  "textContent": "The invention provides a battery module, which includes a plurality of batteries, an upper cover, and a pressing strip. The pressing strip covers an explosion-proof valve of a battery, and includes a main body portion and a bottom plate portion. The bottom plate portion is connected to the main body portion and forms an accommodating cavity together with the main body portion. A fire extinguishing agent is sealed in the accommodating cavity. The bottom plate portion of the pressing strip is configured to be melted. The fire extinguishing agent is constantly stored in the accommodating cavity of the pressing strip, so as to avoid wasteful use of the fire extinguishing agent caused by the same flowing in all directions, so that the amount of the fire extinguishing agent can be maintained at a constant level at all times. When a battery occurs a thermal runaway, a high-temperature substance in the battery can break through the explosion-proof valve. And at this time, the high-temperature substance can melt the bottom plate portion of the pressing strip and the fire extinguishing agent can be timely discharged from the accommodating cavity, thereby enabling the fire extinguishing agent to quickly flow into the interior of the battery to reduce the temperature therefore, preventing the diffusion of the thermal runaway, and greatly reducing the degree of the thermal runaway.",
