AI Technical Summary
Existing technologies make it difficult to stably disperse carbon materials in aprotic polar solvents, leading to reduced conductivity and affecting the performance of electrochemical components. In particular, the use of dispersants in electrochemical components such as lithium-ion batteries may hinder conductivity and increase complexity.
By adding specific substituents, such as metal ions, organic amines, or ammonium substituents, to the surface of carbon materials, surface-modified carbon materials are formed. These substituents are used to achieve the self-dispersion of carbon materials in aprotic polar solvents, avoiding the use of dispersants.
Stable dispersion of carbon materials in aprotic polar solvents was achieved, which improved the conductivity and dispersibility of electrochemical components, reduced the negative impact of dispersant use on battery performance, and enhanced the overall performance of electrochemical components.
