Abstract Among high-capacity materials for the negative electrode of a lithium-ion battery, Sn stands out due to a high theoretical specific capacity of 994 mA h/g and the presence of a low-potential discharge plateau.

Positive electrode materials have diversified as the increase in the role of lithium batteries as power sources from mobile electronics to transportation applications.
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
length and height of the battery are neglected. The example uses the following domains: • Negative porous electrode: 50 μm † Separator: 50 μm † Positive porous electrode: 50 μm Two active intercalating materials are considered in the positive electrode and the negative electrode consists of a single intercalating material. The model includes the following processes (Ref. 1
Lithium metal was used as a negative electrode in LiClO 4, LiBF 4, LiBr, LiI, or LiAlCl 4 dissolved in organic solvents. Positive-electrode materials were found by trial-and-error investigations of organic and inorganic materials in the 1960s.
The positive electrode is activated carbon and the negative electrode is Li [Li 1/3 Ti 5/3 ]O 4. The idea has merit although the advantage of lithium-ion battery concept is limited because the concentration of lithium salt in electrolyte varies during charge and discharge.
Hence, the current scenario of electrode materials of Li-ion batteries can be highly promising in enhancing the battery performance making it more efficient than before. This can reduce the dependence on fossil fuels such as for example, coal for electricity production. 1. Introduction
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.
The positive electrodes that are most common in Li-ion batteries for grid energy storage are the olivine LFP and the layered oxide, LiNixMnyCo1-x-yO2 (NMC). Their different structures and properties make them suitable for different applications .
The anode and cathode electrodes play a crucial role in temporarily binding and releasing lithium ions, and their chemical characteristics and compositions significantly impact the properties of a lithium-ion cell, including energy density and capacity, among others.
