New Stabilization Method Could Revolutionize Solid State Batteries
Researchers at the Brookhaven National Laboratory and MIT have developed a new way to add more energy into solid-state batteries without increasing their volume or weight. Unlike with lithium ion batteries where a liquid electrolyte carries the charge between electrodes, a solid electrolyte layer is present in solid-state batteries. While this solid layer does away with the fire hazard linked to li-ion batteries and helps deliver more energy, the instability at the boundary between the two electrodes and the solid electrolyte layer shortens battery lifetime. The researchers developed a new technique that involves the elimination of any carbon dioxide present…
