Anode-Free Sodium-Ion Battery Startup Yin Gong Technology Raises 100 Million Yuan in Pre-A+ Round for GWh Production
news.metal.comYin Gong Technology, a Chinese startup developing anode-free sodium-ion batteries, has closed a Pre-A+ funding round at the 100 million yuan level. The round was co-led by Qifu Capital and the Fudan Science and Technology Innovation Fund, with participation from Suzhou Science and Technology Venture Capital, Xianghe Capital, and a global lead-acid battery manufacturer. The company's anode-free design eliminates the need for hard carbon on the anode side, potentially lowering costs while maintaining energy density comparable to lithium batteries. The funds will go toward building GWh-scale production lines and advancing product development across three battery series covering energy, power, and safety applications. The investor mix signals a shift in the sodium-ion battery space from broad speculation to targeted capital allocation. The involvement of a lead-acid battery giant suggests existing industrial players see sodium-ion as a direct replacement in light mobility and start-stop power markets. The Fudan Science and Technology Innovation Fund ties the company to university research pipelines, while regional state capital from Suzhou supports manufacturing expansion in the Yangtze River Delta. This financing round indicates the sodium-ion industry is moving past technology validation into volume production, with capital now favoring firms that combine differentiated chemistry, clear market pathways, and industrial partnerships.
