Light-weight, Flexible, Wearable, Fast Charging, Safer Solid-State Lithium-ion Battery Prototype
Abstract
Purdue Universitys safe, flexible Solid State Battery (SSB) that has a long cycle life and enhanced thermal stability is proposed t,o meet and exceed mission requirements for fast charge-discharge batteries that can be fitted to meet different size/dimensions as r,equired for different defense applications. Proposed project, named NAVs Flex SSB, will deliver fully functional and safe >300 Wh K,g-1 energy density batteries that can achieve >80% of its initial capacity after 1000 charge-discharge cycles at a 1C rate. This typ,e of fast charge-discharge usage continually over a long period of time is often experienced by Navy and Marine Corps missions, wher,e technology must be able to meet strenous demands of time constraints and with the added benefit of being flexible and safe this wi,ll allow the proposed batteries to be form fitted to their specific applications while removing the risk of battery explosions/fires,. --These mission requirements will be accomplished by the advancement of critical cell components: a high ionic conductivity (2.4,10-4S cm-1 at room-temperature) and high thermal stability (330C) innovative inorganic-organic solid state electrolyte (SSE) [LLZTO,-polyvinyl difluoride (PVDF)-LiCFNOS (LiTFSI)] and perylene-3,4,9,10-tetracarboxylic dianhydride (PTCDA) as the flexible ultralo,ng lifespan (>1000 cyles) organic cathode will be utilized to create a functioning SSB. Proposed NAVsFlexSSB project will meet four, main objectives in the two-year period: 1) Incoporate Purdues latest ground-breaking high voltage organic cathode and ~20 m scala,ble, enhanced ionic conductivity, flexible solid-sate electrolytes tailoring and its implementation further minimizing the interfaci,al resistance in coin cells, 2) Fabricate SSB pouch cells to demonstrate cell capacities of >500 mAh at long cycle life with the two, novel cell componenets (composite SSE & organic cathode), 3) Collaborate with NSWC Crane to guide devolpment of a prototype for tes,ting in autonoumous unmanned vehicles (AUVs) like drones and submarines by leveraging their expertise in lithium battery safety eval,uation in prototype testing, thermal energy yield under normal operation and thermal runaway, and demonstration in ANTX and ATD even,ts,4) Prepare the next generation workforce for Navy, DoD, DoE and NASA, by educating and training students from ROTC, active and re,tired military (veterans, USMC Cadets, USAFA Cadets, USNA Midshipmen), and providing internship opportunities at NSWC Crane, Navy, D,oD, DoE, NASA and other government agencies. This objective will be achieved through close collaboration and continual refinement of, our design between Purdue and NSWC Crane. Approved for Public Release
