Description
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
