In 2017, lithium iron phosphate (LiFePO 4) was the most extensively utilized cathode electrode material for lithium ion batteries due to its high safety, relatively low cost, high cycle performance, and flat voltage profile.
Synthesis and characterization of Li [ (Ni0. 8Co0. 1Mn0. 1) 0.8 (Ni0. 5Mn0. 5) 0.2] O2 with the microscale core− shell structure as the positive electrode material for lithium batteries J. Mater. Chem., 4 (13) (2016), pp. 4941 - 4951 J. Mater.
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.
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.
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.
Cathode material for LMROs may be improved by using doping and surface coating techniques, such as doping elements are Mg 2+, Sn 2+, Zr 4+ and Al 3+ where the coating material is Li 2 ZrO 3 [, , , , , ]. Furthermore, the LFP (lithium iron phosphate) material is employed as a cathode in lithium ion batteries.
