Cobalt is necessary for the production of the most common types of lithium-ion batteries (Li-ion), like the rechargeable ones used to power our portable electronic devices and electric vehicles. The transition to electric mobility is widening the gap between supply and demand and increasing the price of cobalt. However, substitution of cobalt in Li-ion batteries, although possible, has not taken place. The EU-funded COBRA project aims to reverse this situation. It is developing a cobalt-free cathode with the participation of three universities and seven research and technology organisations as well as four SMEs and five enterprises, covering the entire value chain of the EU battery industry.
