SYSTEMS AND METHODS FOR BATTERY MANUFACTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240222813 titled 'SYSTEMS AND METHODS FOR BATTERY MANUFACTURE

Simplified Explanation: The patent application describes a method of manufacturing a battery cell using a laser welding device to pre-weld a first member with a current collector before fully welding them together.

Laser welding device used for pre-welding and welding battery cell components
First beam emitted for pre-welding a first member with a current collector
Second beam emitted for fully welding the first member with the current collector
First beam duration is shorter than the second beam duration

Potential Applications: This technology can be applied in the manufacturing of various types of battery cells, including those used in electric vehicles, consumer electronics, and renewable energy storage systems.

Problems Solved: This method addresses the need for efficient and precise welding of battery cell components, ensuring a strong and reliable connection between the current collector and other parts of the cell.

Benefits: - Improved manufacturing efficiency - Enhanced battery cell performance and reliability - Cost-effective production process

Commercial Applications: The technology can be utilized by battery cell manufacturers looking to streamline their production processes and enhance the quality of their products. It can also benefit industries reliant on battery technology, such as electric vehicle manufacturers and energy storage companies.

Questions about Battery Cell Manufacturing: 1. How does the use of a laser welding device improve the efficiency of battery cell manufacturing? 2. What are the potential cost savings associated with implementing this method in battery cell production?

Original Abstract Submitted

a method of manufacturing a battery cell is disclosed. the method can include emitting, by a laser welding device for a first duration, a first beam to pre-weld a first member with a current collector. the method can further include emitting, by the laser welding device for a second duration, a second beam to weld the first member with the current collector. the method can include the first duration of the first beam being less than the second duration of the second beam.
