Scalable Manufacturing of Safer, Energy Dense Li-ion Batteries for Critical Temperature Defense Application
Abstract
Purdue Universitys multifunctional lithium-ion battery that is safe and exhibits high energy density and thermal stability is proposed to meet and exceed mission requirements under high and low temperature environments experienced by defense applications. Proposed project, named NAVSaFBat, will deliver fully functional and safe 500mAh rechargeable batteries that have beendemonstrated in extreme operating temperatures (40C to 60C) often experienced by Navy and Marine Corps missions by advancing several critical cell components: tailored polypropylene separator, anode made of conductive carbon cloth/3D-designed porous-Cu foam supported with ultrathin lithium, high capacity cathode, and fluorinated solvent based electrolyte that exhibitsprolonged cycle stability and ultra-stable Coulombic efficiency. Proposed NAVSaFBat project will meet four main objectives in the two-year period: 1) Incorporate two of Purdues latest ground-breaking proof-of-concept innovations in advanced separators with several meters long tri-layer separator development with implementation of modified electrolytes, 2) Fabrication and testing of lithium metal battery pouch cells to demonstrate charging and discharge capacities of>500 mAh at high and low temperatures with NMC cathodes, 3) Purdue university will collaborate with Naval Surface Warfare Center, Crane Division (NSWC Crane) on thermal safety studies on an advanced battery prototype and demonstration in a defense technology development event (ANTX, ACTD, etc.) or at independent site with a RC vehicle, and 4) Prepare the next generation Navy, DoD, DoE and NASA workforce by educating and training students from ROTC,active and retired military (veterans, USMC Cadets, USAFA Cadets, USNA Midshipmen) and providing internship opportunities. This objective will be achieved through close collaboration and continual refinement of our design between Purdue and NSWC Crane.
