摘要

本文以聚乙烯醇（PVA）包覆Ketjen black （KB）为原料合成了KB- p60阴极。KB- p60的比容量比纯KB提高了113%。此外，KB-P60在20 A g-1下实现了30,000次的超长循环寿命，并且降解最小，有效地抑制了穿梭效应。本研究为减轻锌碘电池的穿梭效应提供了一种新的途径。

Impressive improvement of zinc–iodine battery performance by doping poly(vinyl alcohol) into the cathode†

Herein, a KB-P60 cathode was synthesized from poly(vinyl alcohol) (PVA) coated Ketjen black (KB). The specific capacity of KB-P60 was increased by 113% from pure KB at 1 A g⁻¹. In addition, KB-P60 achieved an ultra-long cycle life of 30 000 cycles at 20 A g⁻¹ with minimal degradation, effectively suppressing the shuttle effect. This study provides a new approach to mitigating the shuttle effect in zinc–iodine batteries.
