In many countries, anthracite has been used for a long time as a source of energy and heat. This is the purest and hardest coal available, with high levels of carbon. It also contains relatively little impurities including moisture and ash. Anthracite is cleaner burning than most other types of coke and creates less smog. Anthracite has many uses, such as in furnaces, industrial processes, and locomotives. It is difficult to find and can be costly.
New anthracite technology makes anthracite cheaper and more valuable. With a "carbonization" special process, anthracite is transformed into a cost-effective substitute for many types of other carbon. Anthracite is treated with hydrochloric acids in a process called carbonization. The carbonization of anthracite changes its structure and creates a material that is very similar to graphite. This new material is useful in a number of different ways. It can serve as an anode for an electrochemical (EDLC), or it can also be used as a material to produce graphite.
The new anthracite is suitable for high-performance lithium-ion anodes. Anodes, which allow the battery's storage and release of electrical energy, are essential components for lithium-ion. A high-capacity anode can deliver a lot of power, which is why it's used to power cars and airplanes. It is easy to make the high-performance nthracite anode and it can come in different sizes and shapes.
This research revealed that anthracite has a good storage capacity with up to 16 mA/g-1 and reversible performance after 100 cycles. The best capacity was achieved by the anthracite heat-treated at 900°C for 6 hours. This is due to the larger interspacing of graphene between layers.
The study shows that activated carbon produced commercially can be substituted with anthracite in EDLCs. The reason this is so important is that an inexpensive anode will be cheaper than a more costly high-performance one. Anthracite, a precious raw material, could be used to produce anodes that are superior in properties for next-generation lithium-ion battery. The development is exciting and will have a positive impact on consumers, producers, and the environment.
