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's intends to develop an all-solid 600 Wh/kg, flexible form-factor lithium rechargeable energy device for advanced space power applications. Quallion's approach is to achieve greater than 600 Wh/kg combines three key proprietary developments: (1) a recently developed electrolyte, (2) a lithium surface treatment technology and (3) a high energy density cathode.The all-solid high-energy density battery can meet NASA mission requirements. The system has a non-flammable electrolyte, making it safer than current state-of-the-art, but with greater energy and tolerance to abuse, making it ideal for manned missions. NASA would be able to deploy this battery without any risk of fire or catastrophe.

Quallion LLC proposes to continue development of its double-layer electrode technology for lithium ion batteries. The double-layer electrode technology increases adhesion of active materials to improve mechanical strength and the increased surface area increases conductivity. Quallion will refine its electrode design based on lessons learned in Phase I by adjusting the composition of coating materials and the electrode coating process, and incorporating the double-layer electrode into commercial satellite cell designs. Quallion will build prototype cells and perform testing to validate their performance and to generate data for further analysis.

Quallion LLC proposes to continue development of its reference electrode technology into a commercial scale prototype and partner with the University of South Carolina to develop a life prediction model for cells cycled at high depths of discharge. In Phase II, Quallion will refine its reference electrode design based on lessons learned in Phase I, incorporate a reference electrode into commercial satellite cell designs, and build prototype cells with reference electrode for testing to validate their performance and to generate data for the modeling effort. Quallion will also build cells using the current 72Ah commercial cell design utilizing the new Gen2 chemistry and perform life testing on these cells at 60% DOD. The modeling effort will evaluate two methods of predicting capacity fade, one based on operational capacity checks and the other on on-line monitoring of parameters during cycling. Parameters will include data gathered by the reference electrode. 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 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"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.

Quallion LLC was awarded contract No. W56HZV-11-C-0047 under Army topic No. A10-139 entitled"Lithium Air Rechargeable Battery."The solicitation calls for a lithium air battery with a much higher energy density and longer duration energy storage system to replace lead acid or lithium ion batteries in non-primary power systems and silent watch applications. To achieve the objective in Phase II, Quallion proposes two major changes to the lithium-air system to increase energy density and cycle stability. These developments will reduce the overall weight of the cell by 50% and stabilize the cell performance increasing energy density toward 1000 Wh/kg and cycle life toward 200 cycles. In addition, the proposed technology will provide potentially limited self-discharge, good charge/discharge efficiencies, low temperature performance, and a long calendar life of lithium batteries.
