This mini-review discusses the recent trends in electrode materials for Li-ion batteries. Elemental doping and coatings have modified many of the commonly used electrode materials, which are used either as anode or cathode materials. This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
The active materials in the electrodes of commercial Li-ion batteries are usually graphitized carbons in the negative electrode and LiCoO 2 in the positive electrode. The electrolyte contains LiPF 6 and solvents that consist of mixtures of cyclic and linear carbonates.
The electrochemical reaction at the negative electrode in Li-ion batteries is represented by x Li + +6 C +x e − → Li x C 6 The Li + -ions in the electrolyte enter between the layer planes of graphite during charge (intercalation). The distance between the graphite layer planes expands by about 10% to accommodate the Li + -ions.
Lithium (Li) metal shows promise as a negative electrode for high-energy-density batteries, but challenges like dendritic Li deposits and low Coulombic efficiency hinder its widespread large-scale adoption.
Electrochemical performance parameters In Li-ion batteries, carbon particles are used in the negative electrode as the host for Li + -ion intercalation (or storage), and carbon is also utilized in the positive electrode to enhance its electronic conductivity.
