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.
Many cathode materials were explored for the development of lithium-ion batteries. Among these developments, lithium cobalt oxide plays a vital role in the effective performance of lithium-ion batteries.
We predict that these techno-economic factors will drive the continued use of cobalt in nickel-based EV batteries. The development of high-energy Li-ion batteries is being geared towards cobalt-free cathodes because of economic and social–environmental concerns.
Currently, the commonly used positive electrode materials for lithium-ion batteries mainly include three types: lithium cobalt oxide, ternary materials, and lithium iron phosphate materials.
To replace the nickel and cobalt, which are limited resources and are assocd. with safety problems, in current lithium-ion batteries, high-capacity cathodes based on manganese would be particularly desirable owing to the low cost and high abundance of the metal, and the intrinsic stability of the Mn4+ oxidn. state.
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.

Positive electrode materials in a lithium-ion battery play an important role in determining capacity, rate performance, cost, and safety. In this chapter, the structure, chemistry, thermodynamics, phase transition theory, and stability of three metal oxide positive materials (layered, spinel, and olivine oxides) are discussed in detail.

Subsequently, the insertion of lithium into a significant number of other materials including V 2 O 5, LiV 3 O 8, and V 6 O 13 was investigated in many laboratories.
