Li-ion Battery Safety by Prevention, Detection, and Control
Abstract
Funds are provided to Purdue University under the (C) FY17E Program Increase for Power Generation and Storage, for Lithium-Ion Battery Safety research. This proposal was selected under ONR FOA N00014-18-S-F004.ABSTRACT:Current lithium-ion batteries suffer from moderate energy density, limited cycle life, and safety issues. The emphasis of the proposed work is on developing an Indiana-based energy-storage technology incubator focusing on safer Li-ion rechargeable batteries that will demonstrate and incorporate sensors calibrated under thermal extremes to prognosticate thermal runaway during operation including two new promising technologies in electrode and separator design, along with high-throughput computational screening and design. Central to the electrode technology advancement are 2015 R&D 100 award winning structurally and morphologically tailored spherical carbon particle anodes that have shown to minimize the exothermic heat generation on the charged electrodes because of uniform solid electrolyte interphase (SEI) formation due to homogeneous local current distribution on the anode surfaces with reducedpropensity for thermal runaway by 50%. Moreover, we propose to implement multifunctional separators comprising porous SiO2 nanosheets that have shown to suppress Li dendrite formation by 60 % because of more uniform Li ion-flux distribution on the high capacity Li anode surface. The deployment of advanced electrode and separators will be performed along with sensors that have been calibrated under dynamic operating conditions relevant to Naval standards (e.g. NAVSEA 9310, UN 38.3 T3, UN 38.4T4) using a Purdue developed analytical technology called nanomechanical Raman spectroscopy. Development of material and sensing technologies will be supported by high-throughput modeling for rapid screening and accelerated design/optimization. Existing collaborations with Naval Surface Warfare Center, Crane, Naval Research Laboratory, Naval Postgraduate School, Battery Innovation Center of Indiana, Purdue Technology Transfer and industrial collaborators will form the eco-system for technology incubation. Cell prototypes (cylindrical/pouch) and safety testing will be demonstrated in collaboration with the BIC of Indiana at their testing facility. Market integration efforts for the developed technology will be pursued in collaboration with Indiana Manufacturing Institute and Indiana Economic Development Corporation. The overall emphasis is on demonstrating cell prototypes and on integration of the proposed Li-ion safety technologies in current manufacturing lines.Project managing director, who is also a managing director of Purdue University???s Discovery Park Energy Center, will help leadership in establishing a smooth liaison with various stakeholders for translation of technology from laboratory to market place. The WestGate Academy Conference and Training Center in Odon, Indiana will provide facilities for proposed collaborative commercialization activities to advance novel technologies, startup creation and veterans??? workforce development. Along with such partnership, we will leverage US???s Naval ROTC program and Purdue Veteran Success Center with national programs such as Hacking for Defense to promote veteran inclusion. PI and Co-PI???s are also part of Purdue ONR NEPTUNE project that involves collaboration among NSWC-Crane, NPS and NRL; multiple cadets and midshipmen have been already trained and coauthored on these projects. Purdue offers a STEM course on solving power and energy problems relevant to Crane with a co-instructor, who is a Crane Navy employee and Co-PI on this proposal. During this project, we plan to develop training and outreach course to improve the student understanding of batteries and their safe utilization to meet navy???s energy needs and further disseminate to Navy partners, veterans and high school students and teachers of Indiana. The overall outcome is a development of Purdue University Battery S
