Prismatic Battery Folded Edge for Heat Dissipation and Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional batteries have a small heat exchange area due to their thin flange design, which hampers heat dissipation and structural strength, making them inconvenient to configure into a box.
Innovation Solution
A prismatic battery design with a folded edge on at least one edge of a first side, increasing the heat exchange area and structural strength, allowing for improved heat dissipation and easier configuration into a battery device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a thin flange is used on the battery, then the manufacturing cost is reduced, but the heat exchange area is small and structural strength is poor
Solution Approach 1:
The patent transforms the traditional planar flange into a three-dimensional folded structure by adding folding lines and creases. This dimensional transformation allows the flat flange material to be folded into a立体 structure that protrudes from the battery surface, significantly increasing the contact area with the heat dissipation plate while maintaining the same material usage and manufacturing process.
Solution Approach 2:
The flange is divided into multiple regions by introducing folding lines and creases. These segmentation lines create distinct folded portions that can be arranged in various patterns (such as radial, grid, or wave patterns), allowing the flange to achieve complex three-dimensional shapes that maximize heat exchange area while maintaining structural integrity.

3Strength
If a folded edge structure is added to the battery flange, then the heat exchange area and structural strength are improved, but the device complexity increases
Solution Approach 1:
The folded flange structure is designed to be self-forming through the battery's existing manufacturing process. The folding lines and creases are integrated into the diaphragm molding step, allowing the flange to automatically fold into its three-dimensional shape during normal production without requiring additional assembly steps, tools, or operations.
Solution Approach 2:
The patent combines the flange formation process with the existing diaphragm molding process. The folding lines and creases are incorporated into the single-layer or multi-layer film structure during the molding step, merging the flange creation with the battery encapsulation process and eliminating the need for separate flange manufacturing and assembly operations.

AI summary
The disclosure relates to the technical field of batteries, and particularly to a battery and a battery device. The battery has a prismatic structure, a top surface, a bottom surface, two first sides, and two second sides. The two first sides are spaced apart along a first direction and each perpendicular to the first direction. The two second sides are spaced apart along a second direction and each perpendicular to the second direction. The first direction is perpendicular to the second direction. An area of the first side is greater than an area of the second side, a folded edge is disposed on at least one edge of one of the first sides, and the folded edge extends in the first direction.
