The invention discloses a battery heat-insulation flame-retardant explosion-proof system, and relates to the technical field of battery heat management. The system comprises a matrix layer and an excitation material pipeline, wherein the matrix layer wraps a battery cell and is made of a foaming material, and the excitation material pipeline is arranged outside the matrix layer; and an excitation material used for exciting the foaming material to enable the foaming material to be subjected to phase change curing is stored in the excitation material pipeline, and the excitation material can automatically flow out of the excitation material pipeline under the action of a high temperature. The foaming material matrix layer is wrapped outside the battery, and heat transfer to adjacent batteries is reduced by utilizing the heat insulation property of the foaming material so that other batteries are prevented from being affected; meanwhile, by utilizing the heat absorption expansion performance of the foaming mater
