Morphology of Alloy Elements and Electrochemical Effects of Li4Ti5O12 /Graphene Produced by Ball Milling

In the past two decades, many researchers focused their attention on metallic or semi-metallic elements which can alloy with lithium reversibly and release a high Li-storage capacity. The research samples of Li4Ti5O12/Graphene at hand were made with mechanical ball-milling technique (MA). Drops of graphene oxide were added to the powder of Li4Ti5O12, and thus enhanced the structural stability of the alloying. The main idea is to build a work electrode suitable for electrochemical test to be used in storage batteries. In order to deeply understand the behavior of graphene reaction in lithium, scanning electron microscopy (SEM) images were analyzed using algorithms from digital processing images. A complete characterization of alloying was also made, including X-Ray, transmission electron microscopy (TEM) and electrochemical noise (EN).
