In Situ Light-Modulation of Capacity and Impedance in Lithium-Ion Batteries.

ABSTRACT: The in situ regulation of capacity and impedance presents a significant challenge that impedes the application of lithium-ion batteries (LIBs). Herein, a novel strategy is introduced that utilizes a broadband light-modulated method for in situ manipulation of cell capacities and impedances. This approach leverages a photoconductive heterojunction comprising cadmium sulfide (CdS) nanorod arrays and a reduced graphene oxide (rGO) film. The heterostructure efficiently responds to a broad light spectrum, including UV to visible wavelengths. The results show that for the CdS/rGO anode, under conditions of UV exposure and absence of illumination, the capacity varies between 275 and 450 mAh g^-1 after 200 cycles at 0.2 A g^-1, and the impedance changes from 1205 to 261 Ω, resp
