The light-assisted strategy is considered as an effective way to reduce the overpotential of lithium-oxygen (Li─O 2) batteries, however, the generated solid discharge products are prone to cover active sites of the solid-state photocatalyst, causing the premature death of the cell.
Li-O 2 batteries are mainly based on the chemical reaction of 2Li + O 2 ↔ Li 2 O 2 (E0 = 2.96 V), with energy density of 11 700 Wh kg −1 (without considering the mass of oxygen). [4 - 6] The essence of Li-O 2 batteries is the formation and decomposition of lithium peroxide in the process of discharge and charge.
With the simple in situ growth of Ce-UiO-66 on carbon cloth as an integrated photocathode, the photoassisted Li-O 2 batteries display decent discharge and charge voltages of 3.1 and 3.6 V, and a lifespan of 160 cycles.
Upon illumination, the discharge and charge voltages of Li-O 2 batteries with integrated photocathode were stable at 3.1 and 3.6 V, respectively, in contrast with 2.8 and 4.0 V for dropping photocathode. Furthermore, the batteries showed stable operation up to 160 cycles, which is three times longer than the batteries with dropping photocathode.
The light-assisted Li-O 2 battery was assembled with a Li foil anode, a glass fiber filter (Whatman GF/A) encapsulated with the electrolyte, and Ce-UiO-66 photocathode as an oxygen electrode and photocathode in a 2032-type coin cell with a 10 mm hole on the cathode shell as windows for illumination and O 2 diffusion.
Photoassisted Li-O 2 batteries were assembled with photocathodes as air cathodes in 2032-type coin cells with 10 mm holes in the cathode shells for illumination and O 2 diffusion, and a cold light from xenon lamp served as the light source to eliminate the temperature influence as much as possible.
