Zinc-ion batteries (ZIBs) represent a promising energy-storage device, which has remarkable merits in terms of cost-effectiveness, high safety, and environmental sustainability. Transition metal chalcogenides are emerging cathode materials for ZIBs due to their theoretical capacity large interlayer spacing. Nevertheless, application faces critical challenges sluggish reaction kinetics huge volume variation. Herein, the anion defect engineering strategy one-step situ anchoring vanadium sulfoselenide on V2CTx template (VSSe/V2CTx) in-plane heterostructure with built-in vacancy is proposed by robust interfacial C─Se─V bonds overcome these challenges. The incorporation Se atom into VS2 not only changes V electronic structure enhances intrinsic electrical conductivity VSSe/V2CTx, but also creates more active sites accelerates as confirmed calculations experimental results. Thus, VSSe/V2CTx delivers 114.3 mAh g-1 at 5 A over 15 000 cycles under cryogenic conditions quasi-solid state (QSSZIBs). Furthermore, two QSSZIBs successfully integrated hydrogel strain sensor enabling reliable human motion physiological signal detection, highlighting promise self-powered wearable healthcare monitoring management systems.
