Application Note: Battery Safety
7 June 2011

In this application note, an Adiabatic Calorimeter is used to investigate lithium ion batteries (“18650” cells) in an adiabatic environment. Adiabatic temperature increase, temperature increase rate, pressure increase, pressure increase rate, and the temperature at which thermal decomposition begins are used to classify individual cells with regard to their potential risks and hazards, and for the comparison of cells made from different components.
