Abstract
Provided is a battery system in which an interior part of a battery structure includes particles (phase-change particles) containing materials (phase-change materials) having a high latent heat of phase change at a specific temperature, contained in a capsule 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.
