Quallion LLC (Quallion) responds to SBIR solicitation No. A10-124 entitled âLithium Ion Batteries with Wide Operating Temperature Range.â The objectives of this Phase I solicitation call for the development of â[i]ncrease the operational temperature range of prismatic laminate lithium ion battery cells through electrolyte and materials improvements which allows transition of these batteries to Army ground vehicles without the overhead of specialized heating and cooling systems.â To achieve this objective in Phase I, Quallion will evaluate several cell electrolytes to optimize Quallionâs current low temperature electrolyte technology and increase its high temperature stability using its existing high power chemistry as a baseline. Quallion will evaluate several combinations of cell materials based on its extensive experience with a variety of cell materials capable of operating in the wide temperature range. When these studies are completed, Quallion will fabricate small test cells using the developed electrolyte and selected materials and conduct testing over a wide temperature range. Using the Phase I results, during Phase II, Quallion will produce large format cells integrated to a battery of the â6Tâ form factor.
