To enhance the performance and stability of zinc-ion batteries through molecular functionalization of separators.
Developed nanocellulose separators with dynamic Zn2+-coordinating nitrogen sites.
Evaluated battery performance over 4000 cycles at ∼10 C.
The pouch cell retains 85.8% capacity after 4000 cycles.
Enhanced stability is achieved through electrostatic potential gradients in separators.
Abstract
cathode, the full pouch cell retains 85.8% of its capacity after 4000 cycles at ∼10 C. This work highlights that molecular functionalization of separators enables next-generation aqueous Zn batteries.
