Lead-acid battery (LAB) has been in widespread use for many years due to its mature technology, abound raw materials, low cost, high safety, and high efficiency of recycling. However, the irreversible sulfation in the negative electrode becomes one of the key issues for its further development and application. Lead-carbon battery (LCB) is evolved from LAB by …
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.
Graphitized carbons have played a key role in the successful commercialization of Li-ion batteries. The physicochemical properties of carbon cover a wide range; therefore, identifying the optimum active electrode material can be time consuming.
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.
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.
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.
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 ).

A major leap forward came in 1993 (although not a change in graphite materials). The mixture of ethyl carbonate and dimethyl carbonate was used as electrolyte, and it formed a lithium-ion battery with graphite material. After that, graphite material becomes the mainstream of LIB negative electrode [4]. Since 2000, people have made continuous ...
In the case of carbon-based lithium ion batteries, lithiated carbon is a powerful reducing agent (negative electrode) whereas a metal oxide constitutes the oxydant positive electrode. As the battery is assembled with profit in the discharged state where the active materials present low reactivity to the environment, it is the positive material that has to be in a …
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 ...

Since the cracking of carbon materials when used as negative electrodes in lithium batteries is very small, several allotropes of carbon can be used, including amorphous carbon, hard carbon, graphite, carbon nanofibers, multi-walled carbon nanotubes (MWNT), and graphene [26]. Carbon-based materials are characterized by efficient stress absorption during electrochemical …

Fig. 1 Schematic of a discharging lithium-ion battery with a lithiated-graphite negative electrode (anode) and an iron–phosphate positive electrode (cathode). Since lithium is more weakly bonded in the negative than in the positive electrode, lithium ions flow from the negative to the positive electrode, via the electrolyte (most commonly LiPF 6 in an organic, …

For the negative electrode, the first commercially successful option that replaced lithium–carbon-based materials is also difficult to change.
