NOHMs Technologies proposes to develop a novel ionic liquid electrolyte formulation developed for the Lithium-Sulfur chemistry that can protect the lithium metal and has demonstrated superior performance and safety characteristics with the potential to offer 600 Wh/kg on the cell level. For this NASA Phase I project, NOHMs Technologies will optimize our proprietary ionic liquid electrolyte and demonstrate how the electrolyte provides safe, non-flammable high-energy performance and provides Li-metal protection. NOHMs will provide full cell data and analysis to demonstrate the feasibility of our system to meet NASA's 'Far Term Mission' specific energy and energy density goals. The battery technology under development by NOHMs is capable of delivering batteries with specific energies that are three times higher than today's state of the art Li-ion battery systems. For NASA missions, this can be translated into increased operational range, functionality, or payload capabilities and significantly reduced operational cost. NASA applications.

Project Summary NOHMs Technologies proposes to develop a novel Lithium-Sulfur (Li-S) battery system as a reliable emergency power source for assistive medical equipment. NOHMs Li-S battery can increase the energy delivery time in a power outage from 2 hours to 24 hours or more, while yielding a significant reduction in weight, size, and cost compared to existing emergency power supply systems. Li-S offers one of the highest theoretical energy densities (2.3 kWh/kg) among rechargeable batteries. The proposedtechnology is based on innovative sulfur-infused carbon composite cathode materials and safer electrolytes. These materials overcome the poor cycle life problems that have limited commercialization of lithium-sulfur batteries by encapsulating sulfur in nanometer-sized mesoporous carbon capsules (S C) and with novel electrolytes that overcome lithium batteries safety issues associated with the metallic lithium anode. The Phase I project focuses on the development and design of a high energy Li-S battery su

This proposed Small Business Innovation Research Phase II project will develop a novel nano- scale process for synthesizing sulfur-infused carbon composite cathode materials to produce high- energy density lithium-sulfur (Li-S) secondary batteries with a high rate of charge/discharge and extraordinarily long cycle life. Lithium-sulfur batteries with a long cycle-life are a potentially disruptive technology in the $11-$13 billion lithium-ion battery market because of their three to fourfold energy density advantage over existing chemistry platforms. The technical objectives of this Phase II proposal include the optimization of the electrochemical performance of Sulfur-Carbon composite materials as well developing and implementing scalable unit processes for materials and cell manufacturing. This project will assemble and test pouch cells in sufficient quantities to demonstrate >600Wh/kg operation for 700 cycles with minimal product-to-product variability and reliable performance. Success in Phase II will provide an important pathway to receiving institutional venture funding and building joint-development partnerships to successfully transition NOHMs unique Li-S battery technology to commercial markets.
The broader impact/commercial potential of this project is significant. Secondary lithium-sulfur batteries employing sulfur as the cathode and metallic lithium as the anode offers the highest energy storage potential of any two solid elements. They offer more than twice the specific energy of currently deployed lithium ion battery technology with half the weight. Li-ion batteries currently have a $14 billion market and are expected to reach $44 billion by 2020. They account for close to 75% of all secondary (rechargeable) batteries used in portable electronics. If the potential of these batteries can be harnessed and scaled economically, they are expected to disrupt current lithium ion cell technology because of their higher energy density and the low cost and wide-spread availability of sulfur. Li-S batteries could transform the mobile device market, the electric vehicle market, and energy storage market, enabling greater efficiency and power in all those sectors.

NOHMs propose to develop, demonstrate, and deliver high energy, lightweight, safe lithium sulfur (Li-S) batteries for use in space applications. During the Phase II project, NOHMs Technologies pursue approaches for enhancing energy density, safety, and manufacturability of larger-format pouch cells based on the most promising electrode and electrolyte compositions identified in Phase 1. We will demonstrate benchmarked improvements in performance and safety metrics in 2 to 4 Ah cells that will be tested and integrated into space applications such as space suits. NOHMs will provide full cells to demonstrate the feasibility of our system to meet NASA's 'Far Term Mission' specific energy and energy density goals. The battery technology under development by NOHMs is capable of delivering batteries with specific energies that are two times higher than today's state of the art Li-ion battery systems.
