Transition metal oxides provide higher specific capacities compared to graphite, which is the actual state-of–the-art in Li-ion batteries. Nevertheless, the main drawback of these conversion materials so far has been a reduced cycling stability and limited obtainable specific capacities at elevated applied current densities.
However, these drawbacks could be overcome by utilizing the new carbon coated metal oxide nanoparticles. As a matter of fact, by using these materials it is possible to realize batteries offering a superior electro-chemical performance at high current densities and advanced cycle life. Moreover, such enhanced electrodes are easily recyclable and 100% environmentally friendly.
