Battery Calorimetry Laboratory

One of four “workhorse” accelerating rate calorimeters. These systems run continuously to keep up with customer needs. Lithium-ion battery technology offers great benefits in portable power, but an essential challenge is to ensure operational safety. Current lithium-ion technologies are prone to thermal runaway reactions. In order for electric vehicle (EV) and hybrid [...]

Characterization and Failure Analysis

Sandia tests batteries to failure to determine the safety design margins. Publicity of Sandia tests often is focused on the strong reactions that occur when lithium-ion batteries release energy under abuse conditions without consideration of the significant improvements that have been realized in recent years. Our abuse testing provides a wealth of data [...]
