Fundamental Safety Studies of Li-ion and Na-ion Batteries

Accelerating Rate Calorimetry (ARC) is used as the major method to study the reactions between charged electrode materials and electrolytes at elevated temperature1,2. This is a significant step to leverage the safety performance of novel electrode or electrolyte materials before scaling up.
