Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foamed metal electrode assemblies are prone to deformation due to tensile stress during processing, leading to reduced electrochemical performance and energy density.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If foamed metal is used as a substrate of an electrode plate, then the energy density is improved, but the electrode assembly is prone to deform under tensile stress during processing
Solution Approach 1:
The patent combines foamed metal substrate with filler material to create a composite electrode plate structure. The filler material forms continuous strands that bridge through the foamed metal, creating a hybrid material system that leverages the high energy density of the foamed metal while gaining the tensile strength and structural stability of the filler material. This composite approach resolves the contradiction by integrating two materials with complementary properties.
Solution Approach 2:
The patent applies filler material selectively within the foamed metal substrate, creating regions with different properties. The filler forms continuous strands at specific locations throughout the foamed metal structure, providing localized reinforcement where tensile stress occurs during processing. This allows the electrode plate to maintain high energy density in non-reinforced regions while gaining strength where needed.
2Strength
If the filler extends continuously from one edge to another edge of the foamed metal layer, then the tensile strength is increased, but the manufacturing complexity is increased
Solution Approach 1:
The patent utilizes the porous structure of the foamed metal substrate to accommodate and guide the filler material. The filler is deposited within the pore network of the foamed metal, allowing continuous strands to form naturally along the edges through the porous matrix. This approach simplifies manufacturing by leveraging the existing porous structure rather than requiring complex external molds or assembly steps to create continuous filler paths.
Solution Approach 2:
The manufacturing process allows the filler material to self-organize into continuous strands within the foamed metal substrate. The filler is introduced in a form that naturally conforms to the pore structure and edge geometry, enabling continuous reinforcement patterns to emerge during deposition without requiring complex external guidance or positioning mechanisms. The foamed metal structure itself serves as the template for filler arrangement.

AI summary
This application discloses an electrode plate, an electrode assembly, a battery cell, a battery, an electrical device, and an electrode plate manufacturing method and equipment. The electrode plate includes a foamed metal layer. A part of the foamed metal layer is a filled region. Pores of the filled region are filled with a filler. The filler extends continuously from one edge to another edge of the foamed metal layer, the two edges being arranged on two opposite sides along a first preset direction. The first preset direction is perpendicular to a thickness direction of the foamed metal layer. In the electrode plate disclosed in this application, a part of the foamed metal layer is configured as a filling region filled with a filler.
