In virtue of the high photoluminescence quantum yield(PLQY), tunable bandgap, facile synthesis, strong light-absorption ability and high defect tolerance, all inorganic perovskites CsPbX3（X=Cl, Br, I) hold a great promise in optoelectronic and photovoltaic fields, such as solid-state lighting, lasing, solar cell, and display etc. Despite the impressive achievements, the existing inorganic perovskites still receive strong criticism for the lack of thermal stability. This is because their poor thermal stability will observably reduce the durability, reliability, and long-term stability of optoelectronic devices. Herein, in this review, the influence of temperature on the stability of inorganic perovskites is discussed. The reasons behind the thermal decomposition of inorganic perovskites including the desorption of the surface ligands and phase transition under high temperatures are analyzed as well. Subsequently, the recent strategies towards enhancing the thermal stability of CsPbX3, such as ions doping, surface passivation, and composite structure, are emphatically reviewed. Furthermore, the performance parameters of optoelectronic perovskites-devices with high reliability reported so far are presented. Finally, we summarize and prospect the challenge and opportunity for future development of thermally stable inorganic perovskite CsPbX3.
