A rechargeable aqueous manganese-ion battery based on intercalation chemistry

Nature Communications, Год журнала: 2021, Номер 12(1)

Опубликована: Ноя. 30, 2021

Abstract Aqueous rechargeable metal batteries are intrinsically safe due to the utilization of low-cost and non-flammable water-based electrolyte solutions. However, discharge voltages these electrochemical energy storage systems often limited, thus, resulting in unsatisfactory density. Therefore, it is paramount importance investigate alternative aqueous battery improve voltage. Herein, we report reversible manganese-ion intercalation chemistry an solution, where inorganic organic compounds act as positive electrode active materials for Mn 2+ when coupled with a Mn/carbon composite negative electrode. In one case, layered 0.18 V 2 O 5 ·nH cathode demonstrates fast insertion/extraction large lattice spacing, enabling adequate power performances stable cycling behavior. other tetrachloro-1,4-benzoquinone molecules undergo enolization during charge/discharge processes, contributing achieving cell plateau at about 1.37 V. Interestingly, low redox potential Mn/Mn couple vs. standard hydrogen (i.e., −1.19 V) enables production manganese cells operational higher than their zinc counterparts.

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.
