💡 Novelty & Significance:
The novelty is using a dimeric 4-tert-butylcalix[8]arene molecular capsule to encapsulate metal acetylacetonate redox species, boosting solubility and stability. This significantly advances non-aqueous redox flow batteries, achieving 90.41% capacity retention after 1000 cycles versus 52.2% after 400 cycles without capsules, offering a promising strategy for long-lifetime, high-performance grid-scale energy storage.
