Redox‐Bipolar Polyimide Two‐Dimensional Covalent Organic Framework Cathodes for Durable Aluminium Batteries

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(30)

Published: May 19, 2023

Emerging rechargeable aluminium batteries (RABs) offer a sustainable option for next-generation energy storage technologies with low cost and exemplary safety. However, the development of RABs is restricted by limited availability high-performance cathode materials. Herein, we report two polyimide two-dimensional covalent organic frameworks (2D-COFs) cathodes redox-bipolar capability in RAB. The optimal 2D-COF electrode achieves high specific capacity 132 mAh g-1 . Notably, presents long-term cycling stability (with negligible ≈0.0007 % decay per cycle), outperforming early reported RAB cathodes. 2D-COFs integrate n-type imide p-type triazine active centres into periodic porous polymer skeleton. With multiple characterizations, elucidate unique Faradaic reaction electrode, which involves AlCl2+ AlCl4- dual-ions as charge carriers. This work paves avenue toward novel RABs.

Aqueous zinc ions batteries (AZIBs) using non-organic electrolytes have garnered sustained interest as a future energy storage technology, primarily due to their low cost, environmental friendliness, and intrinsic safety. However, ion suffer from series of serious challenges, including hydrogen evolution reaction (HER) at the anode, surface passivation, dendrite formation, well limited operating voltage comparatively density. These factors are all influenced by concentration H+ in electrolyte (i.e., pH), its fluctuations during cycle process. To date, there remains lack systematic evaluation correlation between pH value challenges faced AZIBs, or focused review how influences electrochemical performance AZIBs strategies that can be used improve cell efficiency. In this we emphasize strong detail research progress made recent years relating additives, separator modification, interfacial protective layers, battery system design, with particular focus on regulatory mechanisms associated control. On basis, propose important focuses suggestions for onward development AZIBs.
