Combined with previous examples of high energy density (capacitance/storage), the choice of anthracite is a promising one. Anthracite is the superior choice of coal and is the ideal material as a carbon source, with applications from the foundry all the way to the desalination plant.
Anthracite has long been used as an electrode material in various electrochemical cells for the purpose of metal treatment, but contemporary research shows potential promising use cases as electrodes in novel batteries.
Perhaps counterintuitively, anthracite has certain refractory uses - despite the fact that at high temperatures it has a tendency to combust. Smelter linings are one of several uses in the modern foundry, where anthracite is used as part of the refractory lining of the bases (hearths) of blast furnaces.
Charged with the removal of organic residues and as a general filter, anthracite’s coarse nature makes it an ideal choice at removing suspended solids, salts and other residues. Solvent extraction electrowinning is used extensively for the production of high grade copper, cobalt, zinc and nickel from their ores (7,8).
Therefore, the excellent electrochemical performance verifies a potential feasibility for the production of synthetic graphite materials from anthracite coal in a large scale for high-performance anodes in lithium-ion batteries. This article is cited by 23 publications.
Anthracite is able to improve upon already successful anode/battery systems. Research has shown that the addition of anthracite to a red phosphorus anode increases its specific capacity to 810 mA h g −1 from 420 mA h g −1 for the pure phosphorus (18).

Anthracite coal holds great promise as a prospective anode material for sodium ion batteries. However, traditional preparation methods suffer from prolonged calcination time and significant energy consumption, impeding …
In this work, we propose an effective strategy to prepare low-cost hard carbon (HC) anode materials by using pre-oxidation anthracite as a precursor. The carboxyl groups (C=O and -COOH) were successfully introduced into the hard carbon material, and the content of carboxyl groups (C=O) increased.
These excellent properties meet the requirements of practical applications and lay the foundation for the industrial production of low-cost, high-safety sodium-ion batteries for large-scale energy storage.

Anthracite is also known for its high energy level, so it is often used as a heat source. However, a new application is emerging in the form of converting it into an anode material for SIB batteries. Although it is the rarest type of coal, its existing reserves are still sufficient and cost-effective for use as sustainable anode ...
Saltwater batteries have a lower energy density than lithium-ion batteries, meaning they store less energy in the same amount of space. This is problematic because a lower energy density means a larger physical battery, and larger batteries use more materials and cost more to produce. As lithium-ion battery prices continue to fall, the cost challenge for …
Synthetic graphite is an ideal anode material, which could replace the natural graphite for Li-ion batteries. However, high-temperature graphitization makes the process costly and energy-intensive, which impedes its larger-scale production and commercial applications.

Due to the increasingly serious problems of the greenhouse effect and environmental pollution caused by the continuous consumption of traditional fossil energy, renewable and clean energy (such as solar energy and wind energy) is facing new opportunities and challenges. However, renewable energy has intermittent and regional defects, and …
SIBs have the potential to outperform lithium-ion batteries (LIBs) in terms of high and low-temperature resistance, safety, and electrolyte conductivity [1, 2], which makes them a new generation of potentially efficient electrochemical energy storage devices that can be substituted for LIBs, and especially well suited for the solution of large-scale energy storage …
In addition, growing economies in the Far East, South America and India are driving up demand for anthracite.
