The mechanism still isn't completely understood, but research could help resolve SIB lifespan problems
The world is inching closer to replacing lithium in batteries with sodium, and Cornell University researchers think they're would a way to help address stability problems in the nascent energy storage technology.
Andrej Singer, lead researcher and faculty fellow at Cornell's Department of Material Science and Engineering.degrade quickly While this discovery could help future researchers better understand how the cathodes in sodium ion batteries function, the team said they still don't quite understand the mechanism behind their formation. They were, however, able to use metallurgical modeling to predict the movement of the transient defects across the cathode.
"For centuries, blacksmiths used defect engineering in metals to create stronger and more durable materials without even realizing it," Singer said, adding that he hopes using a defect-engineering approach to sodium ion cathodes could help solve the stability problem.Lots of different industries are including sustainability in their future product roadmaps, and batteries are no different.
