Ferroglobe PLC and Coreshel announced the signature of a memorandum of understanding. Together, Ferroglobe and Coreshell expect to produce the first battery-ready metallurgical silicon for the development of low-cost, high-range EV batteries in compliance with the U.S. Inflation Reduction Act. The partnership will enable the leapfrogging of silane-based silicon and the replacement of graphite in EV batteries, which have bottlenecked the auto industry since the introduction of electric vehicles, creating cost and range limitations.

Electric vehicles suffer from significant cost disadvantages for consumers and automakers alike, with batteries comprising 30-40% of the total cost of electric cars1. Car manufacturers are interested in using silicon in batteries because it can store up to 10 times more energy in the anodes than graphite. This could potentially result in a 30% increase in driving range.

Coreshell?s proprietary battery technology, featuring a unique nanomaterial electrode coating, is the only proven solution to mitigate the degradation of micrometric silicon, preventing its rapid loss of life while still allowing lithium ions to pass through. Ferroglobe?s proprietary metallurgical purification process to produce up to 99.995% silicon is cost-effective and does not use any chemical reagent, a key technology for producing affordable silicon active material. These innovations enable, for the first time, the development of lithium-ion batteries with metallurgical silicon dominant anodes that meet product requirements for lifetime across a range of applications.
