📌 Key Highlights & Quick Takeaways:
- Researchers at the Chinese Academy of Sciences have developed a new aluminum-based catalyst that could help improve the lifespan and perform.
- According to the researchers, a major problem with these batteries is the migration of sodium polysulfides away from the cathode, which shor.
- The research team changed the atomic structure of aluminum by replacing an oxygen atom with nitrogen, creating a new structure called Al–O3N.
Researchers at the Chinese Academy of Sciences have developed a new aluminum-based catalyst that could help improve the lifespan and performance of sodium-sulfur batteries.
According to the researchers, a major problem with these batteries is the migration of sodium polysulfides away from the cathode, which shortens battery life.
The research team changed the atomic structure of aluminum by replacing an oxygen atom with nitrogen, creating a new structure called Al–O3N. This change strengthened the interaction between aluminum and sulfur and improved the speed and stability of the chemical reactions inside the battery.
In laboratory experiments, the battery maintained a capacity of 1196 milliampere-hours per gram after 100 charge-discharge cycles.
