摘要

•A new class of portable photoassisted Lithium-ion battery (PA-LIB) is constructed.•Transition metal sulfide heterojunction is used as a photoelectrode in PA-LIB.•Photoassisted charging/discharging processes are more energy-saving.•Photoinduced Li-ion de-intercalation and Ni valence conversion are revealed.•PA-LIB shows excellent stability and enhanced charge-discharg capacity.
