High‐Performance Wide‐pH Zn‐Based Batteries via Electrode Interface Regulation with Valine Additive

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 34(13)

Published: Dec. 15, 2023

Abstract Aqueous zinc (Zn) based batteries show great promise as energy storage devices, cost‐effectiveness, and intrinsic safety. However, the development of Zn‐based faces significant challenges, primarily stemming from poor electrochemical reversibility caused by dendrite growth, hydrogen generation, byproduct formation on Zn anode. In this study, valine (Val) is investigated an electrolyte additive to finely tune interface microenvironment, resulting in enhanced stability anode across a wide pH range, marking first time such approach has been explored. Val ions preferably adsorb onto active sites surface, enabling efficient isolation water SO 4 2− desolvated shell layer thus effectively inhibiting growth. The Zn||Zn symmetric cells are demonstrated with additives present remarkable cycling performance 5400 h. Furthermore, Zn||MnO 2 full exhibit stable operation for 5000 cycles at 3 A g −1 . Notably, also functions rechargeable alkaline cells, Zn||Ni 0.8 Co 0.1 Mn O operate durably temperature range.

Regeneration of spent lithium manganate into cation‐doped and oxygen‐deficient MnO₂ cathodes toward ultralong lifespan and wide‐temperature‐tolerant aqueous Zn‐ion batteries

Battery energy, Journal Year: 2023, Volume and Issue: 2(4)

Published: May 22, 2023

Abstract Manganese‐based compounds have been regarded as the most promising cathode materials for rechargeable aqueous zinc‐ion batteries (AZIBs) due to their high theoretical capacity. Unfortunately, Zn–manganese dioxide (MnO 2 ) poor cycling stability and are unstable across a wide temperature range, severely limiting commercial application. Cationic preinsertion defect engineering might increase active sites electron delocalization, which render mobility of MnO when operated range. In present work, first time, we successfully introduced lithium ions ammonium into manganese (LNMO d @CC) by an electrodeposition combined with low‐temperature calcination route using spent manganate raw material. The obtained LNMO @CC exhibits reversible capacity (300 mAh g −1 at 1 A outstanding long lifespan over 9000 cycles 5.0 152 , is significant both high‐value recycling high‐performance modification cathodes.
