization. The shortcomings of the Act is the precursor of the polymerization of ethylene oxide is not complete, a small amount of residual monomer, affecting electrochemical performance. If the use of heating method can shorten the reaction time, Satellite A50 battery but on the negative membrane.

Sony 80 in the late 20th century started on lithium-ion polymer battery. Of course, was not the term polymer lithium-ion batteries, mainly PVDF – HFP of block copolymers as a gel carrier, the amount can be as low as 3% to 7.5% (mass). Organic electrolyte plus a PC, a very negative PC has good compatibility with the modified graphite.
