Definitions

  • the present inventor found that the above problems can be solved by a battery module including a silicone matrix and a heat-absorbing member containing a specific amount of aluminum hydroxide with a small particle size, and completed the present invention.
  • the present invention provides the following [1] to [7].
  • the viscosity of the heat-absorbing composition for manufacturing the heat-absorbing member is lowered to improve workability, and a certain amount or more of aluminum hydroxide having a large particle size exceeding 5 ⁇ m, which will be described later, is added to improve the thermal conductivity.
  • the content of the small-diameter aluminum hydroxide in the heat-absorbing member is preferably 70% by volume or less, more preferably 50% by volume or less.
  • the volume ratio of small-diameter aluminum hydroxide to the total amount of aluminum hydroxide contained in the heat-absorbing member is preferably 26% by volume or more. This makes it easier to absorb heat of 300° C. or less for a long period of time.
  • the volume ratio of the small-diameter aluminum hydroxide to the total amount of aluminum hydroxide contained in the heat-absorbing member is more preferably 30% by volume or more, still more preferably 40% by volume or more, and still more preferably 50% by volume or more. .
  • the area ratio of the aluminum hydroxide having a particle size of more than 5 ⁇ m in the cross section is defined as the content (% by volume) of the large-diameter aluminum hydroxide having a particle size of more than 5 ⁇ m in the heat-absorbing member.
  • the particle size observed with an electron microscope is the diameter if the observed shape is a circle, and the maximum distance between any two points on the outer periphery of the observed shape if it is a shape other than a circle. do.
  • Examples 2 to 5, Comparative Examples 1 to 3 An endothermic member was produced in the same manner as in Example 1, except that the composition of the endothermic composition was changed as shown in Table 1, and each evaluation was performed. Table 2 shows the results. It should be noted that the viscosities of the endothermic compositions of Example 4 and Comparative Example 3 could not be measured.
