Process optimization for producing hierarchical porous bamboo-derived carbon materials with ultrahigh specific surface area for lithium-sulfur batteries.
Benefiting from the merits of low cost, non‐flammability and high operational safety, aqueous rechargeable batteries have emerged as promising candidates for large‐scale energy storage applications. Among various metal‐ion/non‐metallic charge carriers, proton (H+) as a charge carrier possesses numerous unique properties such as a fast proton diffusion dynamics, a low molar mass and a small hydrated ion radius, which endow aqueous proton batteries (APBs) with a salient rate capability, a long‐term life span and an excellent low‐temperature electrochemical performance. In addition, redox‐active organic molecules, with the advantages of structural diversity, rich proton‐storage sites and abundant resources, are considered as attractive electrode materials for APBs. However, as far as application is concerned, the charge storage and transport mechanisms of organic electrodes in APBs is still in infancy. Therefore, finding suitable electrode materials and uncovering the H+ storage mechanisms are significant for the applications of organic materials in APBs. Herein, the latest research progresses on organic materials such as small molecules and polymers for APBs are reviewed. Furthermore, a comprehensive summary and evaluation of APBs employing organic electrodes as anode and/or cathode is provided, especially on their low‐temperature and high‐power performances, along with systematic discussions for guiding the rational design and the construction of APBs based on organic electrodes.This article is protected by copyright.
