Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If lithium-ion batteries with sulfur dioxide-based electrolytes are used to achieve higher energy and voltage, then energy density and power output are improved, but the risk of electrolyte leakage and environmental contamination increases in case of defects
Solution Approach 1:
A safety device is introduced as an intermediary component between the battery cells and the external environment. This device includes a cleaning unit with liquid additive that neutralizes gaseous electrolyte components, preventing direct contact between leaked electrolyte and the surroundings. The safety device acts as a protective barrier that allows high-energy sulfur dioxide-based electrolytes to be used while mitigating their harmful effects upon leakage.
2Stability of the object's composition
If sulfur dioxide-based electrolyte is used to ensure stable operation at high voltages, then voltage window stability is improved, but gaseous electrolyte components can contaminate the surroundings upon cell defect
Solution Approach 1:
The safety device contains a cleaning unit that converts the harmful gaseous electrolyte components into beneficial neutralized substances. The liquid additive chemically reacts with gaseous sulfur dioxide and other electrolyte components, transforming them from harmful contaminants into harmless or less harmful substances that can be safely vented or contained, thus converting the hazard into a controlled process.
3Power
If battery bank operates with high-voltage lithium-ion cells for electric drive applications, then power output and efficiency are improved, but mechanical, electrical, or thermal defects can cause electrolyte release into the environment
Solution Approach 1:
The safety device is pre-installed and pre-configured within the battery bank system before any defects occur. The cleaning unit is filled with liquid additive and positioned to immediately intercept and neutralize gaseous electrolyte components upon release. This prior preparation ensures that when mechanical, electrical, or thermal defects occur during high-power operation, the protective mechanism is already in place to prevent environmental contamination.
