The present invention relates to a battery module, which includes one or more battery cell units, and the battery cell unit includes a battery cell, a fixing member located surrounding an outer circumference surface of the battery cell, and a heat absorbing material located between the battery cell and the fixing member, and as a result, heat generation inside the battery module is suppressed, and ignition between the series-connected battery cell units may be suppressed. Accordingly, excellent charge and discharge efficiency, an excellent cycle property and a lifespan property of the battery may be exhibited without concern for explosion or ignition of the battery module.
