BATTERY MODULE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18583878 titled 'BATTERY MODULE
The battery module described in the patent application consists of stacked battery cells, each containing an electrode stack, an exterior package housing the electrode stack, and lead tabs connected to current collectors of the electrode stack. The lead tabs have extensions that protrude from the exterior package.
- The battery module includes fixation members that secure the battery cells by coming into contact with welding seals on the outer periphery of the exterior package in the stack direction. These fixation members are wider than the welding seals and are positioned closer to the electrode stack than the lead tabs in joint areas where the current collectors and lead tabs are joined.
- The fixation members play a crucial role in stabilizing the battery cells within the module, ensuring proper functioning and longevity of the battery system.
- This innovation enhances the structural integrity of battery modules, reducing the risk of damage or malfunction due to movement or external factors.
- By optimizing the positioning and design of the fixation members, the patent aims to improve the overall performance and reliability of battery modules in various applications.
- The unique configuration of the fixation members sets this patent apart from existing technologies, offering a novel solution to common challenges in battery module design and assembly.
Potential Applications: - Electric vehicles - Energy storage systems - Portable electronic devices
Problems Solved: - Enhanced stability and durability of battery modules - Improved electrical connectivity and performance - Minimized risks of damage or malfunction
Benefits: - Increased reliability of battery systems - Extended lifespan of battery modules - Enhanced safety features
Commercial Applications: The technology can be utilized in the automotive industry for electric vehicles, in renewable energy systems for efficient energy storage, and in consumer electronics for longer-lasting battery performance.
Questions about the technology: 1. How does the design of the fixation members contribute to the overall stability of the battery module? 2. What specific advantages does the positioning of the fixation members offer in terms of battery performance and longevity?
Original Abstract Submitted
A battery module includes stacked battery cells each including an electrode stack, an exterior package storing the electrode stack, and lead tabs to which current collectors of the electrode stack are connected, wherein the lead tabs each include an extension that extends from the exterior package, the battery module includes fixation members that are disposed to be in contact with welding seals provided on an outer periphery of the exterior package, in a stack direction, and fix the battery cells, the fixation members have a larger width than a width of the welding seals, and ends of the fixation members adjacent to the electrode stack are disposed closer to the electrode stack than ends of the lead tabs adjacent to the electrode stack, in joint areas in which the current collectors and the lead tabs are joined to each other.
