Two laboratory facilities are to be operated under this effort in Building #205 of the Chemical Sciences and Engineering Division (CSE), a laboratory-scale battery cell fabrication facility and a battery cell post test analysis facility. The focus of both facilities will be advanced lithium-ion battery technologies. These technologies typically contain positive electrodes coated on aluminum foil comprised of a lithiated transition metal (for example nickel, manganese, or cobalt) oxide active material powder and high surface area carbon additive, held together by a polymer binder. The negative electrode is typically a carbon active material powder coated on copper foil with polymer binder. A porous polymer separator (such as polyethylene) is used to separate the electrodes. The cell layers are either wound or stacked and placed into a metal container or foil/polymer pouch. Current collector tabs are attached to the foils, an organic solvent electrolyte (for example lithium hexafluorophosphate in a mixture of organic carbonates) is added, and the cell is sealed.
