Complete recycle of solid-state batteries possible, thanks to polymer layers
A team of scientists at Penn State University has developed a groundbreaking method to recycle solid-state lithium batteries.
“Without the polymer layer separating them, you would have the electrode and electrolyte mixed together, which makes them hard to recycle,” Yi-Chen Lan, first author of the study and a doctoral student at PSU, said. “Fully recovered full cells with Li-metal and LTO anodes show 92.5% and 93.8% of original discharge capacity at 0.05 C and room temperature,” the study authors note. “While we’re not quite there yet, the long-term goal is to apply this innovation to larger batteries that could be used in devices like cell phones and laptops, once all-solid-state technology becomes more prevalent,” Lan said.
