Understanding the Role of Electrode-Electrolyte Interphases at Ultra-low Temperature Li-ion Batteries for Prototype Development
Abstract
The development of lithium-ion battery that functions reliably with required power and energy to meet mission requirements under high and low temperature environments experienced by defense applications is proposed. At Purdue University, we will methodically understand, develop, and demonstrate a prototype lithium-ion pouch format batteries with >170 Wh kg#1 energy density cycling over 100 charge-discharge cycles. We will employ Purdue#s innovative cyclopentyl methyl ether (CPME)-based electrolyte coupled with tailored anodes and cathodes with essential ionic conductivity at ultralow (below -100 #) temperatures for defense applications, safely. The collaboration with Naval Research Laboratory#s (NRL) scientists to understand the interfacil properties between the electrode and electrolyte are planned. This project aims to address existing research gaps in extreme low-temperature battery applications by: 1) Methodically understanding electrode-electrolyte interphases and studying thermal safety of ultra-low temperature batteries; 2) Enhancing the cycle life at low temperatures; 3) Optimizing and integrating electrolytes and electrode materials into prototype cells to achieve desired operational batteries under extreme conditions; and 4) Preparing the next generation workforce for the Navy, DoD, DoE, and NASA by educating and training students from ROTC, active and retired military personnel (veterans, USMC Cadets, USAFA Cadets, USNA Midshipmen via providing internship/research opportunities at Purdue Uuniversity.Approved for Public Release
