CYLINDRICAL LITHIUM ION SECONDARY BATTERY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18520350 titled 'CYLINDRICAL LITHIUM ION SECONDARY BATTERY
Simplified Explanation
The present invention is a cylindrical lithium ion secondary battery designed to prevent deformation of the cap assembly when the upper end of the cylindrical can is clamped, thus improving safety.
- The cylindrical lithium ion secondary battery comprises:
- A cylindrical can - An electrode assembly inside the can - A cap assembly for sealing the can - The cap assembly includes a top plate with a notch, a support plate with a first through-hole, and a bottom plate connected to the electrode assembly through the first through-hole - The support plate has a greater strength than the top plate
Potential Applications: - Electric vehicles - Portable electronic devices - Energy storage systems
Problems Solved: - Preventing deformation of the cap assembly - Improving safety of lithium ion batteries
Benefits: - Enhanced safety - Increased reliability - Longer lifespan of batteries
Potential Commercial Applications:
- Improving Safety and Performance of Cylindrical Lithium Ion Batteries ###
Possible Prior Art: - Prior art related to cap assemblies in cylindrical lithium ion batteries - Prior art on preventing deformation in battery components
Unanswered Questions:
- How does the strength of the support plate prevent deformation of the cap assembly?
Answer: The support plate's greater strength helps distribute pressure evenly, preventing deformation when the can is clamped.
- What specific safety improvements are achieved by preventing deformation of the cap assembly?
Answer: By preventing deformation, the risk of internal damage or short circuits in the battery is reduced, enhancing overall safety.
Original Abstract Submitted
The present invention relates to a cylindrical lithium ion secondary battery which, when an upper end of a cylindrical can is clamped, can prevent deformation of a cap assembly so as to improve safety. For an example, a cylindrical lithium ion secondary battery is disclosed, the battery comprising: a cylindrical can; an electrode assembly received in the cylindrical can; and a cap assembly for sealing the cylindrical can, wherein: the cap assembly comprises a top plate having a notch formed thereon, a support plate disposed in close contact with a lower surface of the top plate and including a first through-hole formed through the center thereof, and a bottom plate electrically connected with the electrode assembly and connected to the lower surface of the top plate through the first through-hole; and the support plate has a strength greater than a strength of the top plate.
