SEALED BATTERY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240014488 titled 'SEALED BATTERY

Simplified Explanation

The abstract describes a sealed battery design that includes a battery case with an opening, a closing plate that seals the opening, and a collector terminal with an external connector exposed on the outer surface of the closing plate. A resin insulator is used to insulate the closing plate and the external connector from each other. A laser-welded region is formed on the fitted portion between the battery case and the closing plate. Additionally, a shield is placed on the outer surface of the closing plate, interposed between the insulator and the fitted portion. The shield includes an inclined portion that defines a side face adjacent to the fitted portion.

  • The patent application describes a sealed battery design with improved sealing and insulation features.
  • The battery case has an opening that is closed by a closing plate, ensuring a sealed enclosure.
  • A collector terminal with an external connector is exposed on the outer surface of the closing plate, allowing for easy connection.
  • A resin insulator is used to insulate the closing plate and the external connector, preventing electrical contact.
  • A laser-welded region is formed on the fitted portion between the battery case and the closing plate, ensuring a secure and durable connection.
  • A shield is placed on the outer surface of the closing plate, providing additional insulation and sealing.
  • The shield includes an inclined portion that defines a side face adjacent to the fitted portion, enhancing the sealing properties.

Potential Applications:

  • Sealed batteries can be used in various electronic devices, such as smartphones, laptops, and electric vehicles.
  • The improved sealing and insulation features can enhance the safety and performance of the batteries in these devices.

Problems Solved:

  • The design addresses the need for a reliable and secure sealing mechanism in sealed batteries.
  • It solves the problem of electrical contact between the closing plate and the external connector, preventing short circuits.
  • The shield helps to protect the battery from external elements and further improves the sealing properties.

Benefits:

  • The improved sealing and insulation features ensure a longer lifespan for the battery by preventing damage from external factors.
  • The secure connection between the battery case and the closing plate enhances the overall durability of the battery.
  • The design simplifies the manufacturing process by utilizing laser welding and a resin insulator.
  • The exposed external connector allows for easy and convenient connection to external devices.


Original Abstract Submitted

a sealed battery includes: a battery case including an opening; a closing plate closing the opening; a collector terminal including an external connector exposed at an outer surface of the closing plate; a resin insulator insulating the closing plate and the external connector from each other; a laser-welded region formed on a fitted portion between the battery case and the closing plate; and a shield disposed on the outer surface of the closing plate. the shield is interposed between the insulator and the fitted portion. the shield includes an inclined portion inclined toward the fitted portion. the inclined portion defines a side face of the shield adjacent to the fitted portion.
