Abstract
A battery module, includes a battery cell stack in which a plurality of battery cells are stacked; and a heat dissipation plate coupled to one side of the battery cell stack to discharge heat generated in the battery cells externally. The battery cell stack includes a first blocking member formed of an insulating material and disposed between the plurality of battery cells to provide a plurality of insulating spaces. The plurality of battery cells are distributedly disposed in the plurality of insulating spaces.
Claims16
A battery module, comprising:
- a battery cell stack in which a plurality of battery cells having electrode leads are stacked in a first direction;
- and
- a heat dissipation plate coupled to at least one side of the battery cell stack to discharge heat generated in the battery cells externally,
- wherein the battery cell stack comprises a first blocking member including a thermal insulation material and disposed between the plurality of battery cells,
- wherein the first blocking member encompasses at least one side surface of each of the plurality of battery cells to provide a plurality of thermally insulated spaces,
- wherein each of the plurality of battery cells includes:
- a first sealing portion in which at least one of the electrode leads is disposed;
- and
- a second sealing portion in which the electrode leads are not disposed,
- wherein the plurality of battery cells are distributedly disposed in the plurality of thermally insulated spaces, and
- wherein the first blocking member includes:
- a first portion disposed between the plurality of battery cells;
- and
- a second portion extending from the first portion, and facing the heat dissipation plate and the second sealing portion.
