Yunnan Enjie Co., Ltd. signed a strategic cooperation agreement to jointly produce solid electrolyte coating diaphragms and other products.

On October 21, 2021, Shanghai Enjie New material Technology Co., Ltd. (hereinafter referred to as "Shanghai Enjie"), the controlling subsidiary of Yunnan Enjie New material Co., Ltd. (hereinafter referred to as "Shanghai Enjie") and Beijing Weilan New Energy Technology Co., Ltd. (hereinafter referred to as "Weilan New Energy"), Liyang Tianmu pilot Battery material Technology Co., Ltd. (hereinafter referred to as "Tianmu pilot") signed the Strategic Cooperation Framework Agreement in Shanghai. The three parties have reached a strategic partnership in the future research and development of new technologies, new products, new processes and the realization of cooperation goals, and jointly set up a solid electrolyte coating diaphragm company to jointly develop and produce coating diaphragms and specially customized coating diaphragms. The joint venture is controlled by Shanghai Enjie, which is 51% owned by Shanghai Enjie, 25% by Weilan New Energy and 24% by Tianmu Leader. In the future, the joint venture will give priority to supplying goods to Weilan New Energy and its subsidiaries.

The three parties will introduce their own new technologies, new processes, new products and intellectual property rights into the joint venture company, jointly develop and develop in the field of semi-solid and solid-state lithium-ion batteries, systematically combine the base membrane with solid-state electrolyte coatings, and develop and produce solid-state electrolyte coating separators and specially customized coating separators. With the goal of establishing the core supplier status of special ion conductor composite diaphragm in the new energy vehicle supply chain, energy storage industry chain and consumer electronics industry chain, we will actively promote industrial technological innovation.

The company is the leader in the global lithium battery isolation membrane industry, and has laid out production bases in Shanghai, Zhuhai, Jiangxi, Wuxi, Suzhou, Chongqing, Changzhou and overseas Hungary, ranking first in the world in terms of production capacity, shipments and market share. with many well-known lithium battery manufacturers at home and abroad to maintain long-term and stable cooperative relations, significant cost advantages, strong technical research and development strength. In recent years, the new energy vehicle industry has developed vigorously, and the technological innovation of lithium battery has also received widespread attention. the company's research institute has already set up a new battery material research institute to actively pay attention to and study various new materials and cutting-edge technology. to ensure that the company maintains a leading competitive advantage in the development of the industry. In April this year, Zhuhai Enjie New material Technology Co., Ltd., a wholly-owned subsidiary of Shanghai Enjie, cooperated with Shenzhen Institute of Advanced Technology of the Chinese Academy of Sciences to establish the China Kekejie Battery Frontier Materials Technology Joint Lab to carry out in-depth cooperation in the fields of quasi-solid electrolyte and its composite separator materials, flexible solid-state battery technology, sodium ion battery and its separator technology and battery development, to help the company enhance its R & D strength.

Weilan New Energy focuses on mixed solid-liquid electrolyte batteries and all-solid-state battery products with high energy density, high safety, high power, wide temperature range and long life, and breaks through existing technological bottlenecks through original innovation. the application covers new energy vehicles and ships, large-scale energy storage, 3C consumption, other industries and other industries, and has a number of solid-state battery core patents. It is the only industrialization platform of solid-state battery technology in the Clean Energy Laboratory of Institute of Physics, Chinese Academy of Sciences.

Tianmu forerunner is a high-tech enterprise specializing in the research, development, production and sales of new nano-silicon-carbon anode materials for lithium-ion batteries, with the world's earliest core patents for nano-silicon-carbon anodes, including more than 10 core patents for the composition, structure, manufacture and application of silicon anode materials.

This time, Shanghai Enjie hand in hand with Weilan New Energy and Tianmu forerunner can further expand the research and development depth of the company's diaphragm in semi-solid and solid-state batteries, accelerate the industrialization process with partners, and lead the industry development with scientific and technological innovation. continue to enhance the company's core competitiveness.
