BUTTON-TYPE SECONDARY BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240021928 titled 'BUTTON-TYPE SECONDARY BATTERY

Simplified Explanation

The abstract describes a button-type secondary battery that consists of a lower can and an upper can, with an electrode assembly placed in the accommodation space between them. The lower can has a first planar part where the electrode assembly is seated, and a first sidewall with a concave portion. The upper can has a second planar part that covers the top surface of the lower can, and a second sidewall with a convex portion on its inner surface. When the sidewalls are coupled, the convex portion fits into the concave portion.

  • The patent is for a button-type secondary battery design.
  • The battery includes a lower can and an upper can that are coupled together.
  • An electrode assembly is placed in the space between the lower and upper cans.
  • The lower can has a first planar part and a first sidewall with a concave portion.
  • The upper can has a second planar part and a second sidewall with a convex portion.
  • When the sidewalls are coupled, the convex portion fits into the concave portion.

Potential applications of this technology:

  • Button-type secondary batteries can be used in various electronic devices such as smartphones, tablets, and smartwatches.
  • The design allows for efficient use of space and can be integrated into compact devices.

Problems solved by this technology:

  • The design ensures a secure and stable connection between the lower and upper cans, preventing any leakage or damage to the electrode assembly.
  • The concave and convex portions provide a tight fit, reducing the risk of any movement or displacement of the electrode assembly during operation.

Benefits of this technology:

  • The button-type secondary battery design offers improved safety and reliability.
  • The compact design allows for efficient use of space in electronic devices.
  • The secure connection between the lower and upper cans ensures the longevity and performance of the battery.


Original Abstract Submitted

a button-type secondary battery includes a lower can; an upper can is coupled to the lower can; an electrode assembly is on the lower can in an accommodation space defined between the lower can and the upper can. the lower can includes a first planar part, on which the electrode assembly is seated, and a first sidewall disposed vertically along a circumference of the first planar part such that a concave portion is defined in the first sidewall. the upper can includes a second planar part, which has an area that covers an opened top surface of the lower can, and a second sidewall disposed vertically along a circumference of the second planar part such that a convex portion is on an inner surface of the second sidewall. when the sidewall is coupled to be placed outside the first sidewall, the convex portion is fitted into the concave portion.
