<p>PURPOSE: A secondary battery pack is provided to stably maintain and protect each unit cells, thereby capable of preventing flow of unit cells due to physical impact applied from outside. CONSTITUTION: A secondary battery pack comprises: unit cells(10) arranged to be neighboring each other; a case accepting the unit cells while supporting sides of the unit cells; and a spacer elastically supporting the unit cells by being compressed between the unit cells. The case comprises a support part corresponding with sides of the unit cell to support the unit cells against elasticity of the spacer. The spacer comprises a pair of pressing parts(33) formed on both sides of a first direction to press the unit cells, and an elastic part(34) elastically connecting the pressing parts.</p> |
