We propose to develop a high energy density battery for military applications. These batteries will have an energy density of 1,130 Wh/l and a specific energy of 366 Wh/kg, which are much higher than those of rechargeable lithium batteries currently available in the market. They have extremely high cycle life (> 10,000 charge/discharge cycles), a wide operating temperature range, and a rapid rech ...

The objective of this proposal is to demonstrate the feasibility of developing advanced chemistries that allow batteries to operate safely at increased power density via improved discharge rate; higher energy density via improved battery packaging and improved coating of internal components(cathode and anode material); increased cycle life and depth-of-discharge via improved material stability; ex ...

The objective of this proposal is to demonstrate the feasibility of developing advanced battery chemistries that provide batteries that operate safely at increased power density via improved discharge rate, higher energy density through improved battery internal components/chemistry/cathode and anode material, increased cycle life and depth-of-discharge, exceptional durability when exposed to extr ...

This proposal is for an all solid state battery having a specific energy more than twice conventional lithium batteries. The rechargeable battery uses a lithium metal anode with ceramic electrolyte.  There are no liquids to leak out, catch fire, boil or increase in pressure.  There is no mechanism for lithium dendrite evolution during recharge.  Research under this proposal will also address un ...

Quallion currently manufactures hermitically sealed, prismatic 15Ah and 72Ah lithium-ion cells for the aerospace community. The cells are undergoing real-time life testing at varios government agencies, in which the 15Ah cell has demonstrated over 12,000 LEO cycles at a 60% depth of discharge (DOD). Under these conditions, Quallion expects the cell to perform over 50,000 cycles. Quallion’s resp ...

The US Air Force has a need for a corrosion-resistant lithium-ion battery terminal seal capable of twenty years of service life in a space environment. Key requirements include a terminal seal technology that provides electrical isolation, hermeticity, and is compatible with cell electrolyte. Ideally, the hermetic seal should have the design flexibility with respect to size, selectivity of materi ...

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 Techno ...

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 c ...

Recently developed gas/liquid (G/L) methodology, being used for cavitating flow problems, and extended for all-speed operability using preconditioning, will be used to analyze fuel jet atomization in high-speed military gas turbines. This methodology can capture G/L interfaces, and using multi-element unstructured numerics in conjunction with grid adaptation, will resolve G/L shear layer details n ...

The atomization of liquid fuels is a key process in gas turbine engines and augmentors, directly influencing combustion and thus engine performance. While adequate models exist for the secondary atomization, the crucial initial breakup is not well understood and predictive numerical simulation tools to analyze the process in detail do not exist. In this project, we propose to apply the recently d ...
