Sandians as Guest Editors of Modeling & Simulation in Materials Science and Engineering Focus Section

Inputs and outputs to the Sandia battery-abuse modeling program, focusing on bridging the gap between atomistic and cell-level simulations. Each link in the chain builds on the results from the previous, finer-detail stage to ultimately deliver an accurate predictive capability to assess new battery chemistries before building prototypes. Many vital needs in worldwide [...]

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 [...]

Sandia Researchers Find Energy Storage “Solutions” in MetILs

A flow battery is a rechargeable energy storage device that pumps a solution of charged metals dissolved in an electrolyte through a membrane to convert chemical energy into electricity. Flow batteries can be rapidly "recharged" by replacing the electrolyte liquid while simultaneously recovering the spent material for external recharging. Researchers at Sandia National [...]
