Future research directions on porous materials as negative electrodes of LIBs were also provided. Lithium-ion batteries have revolutionized the portable electronics market, and they are being intensively pursued nowadays for transportation and stationary storage of renewable energies such as solar and wind.
This review critically discusses various aspects of commercial electrode materials in Li-ion batteries. The modern day commercial Li-ion battery was first envisioned by Prof. Goodenough in the form of the LCO chemistry. The LiB was first commercialized by Sony in 1991. It had a LCO cathode and a soft carbon anode.
In this review, porous materials as negative electrode of lithium-ion batteries are highlighted. At first, the challenge of lithium-ion batteries is discussed briefly. Secondly, the advantages and disadvantages of nanoporous materials were elucidated. Future research directions on porous materials as negative electrodes of LIBs were also provided.
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.
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.
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.
