A Metal-Free, Lithium-Ion Oxygen Battery: A Step Forward to Safety in Lithium-Air Batteries

Abstract

A preliminary study of the behavior of lithium-ion-air battery, where the common, unsafe lithium metal anode is replaced by a lithiated silicon-carbon composite, is reported. The results based on X-ray diffraction and galvanostatic charge-discharge analyses, demonstrate, the basic reversibility of the electrochemical process of the battery that can be promisingly cycled with a rather high specific capacity.
