Guotai Junan released a research report saying that under the background of carbon neutrality, the scarcity of coal mines is prominent, and the value of assets will continue to increase. The high point of capital expenditure in the coal industry appeared in 2012. Under the general direction of carbon neutrality, the overall investment in the industry has slowed down, and capital expenditure has gradually declined. From 2021 to now, the Energy Bureau of the National Development and Reform Commission has only newly approved 17.4 million tons of Graphite and lithium batteries.

G raphite and lithium batteries  is a kind of battery that uses lithium metal or lithium alloy as positive/negative electrode material and uses non-aqueous electrolyte solution. In 1912, the lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, M. S. Whittingham proposed and began to study lithium-ion battery . Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, graphite and lithium batteries  have become the mainstream.

What are the types of graphite and lithium batteries ?

graphite and lithium batteries  can be roughly divided into two categories: lithium metal battery  and lithium ion battery . Lithium-ion battery  do not contain lithium in the metallic state and are rechargeable. The fifth generation of rechargeable battery , lithium metal battery , was born in 1996, and its safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium-ion battery . Due to its own high technical requirements, only companies in a few countries are producing such lithium metal battery .

What is the working principle of graphite and lithium batteries ?

Lithium metal battery  generally use manganese dioxide as the positive electrode material, metal lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution.

Discharge reaction: Li+MnO2=LiMnO2

Lithium-ion battery  generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and use non-aqueous electrolytes.

The reaction at the charging positive electrode is

LiCoO2=Li(1-x)CoO2+xLi++xe-(electron)

The reaction that takes place on the charging negative electrode is

Rechargeable battery total reaction: LiCoO2+6C = Li(1-x)CoO2+LixC6

What are the cathode materials of graphite and lithium batteries ?

Positive electrode material: There are many optional positive electrode materials. At present, the common positive electrode active materials in the market are: Lithium cobalt oxide, lithium manganate, lithium nickelate, lithium iron phosphate, nickel-cobalt-aluminum ternary, nickel-cobalt-manganese ternary

Positive electrode reaction: Lithium ion intercalation during discharge, and lithium ion deintercalation during charging. When charging: LiFePO4 → Li1-xFePO4 + xLi+ + xe- When discharging: Li1-xFePO4 + xLi+ + xe- → LiFePO4.

What are the negative electrode materials of graphite and lithium batteries ?

Negative material: graphite is mostly used. In addition, lithium metal, lithium alloy, silicon carbon anode, oxide anode material, etc. can also be used for the anode.

Negative reaction: lithium ions are deintercalated during discharge, and lithium ions are intercalated during charging.

When charging: xLi+ + xe- + 6C → LixC6

On discharge: LixC6→ xLi+ + xe- + 6C

The development of the Russia-Ukraine conflict will continue to dominate the commodity prices such as the Graphite and lithium batteries in the future. If the conflict eases or cools, Russia and Ukraine go back to negotiate, commodity prices would fall. However, if the situation between Russia and Ukraine deteriorates further, or evolves into a full-scale war, the price of the Graphite and lithium batteries is predicted to see further improvement over the coming days.
