Abstract: The present invention provides a retaining component, a battery assembly and an end structure. The retaining component of the present invention is configured to fix multiple cells at the top and/or bottom of the multiple cells, and a hole open to the outside is provided in the retaining component at a position corresponding to a fusible part, so that the fusible part is exposed. According to the present invention, the fusible part can be exposed to the outside at the opening; this provides space for melt-through of the fusible part. For example, when melt-through occurs due to current flow through the fusible part of a collector component, the structure of the opening allows the fusible part to melt through fully, thereby protecting the circuit.

Abstract: The present invention provides a battery support, and a battery assembly comprising the battery support. The battery support is used to retain a battery assembly having multiple cells; a heat dissipating means of the battery support comprises at least one spacer component, the spacer component has multiple accommodating recesses on at least one side, the accommodating recess is partially shape-fitted to a circumferential sidewall of the cell, and the spacer component is made of a material with a thermal conductivity greater than that of air. The heat dissipating means of the battery support of the present invention is fitted to outer walls of the cells over as large an area as possible, and the heat dissipating means is able to undergo heat exchange with the cells in the process of use of the battery assembly and thus promote heat dissipation from the cells, in order to maintain the efficiency of use and the service life of the battery assembly.
