an adhesive having a thermal conductivity of more than 0.4 W/mK (0.96×10 −3 cal/cm·sec·° C.) is provided at a gap between said plurality of secondary batteries and said outer case and including metal powder of more than 20 wt %.
2. A battery pack including a plurality of secondary batteries within an outer case comprising:
a gel filler having a thermal conductivity of more than 0.4 W/mK (0.96×10 −3 cal/cm·sec·° C.) is provided at a gap between said plurality of secondary batteries and said outer case.
3. A battery pack including a plurality of secondary batteries within an outer case comprising:
a gel sheet having pressure deformable gel function and having a thermal conductivity of more than 0.4 W/mK (0.96×10 −3 cal/cm·sec·° C.) is provided at a gap between said plurality of secondary batteries and said outer case.
4. A battery pack including a plurality of secondary batteries within an outer case comprising:
a pressure deformable flat rubber sheet having a thermal conductivity of more than 0.4 W/mK (0.96(10−3 cal/cm·sec·° C.) is provided at a gap between said plurality of secondary batteries and said outer case.
