Application Case: Sintering of Lithium Battery Ternary Materials in a 1700℃ Vacuum Atmosphere Furnace

Background

Ternary lithium battery materials (such as nickel cobalt manganese oxide, NCM) are widely used in electric vehicles and energy storage devices due to their excellent electrochemical properties and high energy density. Sintering in a 1700℃ vacuum atmosphere furnace can improve the structural stability of the material and the battery performance.

 Equipment Overview:

Using a 1700°C vacuum atmosphere furnace, it has the following features: 

High temperature capability: Stable operation up to 17001700℃, suitable for high temperature sintering needs. 

Vacuum environment: Sintering in a low oxygen environment to prevent material oxidation. 

Atmosphere control: The atmosphere composition can be precisely controlled to improve the purity and performance of the material. 

Material preparation:

Raw materials: High-purity nickel, cobalt, and manganese precursor compounds (such as nitrates and hydroxides). 

Additives: A lithium source (such as lithium carbonate) can be used to adjust the lithium content. 

Sintering process:

Powder mixing: Mix the nickel, cobalt, and manganese precursors with the lithium source in proportion to ensure uniformity.

Molding: Prepare the green body of the desired shape by pressing or dry molding technology.

Drying: Dry at an appropriate temperature to remove moisture and solvent.

Vacuum sintering:

Put the green body into a vacuum atmosphere furnace and evacuate to the required pressure.

Gradually increase the temperature to 1700°C and maintain it for a certain time to promote reaction and sintering.

Cool to room temperature and maintain a vacuum environment.

Results and analysis:

Phase composition: X-ray diffraction (XRD) analysis confirms the formation of the target phase, such as LiNi₁/₃Co₁/₃Mn₁/₃O₂.

Density test: The density of the sintered material is significantly improved, indicating a good sintering effect.

Electrochemical performance: Cyclic voltammetry (CV) and charge and discharge tests were performed, showing excellent capacity retention and cycle stability.

Application:

Sintered lithium battery ternary materials are widely used in: 

Electric vehicle batteries: Improve endurance and charging speed.

Energy storage system: Provide efficient solutions in renewable energy storage and smart grids.

Conclusion:

The process of sintering lithium battery ternary materials in a 1700°C vacuum atmosphere furnace significantly improves the structural stability and electrochemical performance of the materials, providing a reliable material basis for the lithium battery industry. This technology has broad application prospects in the future development of lithium batteries.
