Fork-Shaped Electrode Tab Pad Plate for Li-Ion Battery Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Li-ion battery packaging requires a bracket to gather electrode tabs inward, which occupies space and limits battery capacity and performance, as it is necessary for insulation and safety.
Innovation Solution
A fork-shaped electrode tab pad plate with parallel fork feet and gaps is designed to accommodate electrode tabs, allowing them to be directed away from the battery housing, reducing space occupancy while ensuring safety and facilitating capacity improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a bracket is used to gather electrode tabs inward, then safety performance is improved, but battery capacity is reduced
Solution Approach 1:
The patent merges the functions of gathering electrode tabs and providing insulation into a single integrated pad plate structure. The pad plate combines the gathering function (previously requiring a separate bracket) with the insulation function, eliminating the need for additional space-consuming components while maintaining safety performance.
Solution Approach 2:
The pad plate extends in multiple dimensions with fork feet arranged in parallel, creating gaps between them to accommodate electrode tabs. This multi-dimensional arrangement allows the structure to gather tabs effectively while occupying minimal space, resolving the contradiction between safety requirements and capacity optimization.
2Reliability
If a bracket is used to gather electrode tabs, then insulation between electrode tabs and battery housing is guaranteed, but space for battery capacity improvement is reduced
Solution Approach 1:
The pad plate integrates the insulation function directly into its structure by positioning the fork feet to simultaneously gather electrode tabs and maintain insulation distance from the battery housing. This eliminates the need for a separate bracket that would occupy additional space.
Solution Approach 2:
The pad plate employs a thin, plate-like structure with parallel fork feet that creates gaps for tab accommodation. This thin-film approach provides effective insulation and gathering functions while minimizing volume occupancy, allowing more space for battery capacity improvement.
3Reliability
If a bracket with certain space is used for gathering electrode tabs, then safety is improved, but battery performance improvement is influenced
Solution Approach 1:
The pad plate combines gathering and insulation functions into one compact structure, eliminating the space requirements of traditional brackets. This integration maintains safety while removing constraints on battery performance improvement.
Solution Approach 2:
The pad plate is segmented into multiple parallel fork feet with gaps between them, allowing electrode tabs to be accommodated within these gaps. This segmentation provides effective gathering and insulation functions in a compact configuration that does not limit battery performance.

AI summary
The present application relates to an electrode tab pad plate, the electrode tab pad plate is of a fork shape, including a joint part and two first fork feet, the two first fork feet are arranged in parallel, and a first gap is provided between the two first fork feet, both the first fork feet are connected with the joint part. The electrode tab pad plate provided by the present application, through gathering the electrode tabs at inner sides of the electrode tab pad plate, so that the electrode tabs are gathered toward the direction away from the battery housing, so as to guarantee the safety performance of the Li-ion battery, since the space occupied by the electrode tab pad plate is small, which facilitates the improvement of the cell capacity, thereby improving the performance of the battery.
