Images of the cathode and anode
University of Rome Sapienza (Italy) and Hanyang University (South Korea) have teamed together to research new advancements in Lithium-Ion batteries. They have increased the battery performance from 120-150Wh/kg to 170Wh/kg(at 4.2V). This was done through a new combination of materials in the battery. The anode is made of tin-carbon and the cathode is made from lithium manganese oxide doped with cobalt and nickel. Through lab studies the combination was able to reach 100% charge-discharge efficiency. Team researchers Jusef Hassoun, ki-Soo Lee, Yang-Kook Sun, and Bruno Scrosati believe this new chemistry is best suited for electric vehicles due to the higher energy density.
Scrosati elaborated, "The battery has a high volumetric and gravimetric energy density, a high rate capability due to the nano-structured characteristics of the electrode materials, an excellent cycle life, and low cost due to the use of electrode materials based on abundant elements."
