Advanced Electrodes and Electrolytes for Improved Energy Density and Safety Lithium-Ion Batteries

Rechargeable batteries with improved safety and significantly higher energy densities are needed to reduce the weight carried by soldiers, provide improved safety, provide power for extended duration missions, and enable constant and reliable soldier communication. Current state-of-the-art secondary lithium-ion batteries do not provide the energy density and safety needed for extended duration solider missions. The performance and safety of present lithium-ion batteries is limited by the current electrodes and electrolytes used (e.g. carbon anode, lithium cobalt oxide cathode, and organic solvent-salt electrolyte), and new materials are needed. Lynntech proposes to develop advanced rechargeable lithium-ion batteries based on advanced anode, cathode, and electrolyte components, resulting in batteries with higher energy densities and improved safety compared with current cells. During the Phase I project, Lynntech will develop advanced electrodes and electrolytes for the secondary Li-ion batteries, and evaluate the capacity, energy density, and cycle life of the components in half and full cells. During Phase II, Lynntech will optimize the cell components and evaluate the cycle life, temperature range, and rate capabilities of prototype cells to meet target specifications. The advanced rechargeable Li-ion batteries cells can provide improved safety, cost-effective, high energy density batteries for extend duration solider missions and other applications.
