Provided is a battery system in which an interior part of a battery structure includes phase-change particles including a capsule and phase-change materials. The phase-change materials have a high latent heat of phase change at a specific temperature, and are encapsulated in the capsule. The capsule is made of an inert material. The battery system in accordance with the present invention can prolong a service life of the battery by inhibiting temperature elevation inside the battery under normal operating conditions without substantial effects on size, shape and performance of the battery, and further, can inhibit the risk of explosion resulting from a sharp increase in temperature inside the battery under abnormal operating conditions, thereby contributing to battery safety. |
