AI Technical Summary
Technical Problem
In existing battery module designs, the pressure relief structure does not take into account the direction of gas jets, which can easily cause damage to adjacent cells and affect the safety of the battery pack.
Method used
Design a pressure relief structure including a shell and a sealing element. The shell has a first channel with alternating vertical and horizontal channels inside. The sealing element controls the conduction and blocking state of the gas to ensure that the gas flows along a specific trajectory and avoids irregular jetting.
Benefits of technology
This allows for the directional extraction of gas, avoiding damage to adjacent cells and improving battery safety and stability.

Abstract
The utility model discloses a kind of pressure relief structure and novel battery, pressure relief structure includes shell and first plugging, first passage is formed in shell interior, one end of first passage and air inlet are communicated, other end and air outlet are communicated, first passage includes at least one vertical passage and horizontal passage, vertical passage and horizontal passage are sequentially arranged alternately, and vertical passage and horizontal passage are connected at angle. Compared with the related art, gas in battery enters first passage from air inlet, passes through alternately arranged multiple vertical passages and multiple horizontal passages, since every vertical passage and every horizontal passage is set at angle, for example, when vertical passage and horizontal passage are perpendicularly set each other, then first passage forms multiple continuous rectangular channels, gas in first passage will flow along the inner wall of rectangular channel, to realize that gas flows along specific trajectory, realize the effect of directional export, avoid irregular gas jet.
