Researchers at Fujian Normal University in China have developed a dual salt-based quasi-solid polymer electrolyte (DS-QSPE) that can make sodium-sulfur (Na-S) batteries a feasible solution for our large-scale energy storage demands.
Most people have only heard about lead and lithium batteries, but sodium sulfur is the future of battery technology. While lithium makes up only 0.002 percent of Earth’s crust, sodium accounts for more than 2.5 percent. It is more abundant and environment-friendly compared to lithium, but that’s not all.
Previous studies suggest that Na-S batteries could cost less, offer high energy density, be lightweight, require less water during production, withstand high-temperature conditions, and potentially have longer lifespans than conventional batteries.
So then what’s been preventing us from making and using Na-S batteries on a large scale?
