What are the characteristics of lithium -ion battery negative materials? -Lithium - Ion Battery Equipment
The negative electrode of a lithium -ion battery is coated with a negative active material carbon material or non -carbon material, adhesive and additive confusion, which is properly applied to the sides of the copper foil on both sides of the copper foil, which is dry and rolled. Can lithium -ion batteries be made? The essence is whether it can prepare the negative electrode material that can be reversed/embedded with lithium ions.(Lithium - Ion Battery Equipment)
What are the types of negative materials?
▼ Carbon negative material
In actual applications, the carbon negative material of lithium -ion batteries is basically these carbon quality materials: artificial graphite, natural graphite, petroleum scorch, and carbon fiber.
▼ tinyl negative material
The general environment of tin -based negative materials can be divided into two types, one is the oxide of the tin, and the other is tincer composite oxides. The oxides of the tin generally refer to the oxides of metal tin in various prices.
▼ Lithium transition metal nitride negative materials
This kind of negative material is still in the research stage, and it has not yet been presented as a trade lithium -ion battery product with its negative material.
▼ Metal -class negative material material
There are many types of negative materials for lithium -ion battery alloy alloys. There are still many types of alloys that are included in the vast examples of alloy, silicon -based alloy, aluminum -based alloy, etc. Limited production is still under development.
▼ Nano -level negative material material
The nano -level negative material can add smaller other materials to the previous traditional negative materials, thereby greatly increasing the charge and discharge of lithium -ion batteries and the number of charging and discharge.
Principles of selecting negative electrode materials
High -energy ratio: The electrode potential of the lithium electrode is lower; good reversibility: good reversibility of charging and discharge; good compatibility: good compatibility with electrolytes and adhesives; smaller appearance: best: best It is less than 10m2/g, and the real density is high: it should be greater than 2.0g/cm3; the size of the non -degeneration is good: the size and machine constant function in the process of lithium inlaid.
