Key Points

Investigate the structural and electrochemical impacts of replacing manganese with magnesium in LiNi0.6Co0.2Mn0.2O2 cathode materials for lithium-ion batteries.
Synthesized and experimentally tested LiNi0.6Co0.2Mn0.2−xMgxO2 cathode formulations across varying magnesium substitution levels.
Performed ab initio first-principles calculations to model the electronic and structural effects of magnesium substitution.
Determined that magnesium substitution alters the crystalline structure and local atomic configuration of the nickel-based cathode material.
Showed that incorporating magnesium modifies the electrochemical reaction behavior and structural stability during battery operation.

Implication

Experimental and computational modeling demonstrates the effects of magnesium doping in nickel-rich cathodes, highlighting structural strategies to enhance lithium-ion battery stability.
