ABSTRACT
Zinc ion batteries (ZIBs) encounter interface issues stemming from the water-rich electrical double layer (EDL) and unstable solid-electrolyte interphase (SEI). Herein, we propose the dynamic EDL and self-repairing hybrid SEI for practical ZIBs via incorporating the horizontally-oriented dual-site additive. The rearrangement of distribution and molecular configuration of additive constructs the robust dynamic EDL under different interface charges. And, a self-repairing organic-inorganic hybrid SEI is constructed via the electrochemical decomposition of additive. The dynamic EDL and self-repairing SEI accelerate interfacial kinetics, regulate deposition and suppress side reactions in the both stripping and plating during long-term cycles, which affords high reversibility for 500â
h at 42.7 % depth of discharge or 50â
mA â
cm-1. Remarkably, Zn//NVO full cells deliver the impressive cycling stability for 10000â
cycles with 100 % capacity retention at 3â
A â
g-1 and for over 3000â
cycles even at lean electrolyte (7.5â
µL â
mAh-1) and high loading (15.26â
mg â
cm-2). Moreover, effectiveness of this strategy is further demonstrated in the low-temperature full cell (-30 °C).
