(Qrafit və litium nədir?)

Graphite and lithium 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. Litium metalının çox aktiv kimyəvi xüsusiyyətlərinə görə, emal, litium metalın saxlanması və istifadəsi çox yüksək ekoloji tələblərə malikdir. With the development of science and technology, graphite and lithium have become the mainstream.

What are the types of graphite and lithium?

graphite and lithium 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?

Lithium Metal battery:

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:

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

6C+xLi++xe- = LixC6

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

What are the cathode materials of graphite and lithium?

Positive electrode material: There are many optional positive electrode materials. Hazırda, the common positive electrode active materials in the market are: Lithium cobalt oxide, lithium manganate, lithium nickelate, litium dəmir fosfat, nickel-cobalt-aluminum ternary, nickel-cobalt-manganese ternary

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

What are the negative electrode materials of graphite and lithium?

Negative material: graphite is mostly used. Bundan əlavə, lithium metal, lithium alloy, silicon carbon anode, oxide anode material, və s. can also be used for the anode.

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

Doldurarkən: xLi+ + xe- + 6C → LixC6

On discharge: LixC6→ xLi+ + xe- + 6C
