Ion pre-intercalation regulating the tunnel structure of electrode materials accelerates Zn2+ insertion kinetics to realize a high energy storage contribution of Zn-ion batteries. However, electrostatic interaction induced by the pre-intercalated cation and multivalent Zn2+ ions hinders the insertio...
