Battery Cell Adapter Insulation Layout for Heat Conduction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heat generated during current flow through the adapter in a battery cell can cause insulation failure of the insulating member due to heat conduction, leading to potential short circuits.
Innovation Solution
Spacing a portion of the insulating member apart from the adapter reduces heat conduction, maintaining insulation performance and preventing insulation failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the insulating member is disposed close to the adapter to ensure insulation coverage, then insulation effectiveness is improved, but heat conduction from the adapter to the insulating member increases causing insulation performance failure
Solution Approach 1:
The insulating member is segmented into multiple portions (first insulating portion, second insulating portion, third insulating portion) that are spaced apart from the adapter at different locations. This segmentation allows each portion to provide localized insulation while maintaining distance from heat-generating areas, thus resolving the contradiction between ensuring insulation coverage and reducing heat conduction.
Solution Approach 2:
The insulating member acts as an intermediary element positioned between the adapter and the casing. By spacing portions of the insulating member away from the adapter, it mediates the thermal interaction while maintaining electrical insulation, preventing direct heat transfer to critical insulating areas.
2Temperature
If the insulating member is spaced apart from the adapter to reduce heat conduction, then heat transfer is reduced, but insulation coverage and effectiveness may be compromised
Solution Approach 1:
The insulating member is divided into multiple spaced-apart portions rather than a single continuous structure. This segmentation enables strategic positioning where insulation is most needed while maintaining gaps in heat-prone areas, achieving both thermal management and insulation effectiveness simultaneously.
Solution Approach 2:
Different portions of the insulating member are positioned at different locations with varying distances from the adapter based on local thermal and insulation requirements. Critical insulation areas maintain close proximity while heat-sensitive areas are spaced apart, creating locally optimized insulation quality throughout the structure.

AI summary
This disclosure pertains to the technical fields of batteries, and provides a battery cell, a battery, and an electric device. The electric device includes a battery, the battery includes a battery cell, and the battery cell includes a casing, an electrode assembly, an electrode terminal, an adapter, and an insulating member. The electrode assembly is disposed within the casing. The adapter is disposed within the casing and conductively connected to the electrode assembly and the electrode terminal. The insulating member is disposed within the casing and at least partially located between the adapter and the casing, and at least a portion of the insulating member is spaced apart from the adapter. Spacing at least the portion of the insulating member apart from the adapter can mitigate the problem that heat from the adapter being conducted to the insulating member causes failure of insulation performance of the insulating member.
