Anhydrous electrolyte cell

本发明的目的是迅速散去在正极和负极之间发生短路时产生的热量。所公开的无水电解质电池包括单元电池位于其中的由层叠膜构成的密封介质，其特征在于密封介质的层叠膜含有具有在室温时为230Wm#+[-1]K#+[-1]或更高的导热率k的金属材料。而且，密封介质的金属材料部分的体积与单元电池的1mAh的容量的比值R为0.0002cm#+[3]/mAh≤R≤0.05cm#+[3]/mAh。 It is an object to quickly disperse heat generated when short circuit occurs between a positive electrode and a negative electrode. A nonaqueous-electrolyte battery is disclosed which incorporates: an encapsulating medium (2) constituted by a laminated film in which a unit cell (1) is accommodated, wherein the laminated film of the encapsulating medium contains a metal material having a heat conductivity k at room temperatures which is 230WmK or higher. Moreover, ratio R of the volume of the metal material portion of the encapsulating medium with respect to a capacity of 1mAh of the unit cell is 0.0002cm /mAh ≤ R ≤ 0.003cm /mAh.
