About Jiangsu Yin Gong Technology

Jiangsu Yin Gong Technology (Yingong Technology, 隐功科技) is a Chinese new-energy company focused on the research, development, manufacturing, sales and service of sodium-ion batteries. It aims to deliver more cost-effective batteries and customised sodium battery solutions and to provide complete technical output for new-energy applications, and it promotes an anode-free sodium battery technology as its core differentiator, positioning itself as a leader in high-energy-density, affordable batteries.

Its cell product lines are the Yinfeng high-energy-density series, the Yinsu high-rate series and the Yinhu high-safety series. The high-energy cells use an anode-free architecture with soft-pack energy density above 190 Wh/kg, which the company says lowers manufacturing cost versus lithium batteries, while a cylindrical 18650 cell with high-rate and low-temperature performance is promoted as a strong option for motorcycle start-stop power.

Applications include consumer electronics, two-wheelers, power tools, engine start-stop power for motorcycles and passenger cars, and data center energy storage. The company has announced a joint development agreement with a major global automaker to apply anode-free sodium-ion batteries in passenger cars, which it describes as its entry into the passenger-car power battery market. It operates a headquarters and manufacturing base in Jiangsu, in Zhangjiagang, and an R&D centre in Shanghai, and publishes quality, certification and tender notices on its site.

Yin Gong sells battery cells and customised application solutions to equipment makers, vehicle makers and system integrators, with a business model of cell manufacturing plus co-development. It positions sodium-ion technology as a lower-cost, lower-risk alternative to lithium in light power and storage markets.
