Abstract
The battery module according to one embodiment of the present disclosure includes: a battery cell stack, in which a plurality of battery cells comprising electrode leads, are stacked; busbars connecting the electrode leads; and a temperature control unit that makes contact with the electrode leads. The temperature control unit comprises a heat transfer member that makes contact with the electrode leads and a thermoelectric element capable of being heated and cooled, wherein the heat transfer member comprises a metal layer and a metal oxide layer, the metal oxide layer being located between the metal layer and the electrode leads.
Claims11
A battery module comprising:
- a battery cell stack, in which a plurality of battery cells each comprising respective electrode leads, are stacked;
- a busbar connecting a plurality of the electrode leads together;
- and
- a temperature control unit arranged to contact the plurality of electrode leads,
- wherein the temperature control unit comprises a thermoelectric element capable of being heated and cooled and a heat transfer member, the heat transfer member arranged to contact the electrode leads, and the heat transfer member being positioned between the electrode leads and the thermoelectric element so as to space the thermoelectric element away from the electrode leads such that
- the thermoelectric element does not directly contact the electrode leads, and
- wherein the heat transfer member comprises a metal layer and a metal oxide layer, the metal oxide layer being disposed on a surface of the metal layer between the metal layer and the electrode leads such that the metal oxide layer is in direct contact with the electrode leads while the metal layer is not in direct contact with the electrode leads.
