Chemical causes of battery ‘capacity fade’ identified – #Lithium Ion Battery / #Manganese

When manganese ions (gray) are stripped out of a battery’s cathode (blue), they can react with the battery’s electrolyte near the anode (gold), trapping lithium ions (green/yellow).

“There’s a strict correlation between the amount of #Manganese that makes its way to the anode and the amount of #lithium that gets trapped,” said study coauthor and #Argonne scientist Daniel Abraham. “Now that we know the mechanisms behind the trapping of lithium ions and the capacity fade, we can find methods to solve the problem.”
