Here, we demonstrate the ability to continuously tune the thermal conductivity of nanoscale films of $\\rm La_{0.5}Sr_{0.5}CoO_{3-\\delta}$ (LSCO) by a factor of over 5, via a room-temperature electrolyte-gate-induced non-volatile topotactic phase transformation from perovskite (with $\\delta \\approx 0.1$) to an oxygen-vacancy-ordered brownmillerite phase (with $\\delta=0.5$), accompanied by a metal-insulator transition.
