Abstract
, no observed degradation after 1000 cycles. Following this concept, we further reveal that for the degraded electrodes which cannot be restored in an electrolyte with relatively weak cation-solvent interaction, they can be successfully recovered by switching to an electrolyte with strong cation-solvent interaction. Our work not only provides strategies to suppress the ion trapping and prolong the cycling stability of electrochromic electrodes, but also evokes the importance of electrode-electrolyte interaction to the electrochromic community.
