SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18243239 titled 'SECONDARY BATTERY
Simplified Explanation
The abstract describes a patent application for a secondary battery with a unique cap assembly design that includes a safety vent with specific notches for pressure release.
- Electrode assembly
- Case to hold the electrode assembly
- Cap assembly with cap up, safety vent, and cap down
- Safety vent with main notch and sub-notch
- Sub-notch depth smaller than main notch depth
Potential Applications
The technology could be applied in various electronic devices that use secondary batteries, such as smartphones, laptops, and electric vehicles.
Problems Solved
The design of the safety vent with specific notches helps in efficient pressure release during battery operation, reducing the risk of overpressure and potential safety hazards.
Benefits
- Enhanced safety features in secondary batteries - Improved reliability and performance - Potential for increased battery lifespan
Potential Commercial Applications
The technology could be of interest to battery manufacturers, electronic device manufacturers, and the automotive industry for the development of safer and more reliable battery solutions.
Possible Prior Art
One possible prior art could be existing secondary battery designs with safety vents, but the specific configuration of notches as described in this patent application may be a novel innovation.
Unanswered Questions
How does the depth of the sub-notch affect the overall performance of the safety vent?
The depth of the sub-notch plays a crucial role in determining the pressure release efficiency of the safety vent. A deeper sub-notch may allow for quicker pressure release but could also impact the structural integrity of the vent. Further research and testing would be needed to optimize this aspect of the design.
Are there any potential drawbacks or limitations to the specific notch configuration described in the patent application?
While the specific notch configuration may offer improved safety and performance benefits, there could be potential drawbacks such as increased manufacturing complexity or cost. Additionally, the effectiveness of the design in real-world conditions would need to be thoroughly evaluated to ensure its practicality and reliability.
Original Abstract Submitted
A secondary battery includes an electrode assembly; a case that accommodates the electrode assembly; and a cap assembly that is coupled to an upper portion of the case, the cap assembly including a cap up, a safety vent below the cap up, and a cap down below the safety vent and electrically connected to the electrode assembly, wherein the safety vent includes a main notch and a sub-notch adjacent to the main notch, and the sub-notch has a depth that is smaller than a depth of the main notch.
