Graphite and related carbonaceous materials can reversibly intercalate metal atoms to store electrochemical energy in batteries. 29, 64, 99-101 Graphite, the main negative electrode material for LIBs, naturally is considered to be the most suitable negative-electrode material for SIBs and PIBs, but it is significantly different in graphite negative-electrode materials between SIBs and
Rapid industrial growth and the increasing demand for raw materials require accelerated mineral exploration and mining to meet production needs [1,2,3,4,5,6,7].Among some valuable minerals, lithium, one of important elements with economic value, has the lightest metal density (0.53 g/cm 3) and the most negative redox-potential (−3.04 V), which is widely used in

In order to improve the energy/power density and cyclic life of a lithium ion batery, its electrode materials and electrolyte must be properly chosen. Cathode materials store energy through intercalation or con-version reactions, while the energy storage mechanism in anode materials are intercalation, conversion reactions or alloying/dealloying.

Lithium-ion Battery. A lithium-ion battery, also known as the Li-ion battery, is a type of secondary (rechargeable) battery composed of cells in which lithium ions move from the anode through an electrolyte to the cathode during discharge and back when charging.. The cathode is made of a composite material (an intercalated lithium compound) and defines the name of the Li-ion
The development of lithium-ion batteries (LIBs) has progressed from liquid to gel and further to solid-state electrolytes. Various parameters, such as ion conductivity, viscosity, dielectric constant, and ion transfer number, are desirable regardless of the battery type. The ionic conductivity of the electrolyte should be above 10−3 S cm−1. Organic solvents combined with

Among the lithium-ion battery materials, the negative electrode material is an important part, which can have a great influence on the performance of the overall lithium-ion battery.

NiCo 2 O 4 has been successfully used as the negative electrode of a 3 V lithium-ion battery. 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
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.
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.
A great volume of research in Li-ion batteries has thus far been in electrode materials. Electrodes with higher rate capability, higher charge capacity, and (for cathodes) sufficiently high voltage can improve the energy and power densities of Li batteries and make them smaller and cheaper.
