2.2 Thermal Testing: High and Low Temperature Tolerance
Thermal testing evaluates how lithium-ion batteries perform under extreme temperature conditions. This testing process is essential for identifying risks like thermal runaway, which can lead to catastrophic failures.
Differential Scanning Calorimetry (DSC) and Modulated Differential Scanning Calorimetry (MDSC) are widely used to assess the thermal performance of battery electrolytes. DSC measures heat flow changes during phase transitions, while MDSC provides detailed insights into heat capacity and kinetic processes. These methods are particularly effective for understanding battery behavior at low temperatures.
For high-temperature tolerance, Fractional Thermal Runaway Calorimetry (FTRC) is a key method. Conducting multiple FTRC measurements helps predict heat output variability, ensuring accurate safety evaluations. This approach, combined with Accelerating Rate Calorimetry (ARC), creates quantitative safety maps for lithium-ion batteries, enhancing their design and safety.
Thermal testing is especially important for applications in Medical and Robotics, where batteries must operate reliably in diverse environments.
Note: Conducting comprehensive thermal testing minimizes the risk of thermal runaway, ensuring the safety and longevity of your battery systems.
2.3 Electrical Testing: Overcharge, Short Circuit, and Discharge Safety
Electrical testing focuses on evaluating the battery’s response to electrical stresses, such as overcharging, short circuits, and forced discharges. These tests ensure that lithium-ion batteries can handle electrical anomalies without compromising safety.
Test Type | Safety Requirements |
|---|---|
External Short Circuit Test | The battery must not ignite or rupture when subjected to external short circuits. |
Overcharge Test | The battery must not ignite or rupture when subjected to extended charging. |
Forced Discharge Test | The battery must not ignite or rupture when subjected to reverse polarity charging. |
Electrical testing is crucial for preventing thermal runaway caused by electrical faults. For instance, overcharging can lead to excessive heat generation, while short circuits may cause internal damage. By addressing these risks, you can enhance the safety performance of your lithium-ion batteries.
