Herein, carbon cloth-supported TiO_(2)nanorod arrays are engineered as a model platform to explore photoelectrochemical synergy in integrated photo-rechargeable lithium-ion batteries(PRLiBs). Through operando characterizations and theory calculations, we found that photoexcitation lowers the Li^(+)migration barrier by 0.16 eV through electronic states redistribution near the Fermi level,thereby accelerating Li^(+)transport and enhancing the intercalation process during photo-assisted charging and discharging. Three key principles governing dual operational modes(light-assisted charge/discharge and pure light charging) are established for PRLiBs:(i) the capacity enhancement during photoassisted charging is primarily due to photocatalytic Li^(+)extraction via hole-driven oxidation at the TiO_(2)/electrolyte interface and electric double-layer reconstruction;(ii) the long-standing controversy in solar-to-electricity conversion efficiency(g) is resolved by introducing a polarization-decoupled model to quantify g, distinguishing genuine catalytic contributions from parasitic self-charging effects;and(iii)during light-only charging without external bias, the capacity increase is predominantly driven by the photocatalytic oxidation of the TiO_(2)photoelectrode, a single-electrode process without electron transfer through an external circuit, distinct from conventional dual-electrode charging. This work lays a solid theoretical foundation for understanding the mechanisms of PRLiBs and provides precise guidelines for g calculations, offering valuable insights for the future development of photo-energy storage devices.展开更多
