Electrode Traceability Monitoring Across Battery Manufacturing Processes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery manufacturing processes lack effective traceability and quality control, particularly in the electrode manufacturing stage, making it difficult to track the history and performance of battery cells across multiple processes and after they leave the manufacturing plant.
Innovation Solution
A battery monitoring system and method that connects coordinate data from various processes with inspection and measurement data using an electrode ID, allowing for the generation of monitoring data that tracks the position and quality of electrodes throughout the manufacturing process, improving traceability and reliability.

Engineering Contradiction Analysis
1Reliability
If coordinate data from multiple processes is collected and connected with inspection data, then traceability of battery components is improved, but device complexity increases
Solution Approach 1:
The system segments traceability data into distinct coordinate-related data sets for different processes (coating, rolling, slitting, winding) and connects them through process-specific coordinate systems. Each process maintains its own coordinate reference while being linkable to others, enabling comprehensive traceability without requiring a monolithic complex system.
Solution Approach 2:
The patent introduces coordinate data as an intermediary element that mediates between different manufacturing processes and inspection data. By using coordinate systems as the common language across processes, the system enables connection of disparate data sources without direct complex integration between all process elements.
2Manufacturing precision
If electrode position tracking is implemented across multiple processes, then manufacturing precision is improved, but measurement precision requirements increase
Solution Approach 1:
The system establishes coordinate reference points and coordinate systems in advance for each manufacturing process before actual electrode processing occurs. This preliminary setup of measurement frameworks enables subsequent position tracking without requiring high-precision measurements during every processing step, as the reference framework is pre-established.
Solution Approach 2:
Each manufacturing process uses its own local coordinate system optimized for that specific process's measurement needs and precision requirements. The coordinate data from different processes can have different precision characteristics appropriate to each process, rather than requiring uniform high precision across all processes.

AI summary
A battery monitoring system includes at least one memory configured to store a first coordinate-related data set in which coordinate data indicating a position of an electrode moved in each of a plurality of processes is connected with inspection data and/or measurement data of the electrode obtained in the plurality of processes, and an identification data set including an electrode identifier (ID) identifying the electrode. The battery monitoring system further includes at least one processor configured to connect the electrode ID with the coordinate data of the first coordinate-related data set corresponding to the electrode ID, and send monitoring data for the electrode, based on data about the connection of the electrode ID with the coordinate data.
