Lithium ion battery cells and small battery packs (8 to 10 cells) are in wide consumer use today. Superior capacity has driven the demand for these batteries in electronic devices such as laptops, power tools, cameras, and cell phones. In the very near future, vehicle manufacturers will bring electric or hybrid electric vehicles to market using large lithium ion battery packs. The Research Foundation has initiated a project to review the literature on the hazards associated with lithium ion batteries in storage to provide baseline information for a hazard assessment and further research plan. A workshop on the topic will present findings midyear.
