The present invention relates to a secondary battery pack and a vehicle comprising the same. Specifically, provided is a secondary battery pack comprising: one or more battery cells; and one or more structures which cover at least a part of the battery cells and are electrically insulated from the battery cells, wherein at least a part of the structures comprises a substance having a resistivity three times or less than the resistivity of at least one substance constituting a positive electrode collector of the battery cells. As a structure covering a battery cell, the secondary battery pack, according to the present invention, uses a substance having the same level of resistivity as a positive electrode collector. Thus, if the structure is brought into contact with the positive electrode collector through collisional destruction of the secondary battery pack, the structure, instead of the positive electrode collector, performs the function of a conductive path through which an electric current can flow, and thus it is possible to prevent ignition resulting from contact of the positive electrode collector with a negative electrode active material. Furthermore, application of the secondary battery pack to a vehicle results in an effect of securing high stability. |
