LR1130 battery aluminum-plastic film production technology has advantages
At present, there are two main production processes for aluminum-plastic films for lithium batteries at home and abroad: the dry production process represented by Japan's Showa and the thermal production process represented by Japan's DNP.
The dry production process was jointly developed by Japan Showa and Japan's Sony. Since Sony's electrolyte is solid and does not require the electrolyte resistance of the aluminum-plastic film, Japan's Showa's dry process uses an adhesive, and the adhesive The electrolysis resistance is relatively poor, which affects the service life of the lithium battery aluminum-plastic film to a certain extent. The thermal production process is an aluminum-plastic film product jointly developed by Japan's DNP and Japan's Nissan to produce automotive batteries. It is better than Japan Showa in terms of electrolysis resistance.
Japan's Fujimori lithium battery aluminum plastic film production process also uses Japan's DNP's thermal technology. In 2011, Japan's Fujimori began to enter the Chinese market. However, at present, Japan's Fujimori products cannot be used to export battery cells. The main reason is that the technology is copied from Japan's DNP, and export products will be restricted by patents.
At present, the aluminum-plastic film produced by domestic enterprises is mainly used to produce lithium batteries for digital products, mainly due to technical limitations. At present, domestically produced aluminum-plastic films have a short research and development time and unstable product quality. Therefore, domestic lithium battery manufacturers have not adopted domestically produced aluminum-plastic films on a large scale.
1. Japan Showa lithium battery aluminum plastic film production process
ShowadenkoALF was jointly developed and launched with Sony Corporation of Japan in 1999. In 2001, it was led by Showa Denko and the second generation aluminum-plastic film was launched. In 2003, it was promoted in the Chinese mainland market. Currently, showadenkoALF is in the polymer lithium-ion battery market. Occupy an important market share.
As the world's largest manufacturer of polymer lithium-ion battery materials with the most complete range, Showa Aluminum Plastic Film has absolute advantages in terms of raw material quality stability, supply sustainability, and R&D technology.
The advantages of Showa aluminum plastic film are: low cost, fast delivery; smooth and flat appearance, no trachoma or wrinkles; good punching performance, which can meet the requirements of most polymer lithium ion batteries (matching Showa punching equipment for punching up to 8~10mm); heat sealing performance; under appropriate temperature, pressure, and time conditions, the sealing strength, sealing insulation, and sealing performance of Showa Aluminum Plastic Film are far superior to similar products; electrolyte resistance, Showa Aluminum Plastic Film The inner layer of the membrane is high-purity CPP, which has good resistance to electrolyte corrosion. Showa Denko's aluminum-plastic films are widely used in polymer lithium-ion batteries such as MP3 players, mobile phones, tablet computers, PDAs, model aircraft, UPS, and electric bicycles.
2. Japan’s DNP lithium battery aluminum plastic film production process
Japan's DNP aluminum plastic film production technology has been developed since 2001, and is similar to the dry production method adopted by Japan's Showa.
It can be seen from the structural diagrams of the two production processes of dry method and thermal method that the main difference between thermal method and dry method is that thermal method uses MPP in the production process. MPP is a modified PP, also called acidic. PP and MPP have high thermal bonding properties, so in the production of lithium battery aluminum-plastic films, adhesives do not need to be used between the aluminum foil layer and the CPP film.
