Abstract
A protection structure for preventing thermal dissipation and thermal runaway diffusion in battery system is provided. The protection structure includes a battery module casing and at least one composite heat conduction plate. There is a plurality of unit cells disposed in the battery module casing. The composite heat conduction plate is located within the battery module casing, contacted with the battery module casing, and sandwiched between at least two of the unit cells as a heat transmission medium between the cells and the casing to control heat transmission among the cells. The composite heat conduction plate is a multilayer anisotropic heat conduction structure constituted by at least one heat conduction layer and at least one heat insulation layer.
