    摘要： A battery relating to the field of batteries and comprising a battery module (2), a cooling liquid (11) and a battery container (1). The battery module (2) and cooling liquid (11) are each provided within the battery container (1), and the battery module (2) is at least partially immersed in the cooling liquid (11). A liquid sealing layer (12) comprising a barrier liquid covers the cooling liquid (11). The latent heat of vaporization of the cooling liquid rapidly carries away heat released by a battery undergoing thermal runaway, thereby avoiding a heat buildup which causes a constant spreading of battery thermal runaway, thus having a protective effect on the battery.

    摘要： The present invention is intended to provide a battery pack and a battery pack system. The battery pack comprises a battery box and a battery module. The battery module is disposed in the battery box. The battery module consists of a plurality of battery cells. The battery box is further filled with confining liquid. The battery module is at least partially soaked into the confining liquid. At least one cooling pipeline is disposed in the battery box. At least part of the cooling pipeline is molten and broken after reaching a pre-set temperature. The cooling pipeline is filled with cooling liquid. The vaporization latent heat of the cooling liquid is higher than or equal to the heat capacity or vaporization latent heat of the confining liquid. The technical solution provided by the present invention can effectively inhibit propagation of thermal runaway of a battery pack, and can save the interior space of a vehicle, thereby improving the energy density of the battery pack.
