There has been a large amount of work on the understanding and development of graphites and related carbon-containing materials for use as negative electrode materials in lithium batteries since that time. Lithium–carbon materials are, in principle, no different from other lithium-containing metallic alloys.
It should be noted that the potential applicability of this anode material in commercial lithium-ion batteries requires a careful selection of the cathode material with sufficiently high voltage, e.g. by using 5 V cathodes LiNi 0.5 Mn 1.5 O 4 as positive electrode.
Therefore, it is reasonable to speculate that in the lithium-deficient scenario, the rapid consumption of active lithium metal in the negative electrode leads to the delithiation of Li 2 O to supplement lithium ions and maintain battery cycling 66.
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.
Silicon current density high at low state-of-charge due to low mass fraction. Silicon peak reaction current density reduced by increasing the volume fraction. Silicon is a promising negative electrode material with a high specific capacity, which is desirable for commercial lithium-ion batteries.
