Freudenberg vliesstoffe se & Co. kg, one of the largest battery membrane manufacturers in the world, signed a strategic cooperation agreement with our company, and the two sides established a "nickel zinc diaphragm (China) test center of Germany vliesstoffe company" in BPI company. This will further promote BPI to take the lead in product R & D and production, and continue to maintain its competitive advantage.

Nickel zinc battery is called the 5th generation rechargeable battery. Its main characteristics are 1.6V high voltage, which is higher than 1.2V of nickel hydrogen and nickel cadmium batteries, and 1.5V of primary alkaline batteries. In addition, it has the excellent characteristics of sustainable high current discharge, a wider source of zinc raw materials and a lower price. It is an ideal battery to replace primary dry batteries and nickel cadmium batteries. In the long-term production, many technical personnel have been puzzled by the characteristics that zinc is easy to dissolve in the electrolyte and the high proportion of low pressure caused by dendrite phenomenon. Now, through cooperation with koderberg, we have jointly developed a high-performance special diaphragm for nickel zinc battery, which will effectively solve the dendrite problem, make the reliability of mass production of nickel zinc battery higher, and supply it to well-known customers in Europe and America.
With many years of experience in the field of diaphragm and a very perfect service network, the company has been developing and making progress in the Chinese market. It has been cooperating closely with BPI since the establishment of the plant. Kedebao company recognizes BPI's technical advantages in the manufacturing and R & D of domestic nickel zinc battery cells, and greatly affirms BPI's systematic and rigorous operation and management.
Both parties jointly set up a "nickel zinc diaphragm (China) test center of Germany Goldberg company" in Shenzhen BPI Battery Co., Ltd., and Goldberg provides corresponding product resources and technical support to BPI battery company. BPI is responsible for the performance test of its newly developed nickel zinc battery diaphragm and providing a written report to Fort COD for reference and improvement. The interactive cooperation mode realizes the goal of win-win for all parties, and also lays a foundation for BPI to better and faster respond to market demand and serve customers.
