A Promising Carbon/g-C N Composite Negative Electrode for a Long-Life Sodium-Ion Battery.
Angew Chem Int Ed Engl
September 2019
2D graphitic carbon nitride (g-C N ) nanosheets are a promising negative electrode candidate for sodium-ion batteries (NIBs) owing to its easy scalability, low cost, chemical stability, and potentially high rate capability. However, intrinsic g-C N exhibits poor electronic conductivity, low reversible Na-storage capacity, and insufficient cyclability. DFT calculations suggest that this could be due to a large Na ion diffusion barrier in the innate g-C N nanosheet.

- Researchers are focusing on creating light-harvesting systems that can absorb a wide range of visible light for artificial photosynthesis.
- A new class of molecules called ethynyl-linked panchromatic dyads has been developed, which shows broad absorption from 300 to 636 nm.
- The study found that the way these molecules are attached affects their light absorption and performance in energy systems like dye-sensitized solar cells.
