Austin-based potassium-ion battery startup Group1 says its technology has comparable energy density to lithium iron phosphate (LFP), and that it is aiming for a large-scale launch of its product by 2027.
Startup Group1 is seeking to commercialise cathode materials for potassium-ion batteries, a world-first, while Northvolt is seeking to build batteries using a tree-derived carbon material lignin.
