Energy dissipation has always been an attention-getting issue in modern electronics and the emerging low-symmetry two-dimensional (2D) materials are considered to have broad prospects in solving the energy dissipation problem. Herein the thermal transport of a typical 2D ternary chalcogenide Ta2NiS5 is investigated. For the first time we have observed strongly anisotropic in-plane thermal conductivity towards armchair and zigzag axes of suspended few-layer Ta2NiS5 flakes through Raman thermometry. For 7-nm-thick Ta2NiS5 flakes, the
