SES AI Becomes First to Pass China’s Safety Tests For 100 Ah Li-Metal EV Batteries

SES AI announced a new milestone that its 100 Ah Li-Metal cells have become the first to successfully pass the stringent safety tests mandated by China’s GB38031-2020 Electric Vehicles Traction Battery Safety Standard.

SES AI’s successfully passing the stringent safety tests marks a new step forward in the commercialization of Li-Metal battery technology for EVs and urban air mobility (UAM) applications. The GB38031-2020 standard, which is mandatory in China includes a series of rigorous tests designed to ensure batteries can effectively manage safety risks under extreme conditions.

Qichao Hu, Founder and CEO of SES AI, expressed the company passing the safety tests stating, “The results are highly encouraging, affirming our decade-long commitment to refining Li-Metal chemistry and enhancing the safety of Li-Metal batteries. It’s also the first time in the industry that a high energy density cell such as Li-Metal passes the rigorous safety tests of GB38031-2020.”

The comprehensive safety tests include overcharge, over-discharge, external short circuit, heating, temperature cycling, and crushing scenarios. Passing these tests not only displays SES AI’s goal for safety but also strengthens its position in advanced battery technology within the EV industry.

Notably, this milestone follows SES AI’s earlier success in acquiring the UN38.3 safety certificate last year. Moreover, the company has also introduced an AI for Safety system capable of predicting and preventing nearly 100% of safety incidents in the field.

Recently, SES AI partnered with Hyundai and Kia regarding its existing joint development agreement (JDA) by moving into its next phase of developing B samples. This progress makes SES AI the only Li-Metal battery company with two automotive B-sample agreements in progress, bolstering its commercialization efforts.
