Georgia Tech team develops melt-infiltration technique for scalable production of solid-state batteries

Green Car Congress

The new technique, reported March 8 in the journal Nature Materials , could allow large automotive Li-ion batteries to be made safer with 100% solid-state nonflammable ceramic rather than liquid electrolytes using the same manufacturing processes of conventional liquid electrolyte battery production. —Kostiantyn Turcheniuk, co-author.

The Rise and Fall of 3M’s Floppy Disk

Cars That Think

But 3M got out of the data-storage business about 28 years ago, when it transferred its floppy disk manufacturing to a spin-off called Imation. Before World War II, one company did attempt to manufacture a tape recorder in the U.S. But, it needed someone to manufacture magnetic tape for it to use. 3M manufactured a signature 5.25-inch
