A Hofmeister effect induced hydrogel electrolyte–electrode interfacial adhesion enhancement strategy for energy-efficient and mechanically robust redoxcapacitors

Relying on Hofmeister effect, the interface adhesion of the hydrogel electrolyte on both the anode and cathode is tremendously enhanced, thus intensified energy efficiency and mechanical toughness of the fabricated flexible Zn-ion redoxcapacitor.
