The growing market for electric vehicles (EVs) and plug-in hybrid vehicles (PHEVs) is driven by performance, vehicle range (higher energy, higher capacity), and battery pack life (cycle life). The near-term generations of these battery packs will be lithium-ion cell chemistries ranging from 5 to 50 kWh and the inherent safety issues and potential failure modes of these EV and PHEV batteries are of increasing concern. Unlike aqueous-based NiMH or NiCd batteries, most conventional lithium-ion cells contain organic solvent-based electrolyte that is highly flammable and use cathode materials that can undergo exothermic, autocatalytic thermal runaway. The failure of these cells can be catastrophic and are well documented in the consumer electronics industry. The Battery Abuse Testing Laboratory at Sandia National Laboratories is focused on determining failure mechanisms of lithium-ion cells, developing and evaluating abuse tolerant materials for cells, batteries and packs, and thermal characterization of lithium-ion cell materials.
