AI Technical Summary
Technical Problem
In the event of thermal runaway, existing battery cells suffer from electrolyte ejection and combustion, resulting in poor reliability and making it difficult to effectively reduce the risk of combustion.
Method used
Design a battery cell comprising a casing, electrolyte, pressure relief mechanism and atomizing component. The atomizing component atomizes the electrolyte in a preset state and sprays it toward the pressure relief mechanism. The atomized electrolyte absorbs heat and evaporates, reducing the risk of combustion.
Benefits of technology
By designing the atomizing components, the risk of combustion during thermal runaway of battery cells is significantly reduced, thereby improving the reliability and safety of battery cells.

Abstract
This application provides a battery cell, a battery device, an energy storage device, an energy storage system, and a charging network. The battery cell includes a casing, an electrolyte, a pressure relief mechanism, a collecting component, and an atomizing component. The casing has a receiving cavity and includes a first wall disposed on one side of the receiving cavity along a first direction. The electrolyte is contained within the receiving cavity, and the pressure relief mechanism is disposed on the first wall. The collecting component is connected to the side of the first wall facing the receiving cavity. The collecting component has a cavity body and an opening on the side of the collecting component facing the first wall, the opening communicating with the cavity body. The collecting component includes a side wall surrounding the opening, and a through hole is formed on the side wall, the through hole communicating with the cavity body and the receiving cavity. At least a portion of the atomizing component is disposed within the cavity body, and the atomizing component is configured to atomize the electrolyte and spray it toward the pressure relief mechanism when the battery cell reaches a preset state. According to this application, the reliability of the battery cell can be effectively improved.
