The objective of this proposal is to demonstrate the feasibility of developing advanced chemistries that allow batteries to operate safely at increased power density via improved discharge rate; higher energy density via improved battery packaging and improved coating of internal components(cathode and anode material); increased cycle life and depth-of-discharge via improved material stability; exceptional durability when exposed to extremes in temperature via an improved binder system; and a decrease or total elimination of the calendar-life limitations of lithium ion batteries (Li-ion) through the improved stability and improved binder system. YTP has proposed to develop advanced Li-ion batteries for space-based application by improving the battery materials, electrode processing and the cell chemistries. During Phase I of this program, YTP has successfully demonstrated the Phase I proof of concept of this proposal by focusing on developing novel electrode manufacturing technology and surface modified electrode materials. Phase II of the program will incorporate the Phosphate coated materials, cell chemistries and new processes developed in Phase I to fabricate prototype cells for test under LEO-type test profiles. Power output and energy capacity will be scaled up to levels appropriate for integration into battery packs to demonstrate the path forward for subsystem-level performance. BENEFIT: The target application for this surface modified cathode based Li ion battery is in Air Force applications where safety, longer cycle life, high energy density and power densities are required. This new technology will have superior performance even at low and high temperatures due to robust electrode coating method and surface modification of the electrode materials.
