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.
A “novel and innovative” technology which uses CO2 as a medium to store energy could be made using off-the-shelf equipment and made available to the market as early as next year, the company behind it has said.
An agreement has been signed which could lead to a multi-gigawatt lithium-ion battery cell manufacturing facility being built near Chennai, India, using 24M’s advanced ‘SemiSolid’ electrode technology.
A 2.5MW / 4MWh demonstration system using novel energy storage technology based on a “carbon dioxide battery” has begun construction in Sardinia, Italy.
