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.
Apart from these main components, there are other components such as a binder, flame retardant, gel precursor and electrolyte solvent . Lithium-ion batteries (LIBs) have been extensively used to supremacy a variety of moveable electronic devices because of their higher energy density and eco-friendly nature.
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.
Recent trends and prospects of anode materials for Li-ion batteries The high capacity (3860 mA h g −1 or 2061 mA h cm −3) and lower potential of reduction of −3.04 V vs primary reference electrode (standard hydrogen electrode: SHE) make the anode metal Li as significant compared to other metals , .
For Li-ion battery, crucial components are anode and cathode. Many of the recent attempts are focusing on formulating the electrodes with the elevated specific capability and cycling steadiness. In addition, efforts have been directed to prepare the electrodes via simple and facile methods.
