Enhanced cathode materials for advanced lithium-ion batteries using nickel-rich and lithium/manganese-rich LiNixMnyCozO2

Fossil fuel consumption raises the world's economy by causing severe ecological effects. Thus, contemplating an energy gadget with environmentally friendly behavior would be a desirable function. Furthermore, their advancement will aid in a dramatic increase in military resources and energy storage. Lithium-ion batteries paid more attention to offering high capacity and stability compared to other batteries. Specifically, the LiNixMny- CozO2(NMC) cathode achieves excellent specific capacity and cyclability, but with different effects like the deposition of residual lithium over the surface, ion mixing, oxygen release, dissolution of transition metal ions, and irreversible rock-salt phase transformation. Moreover, the idea of doping and coating will make the cathode efficient. The doping of materials like Al, Mg, Cr, and F makes an excellent stable cathode due to their strong bonding with oxygen atoms and also helps to increase the lattice parameter size during cycling for Li+ ion diffusion. Likewise, the coating covers the cathode surface and protects it from the electrolyte. Besides, there was no single counter to rectify all these drawbacks. Thus, the combination of two or more strategies can be a better idea to suppress these drawbacks and provide the NMC cathode with high stability, excellent cyclability, and rate capability for practical applications.

Automated summary

Fossil fuel consumption has severe ecological effects on the world economy, making it important to develop environmentally friendly energy devices. Lithium-ion batteries offer high capacity and stability, but face challenges such as residual lithium deposition, ion mixing, and oxygen release. Doping and coating techniques can improve the efficiency and stability of the cathode, but there is no single solution to address all the drawbacks, necessitating the combination of multiple strategies.
