PHYSICAL SCIENCES INC. — Department of Defense STTR Phase I: N18A-T008

Description

Physical Sciences Inc. (PSI) will develop novel feedstocks for 3D printing of lithium-ion batteries using existing additive manufacturing technologies. Lithium-ion batteries simultaneously offering high energy and power density energy will be demonstrated using the novel feedstock materials. PSI’s proprietary HA coating technology will be utilized in the feedstock formulations to maximize active material content and to unlock solvent-free 3D printing of high performance electrodes. During the Phase I program, PSI will formulate solid anode, cathode and separator processing streams that can act as feedstocks for additive manufacturing technologies. PSI will collaborate with the University of South Carolina to collect structural imaging data of the 3D printed lithium-ion cells during electrochemical cycling. During the Phase I option, pouch cells will be constructed to demonstrate the scalability of the approach and the unique geometries available through additive manufacturing. Successful completion of these efforts will demonstrate the readiness of the technology for further scale-up and demonstrations in Phase II.
