To sustainably satisfy the growing demand for energy, organic carbonyl compounds (OCCs) are being widely studied as electrode active materials for batteries owing to their high capacity, flexible structure, low cost, environmental friendliness, renewability, and universal applicability. However, their high solubility in electrolytes, limited active sites, and low conductivity are obstacles in increasing their usage. Here, the nucleophilic addition reaction of aromatic carbonyl compounds (ACCs) is first used to explain the electrochemical behavior of carbonyl compounds during charge–discharge, and the relationship of the molecular structure and electrochemical properties of ACCs are discussed. Strategies for molecular structure modifications to improve the performance of ACCs, i.e., the capacity density, cycle life, rate performance, and voltage of the discharge platform, are also elaborated. ACCs, as electrode active materials in aqueous solutions, will become a future research hotspot. ACCs will inevitably become sustainable green materials for batteries with high capacity density and high power density.

“…Organic electrodes materials are also feasible for aqueous AZBs. Very recently, Chen and co‐workers reported the application of quinone electrodes in aqueous zinc battery. The results indicated that the quinone compounds with carbonyls in ortho ‐position (1,2‐naphthoquinone (1,2‐NQ) and 9,10‐phenanthrenequinone (9,10‐PQ)) generally show lower capacity and larger polarization than those with carbonyls in para ‐position (1,4‐naphthoquinone (1,4‐NQ), 9,10‐anthraquinone (9,10‐AQ), and calix[4]quinone (C4Q)) due to the larger steric hindrance.…”

Given the low cost, ease of fabrication, high safety, and environmental‐friendly characteristics, aqueous rechargeable batteries using mild aqueous solutions as electrolytes (pH is close to 7) and a monovalent/multivalent metal ion as charge carrier, are attracting extensive attention for energy storage. However, accompanied by advantages of mild aqueous electrolyte mentioned above, there are some challenges that stand in the way of the development of these aqueous rechargeable batteries, such as the narrow stable electrochemical window of water, instability of electrode materials, undesired side reactions, etc. In recent years, a massive effort is devoted to overcoming the drawbacks, and some encouraging works have arisen. In this review, the latest advances of electrolyte and electrode materials in aqueous batteries based on monovalent ion (Li+, Na+, K+) and multivalent ion (Zn2+, Mg2+, Ca2+, Al3+) are briefly reviewed.

Zinc batteries were invented in the eighteenth century, but are still in widespread use as primary commercial batteries known as aqueous alkaline batteries. In this article, we discuss the state of the art of rechargeable aqueous zinc batteries. On the one side of the battery cell, porous zinc metal electrodes offer high energy and power densities. On the other side, zinc‐air batteries perform oxygen electrocatalysis in air electrodes, while zinc‐ion batteries use intercalation electrodes. These electrodes are connected by aqueous alkaline or aqueous neutral electrolytes. We introduce the basic history, concepts, and challenges of each technology. Our overview is spiced with some details of current research.
