Photo-assisted charge/discharge Li-organic battery with a charge-separated and redox-active C₆₀@porous organic cage cathode

Abstract

Photo-assisted Li-organic batteries provide an attractive approach for solar energy conversion and storage, while the challenge lies in the design of high-efficiency organic cathodes. Herein, a charge-separated and redox-active C60@porous...

Advances and Challenges in Photoelectrochemical Redox Batteries for Solar Energy Conversion and Storage

“…[ 70 ] Therefore, consideration of utilizing the full‐spectrum solar energy and promoting the separation and utilization of charge carriers is largely required. [ 30c,71 ]…”

An integrated solar battery based on a charge storing 2D carbon nitride

“…V 2 O 5 , 18,19 MoO 3 , 20 TiO 2 , 21 or 2D perovskites 22 ) and organic ( e.g. covalent organic frameworks, 23 quinone derivatives, 24 or porous organic cages 25 ). Notably, all existing device designs rely on transfer of the photogenerated charge carriers to the anode or cathode via an electrolyte or additional external circuit during charging, with the separator between the electrodes acting solely to conduct ions and prevent a short circuit, inspired by traditional battery designs, and thus resemble integrated PV-batteries.…”

External field–assisted batteries toward performance improvement

“…10 Gradually, using light to address the high reaction barriers has extended to various metal-air/CO 2 batteries, for example, Li-CO 2 , 11,12 and zinc-air. 13,14 With tremendous efforts devoted to constructing photo-assisted rechargeable batteries based on two-electrode systems, the photo-assisted high-performance Li-S, 15 Li-I 2 , 16 and Li-organic 17 batteries have also been successfully fabricated recently. The external magnetic field has also attracted attention due to the potential to solve the dendrite growth problem and improve battery performance.…”
