The negative electrode material is the main body of lithium ion battery to store lithium, so that lithium ions are inserted and extracted during the charging and discharging process.
Simultaneously, the term “lithium-ion” was used to describe the batteries using a carbon-based material as the anode that inserts lithium at a low voltage during the charge of the cell, and Li 1−x CoO 2 as cathode material. Larger capacities and cell voltages than in the first generation were obtained ( Fig. 1 ).
For example, silicon-based materials, alloy materials, tin-gold materials, and the like. The negative electrode of lithium ion battery is made of negative electrode active material carbon material or non-carbon material, binder and additive to make paste glue, which is evenly spread on both sides of copper foil, dried and rolled.
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.
However, the use of lithium metal as anode material in rechargeable batteries was finally rejected due to safety reasons. What caused the fall in the application of rechargeable lithium-anode batteries is also well known and analogous to the origin of the lack of zinc anode rechargeable batteries.
Two lines of research can be distinguished: (i) improvement of LiCoO 2 and carbon-based materials, and (ii) replacement of the electrode materials by others with different composition and structure. Concerning the positive electrode, the replacement of lithium cobaltate has been shown to be a difficult task.
