Abstract Directly harvesting solar power without traditional cells represents an efficient solution to the current energy challenges. Photo‐rechargeable batteries (PRBs) are receiving intense interest as they eliminate additional costs and losses associated with off‐grid generation. Herein, photo‐rechargeable aqueous Zinc‐ion (PRZIBs) constructed, using α‐MnO 2 nanowires bifunctional photoelectrodes reveal complex photo‐electrochemical effects in MnO PRZIBs. Through a series of situ characterizations under illumination, advantages intrinsic light based PRZIBs elucidated from three aspects: (1) inhibition Jahn‐Teller distortion via strengthened hydrogen bonding within , (2) suppression Mn 2+ dissolution through “protective layers” formed by photo‐promoted Zn /H + co‐intercalation, (3) acceleration desolvation electrolyte enabled abundant photogenerated holes. The demonstrate specific discharge capacity 308.1 mAh g −1 illumination (1 sun), along excellent cycling stability high conversion efficiency 0.68% (by photocharging only). In addition, interdigital micro‐PRZIBs successfully wearable sensors, demonstrating practical applicability. This work provides valuable insights into time‐resolved reaction mechanisms PRZIBs, opens new prospects for developing PRBs portable devices, i.e. smart textiles biosensors.

1D transition metal dichalcogenide (TMD) nanowires (NWs) have attracted attention to act as energy storage and information technology materials, but the TMD NWs are unable directly synthesized rather than hexagonal flakes due habit of in-planar isotropic crystal growth. Herein, topological phase transformation is proposed synthesize ultralong high-quality 2H-MoS2 from a surface-to-interior sulfurization isomorphic Mo2S3 NWs. endows structure with [MoS] chains inserted into structure. The harvested MoS2 average in length >150 µm diameter ≈400 nm, electrical conductivity ≈150 S m-1 much higher reported (10-2 m-1).

Abstract Efficient and stable photocathodes with versatility are of significance in photoassisted lithium-ion batteries (PLIBs), while there is always a request on fast carrier transport electrochemical active photocathodes. Present work proposes general approach creating bulk heterojunction to boost the mobility by simply laser assisted embedding plasmonic nanocrystals. When employed PLIBs, it was found effective for synchronously enhanced photocharge separation light charging process. Additionally, experimental photon spectroscopy, finite difference time domain method simulation theoretical analyses demonstrate that improved dynamics driven plasmonic-induced hot electron injection from metal TiO 2 , as well conductivity matrix due formation oxygen vacancies after Schottky contact. Benefiting these merits, several benchmark values performance -based photocathode applied PLIBs set, including capacity 276 mAh g −1 at 0.2 A under illumination, photoconversion efficiency 1.276% 3 less Columbic loss even through 200 cycles. These results exemplify potential strategy developing highly efficient energy storage systems.
