Bent Insulator Battery Electrode Bonding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face challenges in maintaining strong bonding between components, leading to potential displacement or separation during manufacturing and usage, which can result in short circuits and reduced reliability.
Innovation Solution
The battery design incorporates a first insulator with bent portions that position electrode and counter-electrode layers facing each other, enhancing bonding strength and preventing contact with external members, thus securing the positional relationship and reducing the risk of short circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If battery components are assembled without sufficient bonding strength, then assembly is simpler, but components may displace or separate during manufacturing and usage
Solution Approach 1:
The insulator is integrated with the electrolyte to form a unified component structure. The insulator includes a first electrolyte portion, a second electrolyte portion, and a bent portion that connects them, creating a single assembled unit that simultaneously provides insulation and electrolyte functions while maintaining strong bonding between components.
Solution Approach 2:
The insulator incorporates a bent portion with a specific curved geometry that allows the first and second electrolyte portions to be positioned facing each other while maintaining intimate contact. This curved configuration enhances bonding strength and prevents displacement of components during battery operation.
2Reliability
If battery components are tightly bonded to prevent displacement, then reliability improves, but manufacturing precision requirements increase
Solution Approach 1:
The insulator is pre-formed with the bent portion configuration before battery assembly. This preliminary structuring ensures that when the first and second electrolyte portions are positioned, they automatically achieve the correct facing arrangement and intimate contact, reducing the precision requirements during final assembly while ensuring reliable component bonding.
3Strength
If electrode layers are positioned facing each other with bent insulator, then bonding strength increases, but device complexity increases
Solution Approach 1:
The insulator serves multiple functions simultaneously: it provides electrical insulation between electrode layers, contains and positions the electrolyte portions, creates the bent configuration for component bonding, and prevents contact with external members. This multi-functionality reduces the need for separate components, offsetting the structural complexity with functional integration.

AI summary
A battery includes a first insulator, a first electrode layer, and a first counter-electrode layer. The first counter-electrode layer is a counter electrode for the first electrode layer. The first insulator includes a first electrolyte portion, a second electrolyte portion, and a first bent portion. The first bent portion is positioned between the first electrolyte portion and the second electrolyte portion. The first electrode layer is disposed in contact with the first electrolyte portion. The first counter-electrode layer is disposed in contact with the second electrolyte portion. The first insulator is bent at the first bent portion, and thereby the first electrode layer and the first counter-electrode layer are positioned facing each other.
