[0050] Specifically, a plurality of batteries 21 constitute at least one battery pack 2, and in the embodiment of the present application, four battery packs 2 are taken as an example for illustration, wherein each battery pack 2 includes five batteries 21. Correspondingly, the number of battery compartments 11 is four, each battery compartment 11 includes five battery mounting positions 117, and each battery mounting position 117 has a first opening 111 and a second opening 112 at both ends. Among them, five adjacent first openings 111 are connected to form an opening 11a, or five adjacent second openings 112 are also connected to form an opening 11a, a total of four openings 11a are formed and located on opposite sides of the energy storage shell 1, and two groups of openings 11a on the same side are arranged at intervals; due to the large opening of the opening 11a, it is easier to insert the battery 21 into the battery mounting position 117 when installing the battery 21, thereby facilitating the battery pack 2 to slide into the battery compartment 11 along the preset axial direction Z, and thereby improving the assembly efficiency of the battery pack 2. Among them, the direction of the preset axial direction Z is the same as the axial direction of the battery mounting position 117. In this way, after installing the battery pack 2 on one side, the corresponding first electrode sheet or second electrode sheet can be installed, and then after installing the battery pack 2 on the other side, the corresponding second electrode sheet or first electrode sheet is installed, thereby improving the assembly efficiency.

[0051] In order to ensure the independence of each battery 21 after the battery 21 is installed in the battery mounting position 117, and to ensure heat dissipation and safety, a baffle 118 is arranged between the battery mounting positions 117 in each battery compartment 11 to separate each two battery mounting positions 117 in each battery compartment 11; in order to ensure the installation efficiency of the battery 21, the length of the baffle 118 along the preset axial direction Z is less than the length of the side wall of the battery compartment 11 along the preset axial direction Z, that is, the baffle 118 extends along the preset axial direction Z in the battery mounting position 117 between the first opening 111 and the second opening 112, and the length is less than the distance length between the first opening 111 and the second opening 112. Specifically, in the embodiment, the length of the baffle 118 is about half the depth of the battery mounting position 117.
