Battery Cell and Battery Module Comprising Same - A simplified explanation of the abstract
This abstract first appeared for US patent application 18036531 titled 'Battery Cell and Battery Module Comprising Same
Simplified Explanation
The patent application describes a battery cell with a unique sealing structure and a gas discharge guiding unit.
- The battery cell includes a battery case with an accommodation portion for an electrode assembly and a sealing portion that seals the outer periphery of the case.
- An electrode lead is electrically connected to an electrode tab in the assembly.
- A lead film is located at the sealing portion of the electrode lead.
- A gas discharge guiding unit is inserted in the lead film.
- The sealing portion consists of a first sealing portion on the gas discharge guiding unit and a second sealing portion on both sides of the first sealing portion.
- The width of the first sealing portion is smaller than the width of the second sealing portion, based on the protruding direction of the electrode lead.
Potential applications of this technology:
- Battery cells used in various electronic devices such as smartphones, laptops, and electric vehicles.
- Energy storage systems for renewable energy sources like solar and wind power.
Problems solved by this technology:
- Provides a reliable sealing structure for the battery cell, preventing gas leakage and improving safety.
- The gas discharge guiding unit helps to efficiently release any gas generated during battery operation.
Benefits of this technology:
- Enhanced safety due to improved sealing and gas discharge capabilities.
- Increased reliability and lifespan of the battery cell.
- Suitable for various applications and environments.
Original Abstract Submitted
Disclosed is a battery cell, which includes a battery case having an accommodation portion in which an electrode assembly is mounted, and a sealing portion formed by sealing an outer periphery thereof; an electrode lead electrically connected to an electrode tab included in the electrode assembly; and a lead film located at a portion corresponding to the sealing portion in at least one of an upper portion and a lower portion of the electrode lead, wherein a gas discharge guiding unit is inserted in the lead film, the sealing portion includes a first sealing portion located on the gas discharge guiding unit and a second sealing portion located at both sides of the first sealing portion, and based on a protruding direction of the electrode lead, a width of the first sealing portion is smaller than a width of the second sealing portion.
