ABSTRACT: Quallion LLC"s (Quallion) proposal responds to SBIR Solicitation No. AF103-065 entitled"Next-Generation Power Supply for Reentry Vehicles."Under this solicitation, Phase I calls for identifying"design concepts for highly reliable power supplies that meet both size and environmental requirements for longer shelf life prior to use [and to] evaluate the potential power supplies for viability and reliability in a high-stress, hostile environment in a compact package."In its response to this solicitation, Quallion proposes to leverage a former Phase I MDA SBIR effort to determine the feasibility of utilizing lithium-ion battery technology into a reserve type (decades of storage) battery application. The technology being investigated has shown potential to meet the following required characteristics outlined in the solicitation: - Minimized activation time, in the range of seconds - A stable voltage with ~35V as the nominal maximum - A minimum capacity of~700 to 1000 amp-sec - The ability to operate uninterrupted for tens of minutes Secondary characteristics that the battery should meet are as follows: - Improved energy density (peak specific power>10 kW/kg, specific energy>200 Whr/kg at the battery level) vs. current state of the art - Reduced volume (goal of 164 cm3) - A flexible form factor In this Phase I proposal, Quallion will further refine the process for the manufacturing of a reserve lithium-ion battery based on testing results to date; efforts will include the fabrication of proof of concept test cells. In this effort, Quallion will be primarily analyzing the mechanical design of the test cells and electrolyte salts used during forming and re-activation of the cell. BENEFIT: The initial target markets for this product are largely military in nature. A viable Lithium-ion reserve battery could potentially replace a number of existing legacy battery systems currently utilized in arming and fuzing systems, especially those that utilize missiles. Potential uses for Lithium-ion reserve batteries include: As a substitute for Ag Zn batteries in applications requiring high energy density batteries. As a substitute for primary Li batteries when safety concerns prohibit its use. As a substitute for thermal batteries when long run times>30 min make thermals large and potentially unsafe (high temperature). In addition to these immediate, existing markets for a Lithium-ion reserve battery, there are a number of new potential applications for which this battery could become an enabling technology. These applications would be characterized by performance requirements demanding long storage times, low cycle lives, and high temperature variability.

Quallion LLC is pleased to submit this proposal in response to the solicitation for"Modeling of Lithium-ion Cell Performance."This proposal focuses on the area of interest relating to"accelerated life testing for LEO because the processes that occur at the anode and cathode at high DoD"s (60+%) are poorly understood as to how they relate to low DoD"s (30% and lower)."Quallion has developed a reference electrode technology for acquiring detailed information on the life cycling of Li-ion cells. This technology coupled with the modeling capabilities of Dr. Ralph White and University of South Carolina can identify the key relationships of various DoD in cycling on Li-ion cell performance. The capability of predictive modeling of the effects of different DoDs could significantly reduce development time for introduction of lithium-ion batteries into MDA applications. Phase I will establish methods of incorporating reference electrode into cells, collect initial cycling data, and evaluate the methods of integrating data into the model. The modeling effort will evaluate two methods of predicting capacity fade. Phase II will develop long-term cycling data on test regimes and further develop the model capability for prediction of cycle life under different test regimes and DoDs.

Quallion LLC (Quallion) responds to SBIR solicitation No. A10-124 entitled Lithium Ion Batteries with Wide Operating Temperature Range. The objectives of this Phase I solicitation call for the development of [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. To achieve this objective in Phase I, Quallion will evaluate several cell electrolytes to optimize Quallions 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 6T form factor.

Quallion LLC"s (Quallion) proposal responds to SBIR Solicitation No. MDA10-034 entitled"Advanced Space Power Technologies". In our response, Quallion is targeting an electrode development for"beneficial materials development for space-quality lithium rechargeable cells that enable them to accommodate higher energy densities(>200Wh/kg at the battery level); higher charge and discharge rates with suitable voltage characteristics". Rate capability and energy density are determined by design configuration, and the materials in the battery. Even the inert components like current collectors and separators can contribute to losses in the available capacity and rate capability of the battery. Quallion proposes an electrode design that will reduce the overall internal resistance and increase the mechanical integrity of the electrodes. Phase I will identify an electrode design and process through physical, electrochemical analyses and cell tests. Phase II will further validate the process at a greater scale of manufacturing and large cell testing.
