Solution Overview
Problem
Electrochemical storage devices face challenges in efficiently dissipating heat at high power densities, which can lead to reduced service life due to thermal stresses and accelerated chemical reactions, especially in mobile and stationary applications requiring elevated power densities.
Innovation Solution
The system incorporates a heat dissipating device that enhances thermal contact with the electrochemical storage device, allowing for efficient heat dissipation through a receiving portion configured for direct contact, with a heat dissipating device receiving heat from the electrochemical storage device via a first surface and releasing it via a second surface, often with a larger surface area, and is designed to maintain a suitable operating temperature for ion conductivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electrochemical storage device operates at high power densities, then the electrical energy storage and delivery capability is improved, but thermal stress and chemical degradation increase reducing service life
Solution Approach 1:
The heat dissipating device is divided into multiple independent heat dissipating elements arranged around the electrochemical storage device. Each element independently dissipates heat from a specific region, allowing distributed thermal management that effectively handles high power density operations while maintaining device reliability through comprehensive cooling coverage
Solution Approach 2:
The heat dissipating device acts as an intermediary thermal management system between the electrochemical storage device and the environment. It receives heat from the storage device through thermal contact and transfers it to the environment, protecting the storage device from thermal stress and degradation while enabling high power density operation
2Temperature
If the spacing between the solid electrolyte and the wall is reduced to improve heat dissipation, then thermal management is improved, but mechanical stress on the solid electrolyte increases
Solution Approach 1:
The heat dissipating device segments the thermal management function from the structural containment function. The wall maintains adequate spacing for mechanical protection, while the separate heat dissipating elements provide thermal management through direct contact with the electrolyte, eliminating the need to compromise structural integrity for heat dissipation
Solution Approach 2:
The heat dissipating elements serve as intermediary components that directly contact the solid electrolyte for heat transfer, while the wall maintains its structural role with appropriate spacing. This intermediary approach allows efficient heat dissipation without compromising the mechanical protection of the electrolyte
3Temperature
If current density limits are imposed to reduce heat generation, then thermal load is reduced, but power delivery capability is limited
Solution Approach 1:
The heat dissipating device converts the harmful thermal byproduct of high current density operation into a manageable parameter. By efficiently removing heat during high power delivery, the system can operate at elevated current densities without thermal damage, effectively converting the thermal challenge into an acceptable operational parameter
Solution Approach 2:
The heat dissipating device provides continuous thermal management during operation, allowing the electrochemical storage device to continuously operate at high power densities without thermal accumulation. This continuous heat removal enables sustained high current density operation rather than intermittent operation with thermal limits
