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.
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 , .
Summary and Perspectives As the energy densities, operating voltages, safety, and lifetime of Li batteries are mainly determined by electrode materials, much attention has been paid on the research of electrode materials.
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.
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.
This has led to the high diffusivity of Li ions, ionic mobility and conductivity apart from specific capacity. Many of the newly reported electrode materials have been found to deliver a better performance, which has been analyzed by many parameters such as cyclic stability, specific capacity, specific energy and charge/discharge rate.
