Molecular mayhem at root of battery breakdownScientists at Pacific Northwest National Laboratory (PNNL) have uncovered a molecular game of musical chairs that hurts battery performance.In an article published in Nature Nanotechnology, the researchers demonstrate how the excitation of oxygen atoms that contributes to better performance of a lithium-ion battery also triggers a process that leads to damage, explaining a phenomenon that has been a mystery to scientists.The research pinpoints the science behind one barrier on the road to creating longer-lived, higher-capacity rechargeable lithium-ion batteries. It’s an unexpected finding about a process that takes place every day in the batteries that power cell phones, laptop computers, and electric cars.Read more. -- source link
