Currently, the high cost of batteries is the main obstacle to EVs. While materials such as silicon provide significant increases in capacity over commonly used graphite anodes, they also have their limitations.
Problem? During charging, silicon anodes swell significantly, which leads to deterioration of the structure and reduced service life.
Coreshell’s development solves this problem by using silicon anodes with special metallurgical grade coating. This approach offers several advantages. Metallurgical grade silicon is significantly less expensive than commonly used options, and is even cheaper than graphite. The coating allows the silicon to expand and contract during charge cycles without degradation, which extends battery life.
Unlike graphite, whose supply chain is dominated by China, metallurgical grade silicon is more widely available worldwide. The company plans to combine silicon anodes with lithium iron phosphate (LFP) cathodes.
Coreshell technology, while promising, is still in its infancy.
