Actually, Boeing Dreamliner aircraft use lithium ion batteries as part of everyday flying. Not for propelling the plane but to support the many electrical loads on a passenger airplane. Early Dreamliners did have problems with batteries overheating, causing the plane to be grounded back in 2013 IIRC, but the design was revised and other than 1 isolated incident since then that I’m aware of, lithium ion batteries are in daily use on arguably the best passenger jet in the world today.
