the buffer member is provided between the first battery cell and the second battery cell and/or is provided on a side of the first battery cell away from the second battery cell; the temperature collection member is provided between the first battery cell and the buffer member for collecting a temperature of the first battery cell; the temperature collection member is of a sheet structure, and a thickness direction of the temperature collection member is parallel to a stacking direction of the first battery cell and the second battery cell. ## Claims ### Claim 1 A battery, comprising: a first battery cell and a second battery cell stacked together; a buffer member, provided between the first battery cell and the second battery cell and/or provided on a side of the first battery cell facing away from the second battery cell; and a temperature collection member, provided between the first battery cell and the buffer member, for collecting a temperature of the first battery cell; wherein the temperature collection member has a sheet structure, a thickness direction of the temperature collection member is parallel to a stacking direction of the first battery cell and the second battery cell. ### Claim 2 (depends on 1) The battery according to claim 1, wherein the buffer member is provided with an accommodation cavity; the temperature collection member comprises a body and two protrusions, the two protrusions are formed on two surfaces of the body opposite to each other along the stacking direction; and along the stacking direction, among the two protrusions, one protrusion closer to the buffer member has a projection on the buffer member located in the accommodation cavity. ### Claim 3 (depends on 2) The battery according to claim 2, wherein the projection of the one protrusion along the stacking direction and a projection of the other of the two protrusions along the stacking direction overlap on the body; a dimension of the temperature collection member along the stacking direction at the corresponding position of the two protrusions is larger than the dimension of the temperature collection member at other positions. ### Claim 4 (depends on 3) The battery according to claim 3, wherein the battery further comprises: a mounting plate, provided between the first battery cell and the buffer member; the mounting plate comprising a mounting groove, the mounting groove penetrating through the mounting plate in a thickness direction of the mounting plate, a thickness direction of the mounting plate being parallel to the stacking direction, and the temperature collection member being provided in the mounting groove. ### Claim 5 (depends on 4) The battery according to claim 4, wherein the mounting groove forms a first opening at an edge of the mounting plate, and the temperature collection member is inserted into the mounting groove through the first opening. ### Claim 6 (depends on 4) The battery according to claim 4, wherein a hardness of the mounting plate is greater than a hardness of the buffer member. ### Claim 7 (depends on 4) The battery according to claim 4, wherein a central area of the mounting plate is provided with a first through hole; along the stacking direction, the first through hole penetrates through the mounting plate. ### Claim 8 (depends on 7) The battery according to claim 7, wherein the buffer member is provided with a second through hole; along the stacking direction, the second through hole penetrates through the buffer member, and a projection of the first through hole on the buffer member at least partially overlaps the second through hole. ### Claim 9 (depends on 4) The battery according to claim 4, wherein the temperature collection member has a maximum thickness of h1 and the mounting plate has a thickness of h2, and h2
