SMM has learned that General Motors has recently partnered with a US battery recycling firm to supply both new and used EV batteries for second-life energy storage applications. This collaboration builds on GM's prior success in powering a 2,000-GPU data center through a 12MW/63MWh microgrid project using repurposed batteries.
The recycling company's energy storage division, which specializes in converting retired EV batteries into grid-scale storage systems, discovered through testing that many used batteries retain significant usable life. Instead of dismantling them for material recovery, the company directly repurposes entire battery packs through cascade utilization.
Currently handling approximately 70% of America's spent EV batteries, the company aims to deploy 20GWh of energy storage capacity by 2028. Its co-founder noted that this second-life business may eventually surpass their core recycling operations in growth potential.
