Now Cirba Solutions has formed a joint venture with 6K Inc., a global producer of sustainable materials for additive manufacturing and energy storage, to produce recycled battery cathodes.
6K harnesses a Massachusetts Institute of Technology-derived microwave plasma process that can produce a virtually infinite number of battery materials, faster, cleaner and at a lower cost than any other process, it says.
“6K’s UniMelt system replaces a less efficient chemical co-precipitation process with one that takes seconds and is powered by 6,000 degrees Kelvin microwave plasma,” 6K’s CEO Aaron Bent said in a release.
“Our partnership with Cirba Solutions allows us to leverage both companies’ capabilities to create a domestic supply chain that operates to insulate the United States from foreign shocks and supply chain disruptions while supplying next-generation battery materials,” Bent said.
The companies say the…
