“…[93] CuO and Cu 2 O were also used to promote ORR process of an Al-air battery. [100] A Cu 2 O/CuCoCr-layered double hydroxide with ultrathin pn type heterojunction nanosheets was designed for a Zn-CO 2 battery. The heterostructure photocatalyst was beneficial to converting CO 2 to CO during discharging and water oxidation during charging.…”

Metal-air batteries are considered one of the most promising next-generation energy storage devices owing to their ultrahigh theoretical specific energy. However, sluggish cathode kinetics (O 2 and CO 2 reduction/evolution) result in large overpotentials and low round-trip efficiencies which seriously hinder their practical applications. Utilizing light to drive slow cathode processes has increasingly becoming a promising solution to this issue. Considering the rapid development and emerging issues of this field, this Review summarizes the current understanding of light-assisted metalair batteries in terms of configurations and mechanisms, provides general design strategies and specific examples of photocathodes, systematically discusses the influence of light on batteries, and finally identifies existing gaps and future priorities for the development of practical light-assisted metal-air batteries.

“…In alkaline and acidic electrolytes, the passivation lm is continuously dissolved, causing the Al anode to expose to the electrolyte and suffer from a severe hydrogen evolution reaction (HER). To address this issue, tremendous regulation strategies for the anode and electrolyte have been proposed, such as anodic alloying, [28][29][30] electrolyte additives, [31][32][33][34] solid electrolytes, [35][36][37] nonaqueous electrolytes, 38 high concentration electrolytes 39 and oil displacement. 40 Since the HER occurs at the interface between the electrolyte and electrode, and the electrolyte is an important component connecting the cathode and anode by ion transmission, it governs the battery electrochemistry.…”
