Graphitization Degree of Carbon Materials

 Carbon materials are currently the ideal anode materials for lithium-ion batteries. The type of carbon material determines the lithium intercalation potential and the reversibility performance of the operating voltage of lithium-ion batteries. Gravimetric capacity is an important indicator for measuring carbon materials, but testing the gravimetric capacity is usually done through battery testing; this is very time-consuming, and the stability of the test values is relatively low.

The degree of graphitization refers to the proportion of graphite crystals in composite materials containing graphite crystals and various transitional carbon phases. Theoretically, the gravimetric capacity of carbon materials can be predicted according to the degree of graphitization. XRD can confirm the presence of graphite structure, evaluate the degree of graphitization and crystallization, and thus calculate the gravimetric capacity of carbon materials.

Lithium Battery Materials

Examining the structure and structural changes of ternary materials is useful for better understanding the performance of ternary materials. XRD is a device specifically used to analyze the crystal structure of materials. It can obtain the unit cell parameters and ion mixing information of ternary materials through refinement and is widely used in ternary material preparation technology, material doping modification, as well as in determining the in-situ high-temperature thermal properties of ternary materials. In-situ charge and discharge XRD experiments can directly investigate the structural changes and phase transitions of positive and negative electrode materials during the charge and discharge process of button-type lithium-ion battery materials. In addition, XRD technology can also be used to perform thermal failure analysis of lithium-ion batteries, for example, by conducting XRD analysis of combustion residues to initially determine the cause of the failure.
