Columbia Engineers Developed New Technique to Maximize Battery Life

An engineering team from Columbia Engineering, based in New York City and led by Yuan Yang, assistant professor of materials science and engineering, developed a new method for safely prolonging battery life. In the future the low energy density of conventional lithium-ion batteries, which in turn is responsible for the storage capacity, can be increased by using boron nitride. As a nano-coating, boron nitride is intended to stabilize solid electrolytes in lithium metal batteries and also lead to fewer short circuits.

“We decided to focus on solid, ceramic electrolytes. They show great promise in improving both safety and energy density, as compared with conventional, flammable electrolytes in Li-ion batteries,” says Yang. “We are particularly interested in rechargeable solid-state lithium batteries because they are promising candidates for next-generation energy storage.”

Boron nitride is particularly suitable due to its high compatibility with lithium metals and, due to its properties, it is also the perfect material for protection against penetration of lithium metal into solid electrolytes. The Brookhaven National Lab and the City University of New York are also involved in the new development. The aim of the research project is to develop solid state batteries with high performance and long service life.
