Currently, the biggest hurdle for electric vehicles, or EVs, is the development of advanced battery technology to extend driving range, safety and reliability.
New research has shown how a novel lithium-based electrolyte material (Li9N2Cl3) can be used to develop solid-state batteries that charge faster and store more energy than conventional designs. Experiments revealed the solid-electrolyte was not only stable in normal air environments, but it also inhibited the growth of dendrites — dangerous, branchlike formations that cause batteries to catch fire.
“The material’s dry air stability, efficient lithium-ion transport, and high compatibility toward metallic lithium are crucial advances. It’s the best of both worlds,” he said. “It offers all the performance benefits of liquid-electrolyte batteries that we use every day, but it’s safer and more reliable.”
