Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for forming three-dimensional electrode structures using digital twin technology fail to accurately match the actual electrode type and volume characteristics, leading to low systematicity in verification and structure formation.
Innovation Solution
A method involving setting a sample structure volume, forming an initial electrode structure, and verifying it by adjusting design parameters such as material type, content, shape, and mechanical properties, with a focus on reducing volume to achieve a 10% error ratio or less in structural parameters, and correcting angles based on error ratios to achieve a ±5% match with actual electrodes.

Engineering Contradiction Analysis
1Manufacturing precision
If three-dimensional formation technology and three-dimensional reconstruction technology are combined to form an electrode structure, then a three-dimensional electrode structure can be formed, but the matching degree to the actual electrode is lowered and the structure reflecting the volume characteristics of the electrode cannot be formed
Solution Approach 1:
The patent creates a digital twin (virtual copy) of the actual electrode structure through three-dimensional reconstruction technology. This digital copy accurately reflects the volume characteristics and structural parameters of the real electrode, enabling precise modeling without requiring complex physical formation processes. The digital twin serves as a faithful reproduction that maintains all essential geometric and structural properties of the original electrode.
Solution Approach 2:
The patent transforms physical electrode parameters (volume, shape, structural characteristics) into digital model parameters through systematic measurement and reconstruction. By changing the representation from physical to digital domain, the method preserves all volume characteristics while simplifying the formation process. The digital model allows direct manipulation and verification of structural parameters without physical constraints.
2Ease of manufacture
If the electrode structure is formed in the same manner regardless of the type of electrode, then the formation process is simplified, but the matching degree to the actual electrode is lowered
Solution Approach 1:
The patent develops a universal digital twin formation methodology that can be applied to any electrode type (lithium-ion, solid-state, flow batteries, etc.). The same three-dimensional reconstruction and digital modeling process works across different electrode technologies, providing both simplicity and accuracy. The method adapts to various electrode geometries and materials through parameter customization rather than process modification.
3Productivity
If the volume of the electrode structure is reduced, then the computational efficiency is improved, but the structural parameters such as tortuosity and specific surface area become inaccurate
Solution Approach 1:
The patent applies partial action by creating a digital twin that includes only the essential structural parameters needed for analysis (tortuosity, specific surface area, volume ratio) rather than attempting to model every detail of the electrode. This selective modeling approach maintains accuracy for the critical parameters while reducing overall computational complexity. The digital twin captures sufficient detail to preserve structural parameter accuracy without requiring excessive computational resources.
