Battery developer SES and ENTEK Membranes have announced an agreement to exclusively supply battery separation materials for the Apollo lithium metal hybrid battery cell recently unveiled by SES. The company is currently looking to expand as it plans to supply GM and Hyundai-Kia in the future.
SES (formerly SolidEnergy Systems) and ENTEK focus on their innovative approaches to the current business. Both also head offices in the United States, but said they share “a vision that is not limited by geography.” SES is headquartered in Boston with operations in Singapore and Seoul. The MIT spin-off recently announced plans for a production facility in Shanghai and is crucially awaiting deals with General Motors and Hyundai-Kia. The two automakers are also investors and customers who expect samples of the cells in 2022.
Scaling is therefore crucial, as SES chief technology officer Yongkyu Son said. “Increasing production is always a concern when bringing a new product to market, and the supply agreement with Entek Membranes helps us reduce supply chain issues while ensuring longer life for our batteries. lithium metal. He added that SES was “well positioned to fully commercialize its next-generation Li-Metal hybrid battery technology and build Giga-scale battery production.”
Said “hybrid battery” – so called because it combines solid and liquid components – bears the name of Apollo and was not unveiled until November. The idea, however, dates back to 2016, when the team was still at MIT working on a lithium metal battery in which the anode is replaced with an extremely thin lithium foil, which could dramatically increase energy density up to ‘at 500 Wh / kg. . Fast forward to Apollo, and the latest generation of this Li-metal battery boasts an energy density of 417 Wh / kg or 935 Wh / L for a weight of 0.982 kilograms and a capacity of 107 Ah – at room temperature. SES also claimed at the time that said performance was verified by two independent third-party test facilities and several car manufacturers.
Formerly known as SolidEnergy Systems, SES first announced this summer that it would go public in the United States by merging with Ivanhoe Capital Acquisition. The transaction is still waiting to be finalized. Besides General Motors and Hyundai-Kia, SES has also named Geely, SAIC, LG and Foxconn as potential investors.
ENTEK is headquartered in Lebanon, Oregon, with additional facilities in UK, Japan, Indonesia and China. The company has been active in the field of microporous polyethylene battery separators for 35 years.
None of the companies specified the scope of the transaction, ie production capacity or the value of expected transactions.
