The second limiting portion 14 is disposed on the second end surface 13s and partially overlaps with the second accommodating holes 13a, so that the second limiting portion 14 can block the battery cells 31 and prevent the battery cells 31 from detaching from the first end surface 13s. The battery housing module 10 . As shown in FIG. 1 , the second pressing portion 113 is pressed against the first limiting portion 12 . For example, each first limiting portion 12 has a second groove 12r2 intersecting with the first groove 12r1 , and the extending direction of the second groove 12r2 is the same as the extending direction of the second pressing portion 113 . The second pressing portion 113 passes through the second groove 12r2. The second groove 12r2 can restrain the movement of the second pressing portion 113 to prevent the second pressing portion 113 from easily deviating from the first battery accommodating module 10 . In addition, since the second groove 12r2 is recessed, the second pressing portion 113 located in the second groove 12r2 can press against the electrode sheet 32 to fix the relative position of the electrode sheet 32 and the battery core 31 .

As shown in FIG. 5, each of the first accommodating holes 11a accommodates the corresponding battery cells 31. A portion of the battery cell 31 is accommodated in each of the second accommodating holes 13a. In other words, the entire battery cell 31 is accommodated by the butted first accommodating frame 11 and the second accommodating frame 13 , and is constrained between the first limiting portion 12 and the second limiting portion 14 to prevent the battery cell 31 is easily separated from the first battery accommodating module 10 .
