Boosting Reversibility and Stability of Zn Anodes via Manipulation of Electrolyte Structure and Interface with Addition of Trace Organic Molecules (Adv. Energy Mater. 38/2022)

Zinc Anodes In article number 2202419, Pinhua Rao, Won Mook Choi, Jianfeng Mao, and co-workers report that a trace organic gamma butyrolactone (GBL) additive can improve the reversibility stability of Zn anode. GBL molecules rearrange ‘Zn2+-H2O-SO42−-GBL’ bonding-network aqueous electrolyte absorb on surface, reducing water activity, suppressing corrosion formation by-product, enabling uniform compact deposition.
