Pre-Sodiated Hard Carbon Anode Materials for Sodium-Ion Battery Applications

This project focuses on the development of pre-sodiated hard carbon anodes for sodium-ion batteries (NIBs), offering a safer, cost-effective energy storage solution for defense applications. Sodium-ion batteries, unlike lithium-ion batteries (LIBs), are more thermally stable, can be manufactured from earth-abundant materials, and reduce dependence on foreign-sourced lithium and cobalt.áKey to this innovation is the use of pre-sodiated hard carbon, synthesized from renewable biomass sources such as agricultural waste, to improve the battery's initial efficiency and cycle life. The pre-sodiation technique mitigates irreversible capacity loss during the first cycle, a common drawback in traditional sodium-ion batteries. This results in greater energy retention, increased stability, and optimized performance across a wide temperature range from -20░C to 60░C.Defense applications include providing reliable, high-power bursts for directed energy systems and long-lasting, safe power for munitions. Sodium-ion batteries offer a superior alternative to current nickel-cadmium (NiCad) batteries in defense systems, reducing risks associated with thermal runaway and improving performance in extreme environments. Additionally, NIBs support strategic military requirements for domestically sourced materials, enhancing supply chain resilience.áDuring Phase I, the project will focus on synthesizing pre-sodiated hard carbon from renewable sources, characterizing its structural and electrochemical properties, and fabricating prototype coin cells. These cells will undergo performance testing to evaluate capacity, rate, and cycling stability, ensuring they meet defense requirements for high-power, long-cycle operation. The successful completion of Phase I will establish the feasibility of sodium-ion battery technology for defense energy storage, while Phase II will scale up production and demonstrate a complete NIB system.áThis innovation has dual-use potential, with applications extending to grid-attached storage, microgrids, and emergency backup power systems. The scalable, cost-effective production of these batteries aligns with both DoD needs and broader commercial markets, particularly in regions like California, which leads in energy storage projects.áFarad Powerĺs team, in collaboration with Columbia University and industry partners like Lockheed Martin, brings expertise in battery R&D, materials science, and defense-scale manufacturing, ensuring the successful transition of this technology from research to deployment.á
