Thermal radiation coating and preparation method thereof, battery and electric device

The invention discloses a thermal radiation coating and a preparation method thereof, a battery and an electric device, and relates to the technical field of batteries. The thermal radiation coating comprises a heat absorption pigment, an insulating thermal radiation material and a film forming substance, the heat absorption pigment can absorb heat, and the insulating thermal radiation material can dissipate heat. The insulating thermal radiation coating prepared from the thermal radiation coating has good heat absorption, heat dissipation and insulation performance, is applied to battery protection, for example, the outer side of a battery shell is coated with the insulating thermal radiation coating, heat generated in a battery can be absorbed, then the absorbed heat is dissipated into the environment in a thermal radiation mode, and the situation that the battery is damaged due to temperature rise is prevented. According to the present invention, the thermal runaway phenomenon caused by the damage of the t
