Stretchable Zn‐Ion Hybrid Battery with Reconfigurable V₂CT<i>_x</i> and Ti₃C₂T<i>_x</i> MXene Electrodes as a Magnetically Actuated Soft Robot (Adv. Energy Mater. 45/2021)

摘要

Zn-Ion Hybrid Batteries In article number 2101862, Yusheng Zhao, Po-Yen Chen and co-workers report stretchable Zn-Ion hybrid batteries composed of V2CTx MXene cathodes and zinc-decorated Ti3C2Tx MXene anodes with crumple-like microtextures, enabling unique folding/unfolding behaviors to attenuate in-plane stress. The stretchable Zn-ion battery is rechargeable and features large deformability, ultrathin device configuration, low areal weight, and ultralow self-discharge rates. The stretchable battery can be further transformed into a magnetically actuated soft robot with remote control, capable of crawling back and forth for charging/discharging tasks.
