Four Major Methods for Surface Modification of Graphite Negative Electrode
Graphite negative electrode is a common negative electrode material in electrochemistry. Lithium-ion battery research is a key focus. Graphite anode material has a low charge and discharge voltage. It is safe and cheap. So, it is the main negative electrode in commercial lithium-ion batteries. However, its poor solvent compatibility and high-current performance limit use. Co-embedding solvent […]
Why is Spherical Graphite Used as Anode material?
The negative electrode material is one of the core materials of lithium-ion battery, it determines the rate performance of lithium-ion battery, it also affects the efficiency of initial charge and discharge and stability of battery cycle. Natural graphite negative electrode material is made from natural flake graphite. Through process of grinding, spheroidization, grading, purification and surface modification, natural graphite anode material […]
