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.
Lithium cobalt oxide (LiCoO 2, LCO) dominates in 3C (computer, communication, and consumer) electronics-based batteries with the merits of extraordinary volumetric and gravimetric energy density, high-voltage plateau, and facile synthesis.
While lithium cobalt oxide (LCO), discovered and applied in rechargeable LIBs first by Goodenough in the 1980s, is the most widely used cathode materials in the 3C industry owing to its easy synthesis, attractive volumetric energy density, and high operating potential [, , ].
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.
A rational compositional design of high-nickel, cobalt-free layered oxide materials for high-energy and low-cost lithium-ion batteries would be expected to further propel the widespread adoption of elec. vehicles (EVs), yet a compn. with satisfactory electrochem. properties has yet to emerge.
Nature Energy 3, 936–943 (2018) Cite this article Lithium cobalt oxides (LiCoO 2) possess a high theoretical specific capacity of 274 mAh g –1. However, cycling LiCoO 2 -based batteries to voltages greater than 4.35 V versus Li/Li + causes significant structural instability and severe capacity fade.

Understanding the Role of Cobalt in Batteries
One of the simplest cathode materials is lithium-cobalt-oxide (Li-Co-O 2) and he chose it as an example. "In a lithium-ion battery, what we are trying to do during charging is to take the lithium ions out of the oxide and intercalate, or insert them into a graphite electrode. During discharging, exactly the opposite happens," explained Abraham.
