new material can boost the performance of lithium-sulfur (Li-S) batteries.
Helmholtz-Zentrum Berlin and the Technical University of Berlin developed the material based on a porous polymer structure called a radical-cationic covalent organic framework (COF).
The study describes COF as a new “crystalline organic polymer” type with key features like high porosity, customizable structure, low density, and chemical stability.
Interestingly, the new material improved the battery performance by lasting over 1,500 cycles.
If adopted, it could enhance the capacity and stability of the next-generation lithium-sulfur batteries.
