Photos of the Day: Why lithium-ion batteries fail

October 18, 2013 9:11 am | by EurekAlert! | News | Comments

Lithium-ion batteries are in our cellphones, laptops, and digital cameras. Few portable electronic devices exist that do not rely on these energy sources. Currently battery electrodes contain active materials known as intercalation compounds. These materials store charge in their chemical structure without undergoing substantial structural change.
