Foshan Plastic Technology (000973.SZ) has announced its intention to form a joint venture by investing 100 million yuan alongside Zijin Lithium Yuan (a subsidiary of Zijin Mining), Xiamen Zijin, and the affiliated entity Guangxin Research Institute. The newly established project company will channel 113.39 million yuan into the development of a pilot-scale platform dedicated to the production of battery-grade lithium sulfide. This initiative encompasses the construction of a lithium sulfide production line with an annual capacity of 100 tons, focusing on the research, development, manufacture, and marketing of high-purity battery-grade lithium sulfide products. Foshan Plastic Technology will contribute 5 million yuan to this venture, securing a 5% equity stake in the project company. As this investment involves a related-party transaction, it is anticipated to exert a minimal influence on the company's future financial performance and operational outcomes.
