Amphoteric Polymer Strategy with Buffer‐Adsorption Mechanism for Long‐Life Aqueous Zinc Ion Batteries
Zhejiang University · State Key Laboratory of Chemical Engineering
Abstract
Abstract Water‐based secondary batteries with multivalent metals anode provide a promising option for energy storage with low cost and high security. However, the electrochemical performance of aqueous Zinc ion batteries (AZIBs) is mainly restricted by problems such as poor reversibility and hydrogen evolution. Herein, an “amphoteric polymer strategy” with buffer‐adsorption mechanism for AZIBs is proposed by introducing poly‐L‐Glutamic Acid (PGA) into the electrolyte. Amphoteric polymer enriched functional carboxyl and amino groups confer high compatibility of the Zn metal anodes as well as the relative stability of the bulk electrolyte pH simultaneously. Partial PGA molecules distributed in bulk electrolyte…
