Current Collector Plate Flaps for Battery Height Variation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional secondary batteries face challenges in accommodating height variations of the electrode assembly due to tightly packed current collector plates, leading to issues with physical contact and assembly integrity.
Innovation Solution
The implementation of current collector plates with a frame member and flap members that accommodate height variations by allowing the flap members to adjust their position relative to the frame member, ensuring consistent contact with the electrode assembly and casing.

Engineering Contradiction Analysis
1Volume of moving object
If current collector plates are tightly packed to maintain compact battery structure, then battery size is reduced, but height variations of electrode assembly cause loss of physical contact and assembly integrity
Solution Approach 1:
The current collector plate incorporates a flexible flap member that can dynamically adjust its position to maintain contact with the electrode assembly despite height variations. The flap member transitions between different spatial positions (different planes) to accommodate the varying heights while maintaining assembly integrity.
Solution Approach 2:
The invention changes the spatial parameter of the current collector plate by positioning the flap member in a different plane from the frame member. This parameter change allows the flap to flex and adjust to electrode assembly height variations, maintaining reliable electrical connection without compromising assembly integrity.
2Ease of manufacture
If current collector plates are tightly packed to ensure compact design, then manufacturing simplicity is improved, but adaptability to electrode assembly height variations deteriorates
Solution Approach 1:
The current collector plate is segmented into a frame member and a separate flap member. This segmentation allows the flap to independently adjust to height variations while the frame maintains the overall structure. The divided structure provides both manufacturing simplicity and adaptability to electrode assembly variations.
Solution Approach 2:
The flap member is designed to be flexible and positioned in a different plane, enabling it to dynamically adapt to electrode assembly height variations. This dynamic capability is achieved without significantly complicating the manufacturing process, as the flap is still a single integrated component.
3Adaptability or versatility
If flap members are positioned in different planes to accommodate height variations, then adaptability is improved, but device complexity increases
Solution Approach 1:
By dividing the current collector plate into a frame member and a flap member, the invention achieves adaptability through a relatively simple segmented structure. The segmentation allows the flap to be positioned in a different plane for height accommodation without requiring a completely complex redesign of the entire current collector plate.

AI summary
A current collector plate includes a frame member having at least two arms. The at least two arms are arranged radially on the frame member to define two or more slots in the frame member. The current collector plate includes two or more flap members coupled to the inner periphery of the frame member and positioned in the two or more slots without being in contact with the at least two arms. Each flap member is in a plane different from the plane in which the frame member lies.
