BATTERY CELL, BATTERY, ELECTRIC APPARATUS, AND MANUFACTURING METHOD AND DEVICE OF BATTERY CELL - A simplified explanation of the abstract
This abstract first appeared for US patent application 18447429 titled 'BATTERY CELL, BATTERY, ELECTRIC APPARATUS, AND MANUFACTURING METHOD AND DEVICE OF BATTERY CELL
Simplified Explanation
The patent application describes a battery cell and its manufacturing method. It includes an electrode assembly, a casing with an accommodating cavity, an exhaust mechanism, and an electrolyte. The exhaust mechanism allows gas to be discharged from the casing when the internal gas pressure reaches a certain threshold. The gas permeability of the breathable component, the conductivity of the electrolyte, and the gas containment space must satisfy a specific range.
- The patent application describes a battery cell with an exhaust mechanism to release gas when the internal pressure reaches a threshold.
- The breathable component of the exhaust mechanism allows gas to be discharged outside the casing.
- The gas permeability of the breathable component, the conductivity of the electrolyte, and the gas containment space must satisfy a specific range.
- The battery cell also includes an electrode assembly and an electrolyte filled in the casing.
Potential applications of this technology:
- Electric vehicles: The battery cell with the described exhaust mechanism can be used in electric vehicles to ensure safe operation and prevent gas buildup.
- Portable electronics: This technology can be applied to battery cells used in smartphones, laptops, and other portable electronic devices to enhance safety and performance.
Problems solved by this technology:
- Gas buildup: The exhaust mechanism prevents gas buildup inside the battery cell, reducing the risk of explosion or damage.
- Safety concerns: By allowing gas to be discharged when the pressure reaches a threshold, the technology ensures the safe operation of the battery cell.
Benefits of this technology:
- Enhanced safety: The exhaust mechanism prevents gas buildup, reducing the risk of accidents and improving the overall safety of the battery cell.
- Improved performance: By maintaining optimal gas pressure inside the casing, the battery cell can operate efficiently and deliver better performance.
- Manufacturing efficiency: The manufacturing method and device described in the patent application allow for the efficient production of battery cells with the required exhaust mechanism.
Original Abstract Submitted
A battery cell, a battery, an electric apparatus, and a manufacturing method and manufacturing device of battery cell are described. The battery cell includes: an electrode assembly; a casing having an accommodating cavity for accommodating the electrode assembly; an exhaust mechanism provided on the casing, the exhaust mechanism including a connecting component and a breathable component, and the breathable component is configured to discharge gas to outside of the casing when gas pressure inside the casing reaches a threshold; and an electrolyte, filled in the casing; where gas permeability A of the breathable component, conductivity S of the electrolyte, and gas containment space V satisfy 20 mm*ms/cm*ml<AS/V<165 mm*ms/cm*ml, and the gas containment space V is a ratio of a remaining value of volume of the accommodating cavity minus volume of the electrolyte and volume of the electrode assembly to capacity of the electrode assembly.
