Diederichsen, Kyle M. published the artcileElectrolyte additives to enable nonaqueous polyelectrolyte solutions for lithium ion batteries, COA of Formula: C10H22O5, the main research area is crown ether nonaqueous polyelectrolyte solution lithium ion battery.
Nonaqueous polyelectrolyte solutions, in which a neg. charged macromol. neutralized by lithium is dissolved in nonaqueous solvents, have shown promise as potential high transference number electrolytes. However, in battery-relevant carbonate solvents (ethylene carbonate/dimethyl carbonate blends), it has been shown that lithium ions do not readily dissociate from easily synthesized sulfonated polymers, despite the solvent’s high dielec. constant (∼50). In this work, a range of additives are screened to improve conductivity, and we demonstrate that the addition of less than 5 vol% of 15-crown-5 achieves an order of magnitude conductivity increase by selectively improving lithium dissociation Utilizing the optimized electrolyte, we show that polyelectrolyte solutions may be directly substituted for a standard electrolyte with com. electrodes in a graphite/LiFePO4 cell, providing further motivation for future study of these new electrolytes.
