Lithium batteries like to use graphite anode materials

How serious are fertility problems today? People don't want to give birth,can't afford it, and can't give birth that has become the "three mountains".
The problem of childbirth is related to the people's livelihood. Whether a country can prosper or not depends on the population. I saw a set of data a few days ago. The data shows that on January 1, 1990, 2,784 babies were born in Shanghai. Ten years later, on January 1, 2000, 1,148 babies were born in Shanghai. In 2010, the number became 380. , 2020 only 156 people, the decline in the birth rate is shocking. The three most critical reasons are: I don't want to give birth, I can't afford it, I can't give birth! The decline of the global population will bring a series of economic and social problems, among which the demand for graphite will also be affected.

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.

Southern Copper Corp (SCCO.N) recently said its Peruvian mine remained closed after a six-week standoff with protesters and blamed the Peruvian government for failing to intervene in the safety of its 1,300 workers and their families.  

The company said in a statement that a recent agreement to end protests at the Cuajone mine required the company to withdraw complaints against protest leaders because railways transporting minerals and supplies remained blocked. Production has been suspended since the end of February.  

Peru's Energy Ministry said in a separate statement that it had also reached an agreement with Southern Copper to start talks to find common ground with local communities.  

"If we shut down for a year, the government will stop receiving more than 3.1 billion soles ($830 million) in taxes and royalties, and 8,000 direct and indirect jobs will be lost. This is what we want to avoid, "Southern Copper added in the statement.

Peru has faced a wave of protests from indigenous communities, who accuse mining companies of not providing enough jobs and funding to poor local residents.  

Central bank officials said last week that protests against copper mines such as MMG's Las Bambas and Southern Copper's Cuajone were dragging down the economy.  

Peru is the world's second-largest copper producer and mining is an important source of tax revenue for the country. It is estimated that the supply and prices of the graphite will be influenced by that.
