Problems solved by technology

However, since the fire extinguishing tank is evenly arranged on the upper part of the entire power battery box of the electric vehicle, when a single cell is thermally out of control, it will evenly sprinkle the fire extinguishing liquid in the inner space of the box, and it is impossible to guarantee that the fire extinguishing liquid will be targeted at a certain single cell. A sufficient do

Abstract

The invention discloses an aerosol honeycomb board for preventing thermo-runaway extension of a power battery, and belongs to the technical field of power battery security. The aerosol honeycomb boardcomprises a honeycomb ceramic layer, wherein the honeycomb ceramic layer is filled with an extinguishant; a bonding layer, an insulating flame-retardant paper layer and an insulating flame-retardantthin film layer are symmetrically arranged in sequence on two sides of the honeycomb ceramic layer from inside to outside. The invention further provides application of the aerosol honeycomb board toa battery module structure. Through the structure and material design of the aerosol honeycomb board, the aerosol honeycomb board can be applied to the structure design of a power battery module by replacing the conventional PC board, so that heat transmission can be cut off effectively according to a thermo-runaway extension mechanism, and the probability of an security accident of the thermo-runaway extension is lowered greatly.

Description

technical field [0001] The invention relates to an aerosol honeycomb panel for preventing thermal runaway expansion of a power battery and an application thereof, belonging to the technical field of power battery safety. Background technique [0002] The safety of power batteries is one of the most concerned issues in the process of large-scale promotion and application of new energy vehicles. [0003] The safety issues of the power battery system are mainly divided into three levels, namely "evolution", "triggering" and "expansion". "Evolution" means that before the power battery safety accident occurs, the fault may have experienced a long-term evolution process; "trigger" is the turning point of the "evolution" process, and it can also be an unexpected situation that destroys the power battery system and leads to a safety accident . Generally, after entering the trigger stage, the energy inside the lithium-ion power battery will be released concentratedly in an instant....
