New Technique Could Help Produce Lighter, Safer, and More Energy-Dense Batteries
Written by AZoMMar 9 2021
A new fabrication technique could allow solid-state automotive lithium-ion batteries to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes.
The melt-infiltration technology developed by materials science researchers at the Georgia Institute of Technology uses electrolyte materials that can be infiltrated into porous yet densely packed, thermally stable electrodes.
The one-step process produces high-density composites based on pressure-less, capillary-driven infiltration of a molten solid electrolyte into porous bodies, including multilayered electrode-separator stacks.
While the melting point of traditional solid state electrolytes can range from 700 degrees Celsius to over 1,000 degrees Celsius, we operate at a much lower temperature range, depending on the electrolyte composition, rough
A new fabrication technique could allow all-solid-state automotive lithium-ion batteries (ASSLBs) to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes. The new technique, reported March 8 in the journal Nature Materials, could allow large automotive Li-ion batteries to be made safer.
