The Li sulfur battery system also offers benefits to other national needs. This includes national defense systems such as unmanned aerial vehicles, unmanned underwater vehicles (AUV's), and soldier portable power systems. Benefits to the terrestrial energy sector include: all-electric and hybrid cars, grid-scale energy storage systems, smart grid, and remote, off-grid power systems (crewed vehicles and habitats). Lithium sulfur battery has created an interest among industry participants for automotive applications because of its inherent features. A lithium sulfur battery is likely to provide the right solution for the issues that are challenging the demand for lithium-ion batteries in HEVs and EVs.","description":"Energy storage devices in many aerospace applications are facing unique challenges. Most of such applications, including remote surveillance, satellites, reusable launch vehicles, etc. depend on high-performance, highly specialized batteries. In Phase I, STI prepared and tested several sulfur-carbon nanocomposites of different formulations to identify parameters that affect composite performance characteristics. High efficient electrolyte solvent was prepared and demonstrated with high Coulombic efficiency and good cycling performance. During the Phase II, the composite's composition will be optimized further. Electrolyte solvent will be further optimized to increase the purity and Li ion conductivity. In parallel, cells with 500 mAh capacity will be designed and prototype batteries will be fabricated and

A lithium sulfur battery is likely to provide the right solution for the issues that are challenging the demand for lithium-ion batteries in HEVs and EVs. Lithium sulphur batteries are likely to be available at a much lower price and with higher energy density compared to lithium-ion batteries. Lithium sulphur batteries offer almost three times the energy density as the current lithium-ion batteries. This allows these batteries to run more than 300 miles on a single charge in a passenger electric vehicle. Sulphur is abundantly available, so that reduces the cost of these batteries, thereby making it much more affordable than lithium-ion batteries. These features make lithium sulphur batteries a better choice over lithium-ion batteries. Lithium sulfur battery system also promises to transform the energy storage and distribution fields. This technology, in the distributed energy storage form, reduces greenhouse emissions by serving as a gateway technology to the widespread use of alternative and more importantly intermittent energy sources, namely wind and solar.","description":"Energy storage devices in many aerospace applications are facing unique challenges. Most of such applications, including remote surveillance, satellites, reusable launch vehicles, etc. depend on high-performance, highly specialized batteries. NASA desires high specific energy batteries that are safe for human exploration missions. Since none exist today, they must be developed. Storagenergy Technologies Inc. and its team members propose to develop a novel core-shell structured sulfur-carbon nanocomposite and novel electrolyte systems for high performance rechargeable lithium-sulfur batteries. In Phase I, the composite materials will be synthesized and characterized. The composite's electrochemical performance along with novel electrolyte systems will be evaluated in full cells. Cells with with a minimum capacity of at least 200 mAh will be fabricated and evaluated. During the Phase II, the composite's composition will be optimized further, its performance in cells with 1Ah will be evaluated, and a low-cost large-scale material production process will be developed.","startYear":2013,"startMonth":5,"endYear":2013,"endMonth":11,"statusDescription":"Completed","website":"","program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
