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. When the lithium-ion battery is charged, the lithium atoms in the positive electrode are ionized into lithium ions and electrons, and the lithium ions move to the
Lithium–carbons are currently used as the negative electrode reactant in the very common small rechargeable lithium batteries used in consumer electronic devices.

TiO2 is a naturally abundant material with versatile polymorphs, which has been investigated in various fields, such as photocatalysis, electrochromic devices, lithium‐ion batteries, amongst others.

Since the 1950s, lithium has been studied for batteries since the 1950s because of its high energy density. In the earliest days, lithium metal was directly used as the anode of the battery, and materials such as manganese dioxide (MnO 2) and iron disulphide (FeS 2) were used as the cathode in this battery.However, lithium precipitates on the anode surface to form

The active materials in the electrodes of commercial Li-ion batteries are usually graphitized carbons in the negative electrode and LiCoO 2 in the positive electrode.

At similar rates, the hysteresis of conversion electrode materials ranges from several hundred mV to 2 V [75], which is fairly similar to that of a Li-O 2 battery [76] but much larger than that of a Li-S battery (200–300 mV) [76] or a traditional intercalation electrode material (several tens mV) [77]. It results in a high level of round-trip energy inefficiency (less than 80%
We have developed a method which is adaptable and straightforward for the production of a negative electrode material based on Si/carbon nanotube (Si/CNTs) composite for Li-ion batteries. Comparatively inexpensive silica and magnesium powder were used in typical hydrothermal method along with carbon nanotubes for the production of silicon nanoparticles.

CC-BY 4.0 . The pursuit of new and better battery materials has given rise to numerous studies of the possibilities to use two-dimensional negative electrode materials, such as MXenes, in lithium-ion batteries.
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.
As discussed below, this leads to significant problems. Negative electrodes currently employed on the negative side of lithium cells involving a solid solution of lithium in one of the forms of carbon. Lithium cells that operate at temperatures above the melting point of lithium must necessarily use alloys instead of elemental lithium.
This type of cell typically uses either Li–Si or Li–Al alloys in the negative electrode. The first use of lithium alloys as negative electrodes in commercial batteries to operate at ambient temperatures was the employment of Wood’s metal alloys in lithium-conducting button type cells by Matsushita in Japan.
