NICOP - Investigate the possibility of development of Large-sized Organic Radical Battery
Abstract
Investigate the possibility of development of Large-sized Organic Radical Battery:Technical descriptions: Organic Radical Battery (ORB) can achieve both high-power density and high-energy density (i.e., currently ~50 Wh/L, 7 kW/L), which is either comparable or better than Electric double-layer capacitor (EDLC) and lithium-ion rechargeable battery (LiB). At the same time, ORB has advantages over EDLC and LiB in terms of the flexible, thin and lightweight material, rapid charging, no thermal runaway and swell-up overcharge, and being free of harmful or heavy metals. NEC aims to conduct basic and applied research tasks necessary in order to scale-up the ORB so that it can become suitable for applications that require higher power output (e.g., 18(x) ~ 18(y) ~ 1.5(x) ~ 8 stacks, 110 Wh and power 20 kW). The technical challenges that need to be addressed in order to achieve the goal are: (i) to develop the optimum Li-doping method that improves the power output of the carbon anode while controlling the manufacturing cost; (ii) to optimize the electrode fabrication process in order to maximize the material strength and to prevent defective failure; and (iii) to optimize the electrolyte composition to improve temperature properties. These challenges will be addressed through bench-top experiments, prototype fabrication, and tests for both power output and material physical properties. b. Naval Relevance: In terms of the power output characteristics, the direct competitor for the ORB may be the A123 AHR26700 Li ion power cell used in F1 racing and other high power applications. However, ORB has the potential to become advantageous over the existing technology due to its flexibility, fast charging, and possible lower cost. The possible high-power applications for ORB include ground vehicle-based directed energy weapons. In addition, the flexible and light weight nature of the ORB may be developed into conformal batteries for individual Marines. c. Coordination: The proposal has a buy-in from ONR30 PO Billy Short. d. Desired Outcome: If the project is successful, I will help potential NRE customers connect with the ORB engineers at NEC for testing and integration into Naval systems in need of Novel high- or light/flexible-power sources.
