Anode and electrolyte chemistries for reversible, multi-electron battery technologies based on calcium

Abstract

We propose to examine the behavior of calcium as a possible anode material in batteries based on multi-electron redox couples. Toward this end we will study Ca2+ solubility and complexation in a new class of complexing ionic liquids that we previously developed for a similar successful study on magnesium. We will use Raman spectroscopy and NMR methods to characterize the complexation of Ca2+ in these designer ionic liquids and will correlate the speciation environment for Ca2+ with its electrochemical behavior. We also will explore conditions that prevent surface fouling during Ca electrodeposition and dissolution so as to enable reversible electrochemistry at these types of anodes. Our overall goal is to enable hi batteries by identifying conditions that allow for reversible Ca electrodeposition and dissolution.
