Abstract

This review summarizes the recent findings regarding photoinvolved oxygen cathodes, battery configurations, and the stability of Li–O2 batteries, and aims to provide a fundamental understanding of photoinvolved Li–O2 batteries.

Tailored Plasmonic Ru/OV-MoO2 on TiO2 Catalysts via Solid-Phase Interface Engineering: Toward Highly Efficient Photoassisted Li–O2 Batteries with Enhanced Cycling Reliability

“…Compared with Ru/O V -MoO 2 (1 1 0) and TiO 2 (1 1 0) alone, the spatially separated photoelectrons gathered on Ru/O V -MoO 2 (1 1 0) (high CB) and TiO 2 (1 1 0) (low VB) optical holes make the electrode have stronger oxidation and reduction capabilities. 67,68 This corresponds to our experimental results and photocatalytic mechanism.…”

Historical development and novel concepts on electrolytes for aqueous rechargeable batteries

“…The introduction of light has been demonstrated to boost the reaction kinetics of the ORR/OER, leading to enhanced electrochemical performances. 275 Therefore, the synergic effect of electricity and light can cultivate thermodynamically and kinetically better ZABs, if the theoretical understanding of the photoelectrochemical process at oxygen cathodes is deeper, whilst relevant characterization technology becomes more advanced. Overall, aqueous energy storage systems have been extensively investigated through the development of novel electrolyte concepts, while there are still challenges to be tackled before their large-scale applications.…”

Integrated Photovoltaic Charging and Energy Storage Systems: Mechanism, Optimization, and Future

“…[75,76] To improves the photostability and resistibility to light corrosion of the material, the photoelectrodes structure integrating narrow-gap semiconductors with cocatalyst layer and electron-hole transport layer. [77][78][79] For example, Maity et al formed a p-n junction through the integration between p-ZnCo 2 O 4 and n-ZnO nanorods, a type II-like band alignment would occur, which accelerated charge separation and transfer, significantly reducing the photogenerated electron-hole pair compound and improve stability (Figure 5a). [80] Kim et al used electrochemical deposition to deposit an Au layer on a p-n junction composed of Cu 2 O/Ga 2 O 3 , and then formed a Ni-based cocatalyst.…”
