March 19-21, 2021, the 14th China International Battery Technology Exchange Conference/Exhibition（CIBF 2021）was held in Shenzhen Convention and Exhibition Center. CIBF is a regular meeting of battery industry sponsored by China Chemical and Physical Power Industry Association, which is held every two years. The exhibition focuses on global power batteries, energy storage batteries, 3C batteries, various battery materials, manufacturing equipment, power and energy storage system solutions. In this exhibition, Shanghai Weikai Optoelectronics New Materials Co., Ltd. (hereinafter referred to as "Weikai Optoelectronics") showed li-ion flexible packaging and aluminum plastic film adhesive overall solution.
Through the unique formula design and process optimization, the series products of lithium-electric aluminum plastic film adhesive have a wide range of versatility and outstanding performance.
（1）Secondary adhesive VN series
Secondary adhesive VN series include high performance VN930 and general typeVN830. Match with hardener CA-N6, is suitable for PA, PET, aluminum foil and other substrates. With high bonding strength, humidity and heat resistance, and heat resistance as well as the resistance to deep drawing, the general-purpose type is suitable for 3C lithium batteries.
（2）Primary adhesive VP series
Primary adhesive VP series include high performance VP118 and general type VP318. Match with hardener CA-P2 and bond with Al/CPP, it has high bonding strength, heat and humidity resistance, heat resistance and deep drawing resistance. Among them, the high performance is suitable for power lithium batteries, and the general type is suitable for 3C electronic lithium batteries.
（3）Aluminum foil passivation treatment agent VB series
Aluminum foil passivation solution is trivalent chromium type aluminum foil surface treatment agent, in which VB108 is suitable for dry passivation, VB208 is suitable for thermal passivation. The two technologies are different in application, but both have excellent corrosion resistance, which can not only improve the electrolyte resistance of aluminum foil, but also improve the bonding strength with the adhesive, especially for the passivation treatment of lithium battery for soft package aluminum plastic film.
In this exhibition, WEIKAI Optoelectronics, as a supplier of aluminum plastic film adhesives for lithium batteries, has received close attention from upstream and downstream visitors in the lithium battery industry. During the exhibition, the booth communication and negotiation atmosphere is active.
As the pace of domestic electric process keeps accelerating, the new energy industry is flourishing, WEIKAI keeps up with the trend of the times, adheres to independent research and development, solved the technical bottleneck of aluminum-plastic film adhesive which dependents on imports, is the interpretation for 14th Five Year Planplanning of “Accelerate the construction of a new development pattern in which the domestic big cycle is the main body and the domestic with international double cycles promote each other".
WEIKAI adheres to paying care to our customers. By providing fast response and high-quality services, we can always meet the various needs of customers in time.WEIKAI not only provides technical support for adhesive products, but also relies on the company's strong R&D and technological innovation to provide technological solutions based on the needs of customers. In the future, WEIKAI will adhere to the goal of serving customers and contribute to the development of the lithium battery industry.
