Nickel sulfate—a crucial component of the nickel industry chain—is the core raw material that supports the development of new energy vehicle power batteries, electroplating, and other fields in China. Its industry development trends and technological development directions regarding raw material production, smelting, processing, and recycling have attracted much attention. In this paper, we summarize the current status of nickel sulfate production and technology in China, and analyze the major problems faced by China’s nickel sulfate industry, including inadequate supply of raw materials, high carbon emission intensity, and a deficient recycling system. Moreover, we analyze the development trends and propose the development ideas and goals for the industry by 2035. Furthermore, we propose the following countermeasures for promoting the sustainable development of the industry: (1) establishing an efficient supply system to promote the diversified supply of raw materials; (2) encouraging technological innovation to reduce production costs and supply pressure; (3) accelerating the development of the regenerated nickel industry to promote the consumption of regenerated nickel; and (4) accelerating the internationalization and industrial integration of Chinese enterprises to enhance their core competitiveness.
