Under photo-rechargeable conditions, a single cell can maintain an open-circuit voltage as high as 0.45 V in the absence of illumination. By connecting multiple cells in series, we succeed in powering an LED (Light-emitting diode) continuously for 1 min without light exposure.
We find that a direct exposure of light to an operating LiMn 2 O 4 cathode during charging leads to a remarkable lowering of the battery charging time by a factor of two or more. This...

Despite the seemingly simple concept, charging a battery electric truck can require a large amount of electricity in a very short period of time—this is amplified further when multiple vehicles need to refuel quickly. Understanding how to manage the tradeoffs between a powerful charger that can achieve 80% state of charge within 1.5 hours (e.g., a 250-kW charger) and a less

We find that a direct exposure of light to an operating LiMn2O4 cathode during charging leads to a remarkable lowering of the battery charging time by a factor of two or more. This enhancement is enabled by the induction of a microsecond long-lived charge separated state, consisting of Mn4+ (hole) plus electron.
Three cycles of charging (indicated in solid lines) and discharging (in dash lines) profiles between 3.2 and 4.4 V at a C/10 rate are shown. A photograph of a fabricated ‘open’ cell is shown in the inset
This could be explained by the now permitted photocharging mechanism occurring constantly as a background process. The result is an increase in the observed gravimetric capacity of the cell; however, here we show how this does not result in an increased number of charges stored in the electrode.
After light charging, the battery is discharged galvanostatically in either light or dark. As shown in Figure 5 d, the voltage increases to ∼2.82 V when illuminated for 5 h (λ ∼455 nm, intensity ∼12 mW cm –2), and this increases to ∼3.0 V after prolonged illumination (see Figure S11a).
