SES AI Corporation, a global leader in the development and manufacturing of high-performance Li-Metal batteries for electric vehicles (EV) and other applications, provided insights into several exciting growth opportunities at its third annual Battery World event. These opportunities include: entering the world’s first B-sample Joint Development Agreement (JDA) with a major automotive OEM, a machine-based deep learning platform that will be utilized at its new Electrolyte Foundry, a new form-factor for its Li-Metal cells, and opportunities in the emerging Urban Air Mobility (UAM) market.
During the event, SES also commented on recently published 100Ah Li-Metal cell test data, honoring the tradition of keeping data transparency. The report shows great consistency of Li-Metal cell performance as they scale from small 4Ah to 50Ah and 100Ah. The 100Ah Li-Metal cells show excellent performance in cold weather and remarkable high-power performance. They also passed overcharge, nail penetration, external short circuit, and thermal stability tests conducted by third party and achieved UN38.3 certification.
“Safety is quality. As we build more large cells, we are also implementing an increasingly rigorous quality manufacturing system with full traceability to ensure practical safety. By collecting different types of data to train our AI-powered safety software Avatar, the prediction accuracy of our large Li-Metal cell health monitoring has increased from only 60% last year to 92% this year,” said Qichao Hu, SES Founder and CEO.

Deep learning for material exploration is also playing an increasingly important role in fundamental research and development. To speed up new material discovery, SES is building a machine-based deep learning platform which uses a graphical neural network model to process chemical structures and identify new promising candidates. The Electrolyte Foundry will be located near its corporate headquarters and will be dedicated to synthesizing and testing new electrolyte solvent molecules recommended both by human scientists and machines.
Apart from pouch cells, SES also displayed a new form factor, prismatic Li-Metal cells, to meet the diversified needs of OEMs. “Li-Metal has the highest gravimetric energy density among all battery chemistries and UAM is another perfect end-market for Li-Metal. We are now able to achieve more than 1500 cycles using C/3 charge and UAM mission profile discharge,” said Hu, “30 years ago, Sony introduced the first commercial Li-ion battery and changed consumer electronics forever. Now, SES plans to introduce the first commercial Li-Metal battery which could help accelerate urban air mobility.”
