Scientists Use ‘Smart Window’ to Observe Lithium-Ion Battery Operation

April 3, 2014

0 Comments

By using ultrathin sheets of smart-window material, nickel oxide, as the anode in a lithium-ion battery, researchers were able to see for first time exactly what happens when the battery’s lithium ions make contact with the nickel-oxide layer and how the resulting reaction spreads out from several different points. High-tech “smart windows,” which darken to […]
