The use of cobalt in lithium-ion batteries (LIBs) traces back to the well-known LiCoO 2 (LCO) cathode, which offers high conductivity and stable structural stability throughout charge cycling.
In this manuscript it is shown as the presence of cobalt in Li-rich, layered oxide (LRLO) cathode materials is the main cause of the voltage and capacity fading, thus resulting detrimental for the long-term performance of lithium cells including it.
The development of high-energy Li-ion batteries is being geared towards cobalt-free cathodes because of economic and social–environmental concerns. Here the authors analyse the chemistry, thermodynamics and resource potential of these strategic transition metals, and propose that the use of cobalt will likely continue.
As seen in Figures 2 A and 2B , cobalt is by far the most valuable metal used in LIBs. In 2010, ∼25% of all cobalt produced was used in secondary batteries (LIBs and minor quantity in Ni-MH batteries), which grew to 30% in 2017 and is expected to expand to 53% by 2025 ( ).

Here we present a contrasting viewpoint. We show that cobalt’s thermodynamic stability in layered structures is essential in enabling access to higher energy densities without sacrificing performance or safety, effectively lowering battery costs per kWh despite increasing raw material costs.
