The transition towards a sustainable energy eco-system with e-mobility and renewable energy integrated power grids require efficient energy storage solutions. As of now the most promising candidate of choice has been the Lithium-ion battery (LIB) chemistry, in which, a graphite anode is paired with a lithium cobalt oxide cathode, offering high energy density. However, LIBs are known to have a price challenge along with another serious challenge, the availability of raw materials for battery manufacturing. Battery manufacturing typically requires lithium, nickel, magnesium, and cobalt amongst other metals. Cobalt, in particular, is a matter of concern for battery and EV manufacturers due to Cobalt's vulnerability to a fragile global supply chain.

Battery manufacturers across the globe are continuously working towards the development of cobalt-free battery chemistries, and are also utilizing data-driven methods to identify and fabricate materials which have the potential to substitute cobalt in battery chemistries.
This research, ‘Emerging Innovations Enabling Cobalt-free Batteries’ focuses on the emerging innovations and the latest achievements in the cobalt-free battery chemistries and the respective technology readiness levels. In addition to above, recent trends and developments across the industry, government-level initiatives supporting research & development activities, along with the challenges present in the global cobalt supply chain is also provided.
