Batteries are used constantly in our everyday lives, but there are challenges with existing lithium-ion technology in terms of cost and low energy density. The recent $2 billion recall of Chevy Bolts and the previous explosions of Samsung Galaxy Notes due to battery-related fires shows that safety continues to be a challenge for lithium-ion batteries. A compelling answer is solid state electrolytes (SSEs), which offer a host of advantages over the liquid electrolytes that dominate the lithium-ion market today: they are leak-proof, energy-dense, flame-resistant, contain no toxic organic solvents, and are well suited for scalable manufacturing.
This project will focus on developing printable ink-based materials for solid state SSEs that can be deposited over large areas using low-cost solution processing methods. high energy density while lowering material costs and simplifying manufacturing. The primary aim of the project is to develop an SSE battery material that can store energy more efficiently and reliably than today’s lithium-ion batteries. The scope of the project involves learning how to print battery materials, characterize ionic and electronic conductivity, defectivity using microscopy, and ultimately the production of battery devices.
Student Qualifications: Interest in working with renewable energy materials and devices and a desire to perform research to learn more about graduate school.
This project can begin in Fall 2022 on a volunteer basis (qualifying for HON 498 research credit for Barrett students) with the intention of submitting a FURI or MORE proposal for funding and continued work in Spring 2023. The desired amount of time is at least 5 hours per week, and research will take place at the ASU Research Park. A Lyft partnership allows for free rides between the Research Park and Tempe campus, and there is free parking for students who have a car.
