Lithium batteries like to use graphite anode materials

In terms of international pricing benchmarks, according to the CP data released by Saudi Aramco, the propane contract price (CP) in March was $895 / ton, up $120 / ton from the previous month, up 15.48% from the previous month and up 43.20% from the same period last year. Butane contract price (CP) in March was 920 US dollars/ton, up 145 US dollars/ton compared with last month, up 18.71% month-on-month, up 54.62% compared with the same period last year; In March, CP in Saudi Arabia rose sharply, giving a strong boost to the international and domestic LPG market. Benchmark LPG prices are higher than a year ago as the economy continues to recover and demand for crude oil continues to repair. According to this trend, the market price of graphite will also be affected to a certain extent.

Lithium-ion battery refers to a secondary battery system in which two different lithium intercalation compounds that can reversibly intercalate and deintercalation lithium ions are used as the battery's positive electrode and negative electrode, respectively. During charging, lithium ions are deintercalated from the positive electrode through the electrolyte and separator and embedded in the negative electrode; on the contrary, lithium ions are deintercalated from the negative electrode through discharge of the electrolyte the separator and embedded in the positive electrode. The negative electrode of the lithium-ion battery is made of harmful electrode active material, binder, and additives mixed to make a paste glue, which is evenly spread on both sides of the copper foil, dried, and rolled.

Advantages of graphite as anode material

Graphite is an allotrope of carbon, and the two are closely related. Graphite is the most stable form of carbon. (Diamond is a metastable allotrope of carbon. Although its hardness is much higher than graphite, it is the hardest substance in nature, but its stability is lower than that of graphite.)

The word "graphite" comes from the Greek word "graphein," which is resistant to high temperature and corrosion, has good electrical conductivity, thermal conductivity, and stable chemical properties, and is lighter than aluminum. In addition to being used as anode material for lithium-ion batteries, high-quality graphite can also be used in different fields such as fuel cells, solar cells, semiconductors, light-emitting diodes, and nuclear reactors.

In general, graphite has the advantages of high electronic conductivity, the small volume change of layered structure before and after lithium intercalation, high lithium intercalation capacity, and low lithium intercalation potential, and has become the mainstream commercial lithium-ion battery negative electrode material.

How to get graphite?

There are two ways to obtain graphite: one is natural ore, and the other is the synthesis of coal tar. The graphite materials used in lithium-ion batteries are generally prepared by blending 55% synthetic graphite and 45% low-purity natural graphite.

Manufacturers once favored synthetic graphite because the uniformity and purity of synthetic graphite were better than natural graphite. Now it is not the same. The application of modern chemical purification methods makes it possible to obtain 99.9% pure natural graphite after heat treatment. In contrast, synthetic graphite is 99% pure, making the former more popular.

Compared with synthetic graphite, purified natural flake graphite has higher crystallinity and exhibits better electrical and thermal conductivity. In addition, natural graphite is expected to reduce the production cost of lithium-ion batteries while achieving equal or better battery performance.

Recently, the Turkish government announced that the Turkish President has signed a presidential decree to provide incentives for its Black Sea gas field development projects, including tax exemptions and other preferential measures.  

With a fixed investment of 145.1 billion Turkish lira ($10 billion), the project will employ 1,018 people and produce 14 billion standard cubic meters of gas per year, the decree reads. The incentives involved include tariff and VAT exemptions, as well as a range of tax cuts.

In June 2021, Turkish drill ships discovered 135 billion cubic meters of natural gas in the Sakaria field in the Black Sea, bringing Turkey's total gas discoveries in the region to 540 billion cubic meters.  

Turkey imports almost all of its annual gas consumption of about 50 billion cubic meters.  

Except for natural gas, the supply and prices of many other graphite will continue to be influenced by international situations.
