Abstract
There is disclosed a battery module including a first heat insulator formed in an insulation pad shape and disposed between battery cells; and a second heat insulator disposed between electrode leads and made of a material having a higher coefficient of thermal expansion than that of the first heat insulator, thereby blocking heat and high-temperature particles from moving between the respective battery cells and a bus bar plate and effectively reducing a risk of fires and explosions.
Claims10
A battery module comprising:
- a battery cell layered body formed by layering a first battery cell and a second battery cell that are adjacent to each other;
- a plurality of electrode leads electrically connected to the first battery cell and the second battery cell, respectively;
- a first heat insulator disposed between the first battery cell and the second battery cell;
- and
- a second heat insulator disposed between the plurality of electrode leads,
- wherein the second heat insulator is made of a material having a higher coefficient of thermal expansion than that of the first heat insulator.
