New material of Mingguan, Xie Hui – the guarantee of core technology breakthrough and safety performance of domestic aluminum plastic film

On the one hand, the world's new energy automobile is booming; On the other hand, power battery has the requirement of high energy density. Under this background, soft package battery is foreseeable in the field of power.

The personage inside course of study is generally believed that the domestic soft package the battery has become one of mainstream power battery development route, the future of soft package battery industry chain is expected to enjoy industry rapid development and permeability multiple pull ascend, localization of alternative.

May 21, with "safety, industry change phenomenon in enterprise stratification stability rushes to" as the theme of the 11th high lithium electricity industry summit held in Shenzhen four seasons hotel grand. As lithium electricity industry the authority of the platform, the summit attracted materials, equipment, batteries, BMS, PACK, such as the new energy automotive industry chain of the entire vehicle exceeds 800 executives involved.

Summit, Ming crown new materials co., LTD. (hereinafter referred to as "new material" Ming crown) fancy researcher/senior technical engineers Tse-fai published the theme of "homebred aluminous model membrane core technology breakthrough and safety performance guarantee" excellent speech.

Tse-fai said, aluminum-plastic film ballooning, layered, corrosion, bad appearance form is the important factor of influencing the soft package security. Currently, aluminum-plastic film dry process while deep impact performance is good, simple process, low cost, but there are weak electrolyte resistance and water resistance of weaknesses. And thermal method process although electrolyte resistance and water resistance is good, but again there is a rush about the worse performance of deep faults.

Ming crown new materials aluminum-plastic film with many years accumulation in high-performance adhesive, independent research and development of dry complex legal, in terms of the advantage of dry process, both the thermal process in electrolyte resistance and water resistance of the advantages of characteristic, make aluminum-plastic film on deep forming, appearance is poor, poor cutting performance, resistance to electrolyte and resistance performance of comprehensive improved its comprehensive performance.

"Water, insulation, corrosion resistance, resistance to friction and compound is the five factors influencing the aluminum-plastic film performance, and homebred aluminous model membrane performance breakthrough five direction." Tse-fai said.

Ming crown new material aluminum membrane in unique ways, the water vapor transmittance 100 PPM / 7 days or less; In terms of friction resistance, company mature PET composite technology, makes the aluminum-plastic film resistance to washing and friction.

In terms of insulation, corrosion resistance, external structure of PET, surface corrosion resistance of the electrolyte can be resistance to electrolyte pollution over 24 h, basically eliminated the electrolyte pollution; High insulation after the 1000 v direct current click 500 seconds G Ω levels remain the same. Internal with unique modified CPP, effectively reduce the resistance of scrap rate.

At the same time, the company USES the independent research and development of composite structure of PP, the aluminum foil corrosion coating and special, electrolyte resistance adhesives three electrolyte layer of protection make it difficult to invade to aluminum foil, aluminum foil layer corrosion protection of aluminum membrane integrity, and has a long-term stability of the electrolyte resistance performance.

Lu: Su Ming crown new material in compound membrane also has obvious competitive advantage, the diagram below:

Thanks to the company for many years in the field of aluminum composite membrane technology accumulation and domestically produced aluminum-plastic film market demand break nears, Ming crown has days trouble with new energy, new material dynamic power lithium and lithium electricity companies signed a long-term cooperation agreement. To cope with the growth of the market scale, Ming crown aluminum-plastic film has 50 million/year supply capacity is being made now.

Learned, Ming crown new materials was established in 2007, is a focus on new energy field of advanced materials research and development and manufacturing of national high and new technology enterprise. Main products include solar battery back and the lithium battery Lu: su film, focused on more than 10 years of production of composite membrane material.

Ming crown believes that new materials, soft package once battery market really started, possess the core technology strength of the domestic aluminum composite membrane manufacturers will be an important variable, participate in market competition and challenge technology, technology upgrade will also become a powerful position of Ming crown and win the market.
