Anode Material for Lithium-Ion Batteries – Carbon coated iron oxide and zinc ferrite nanoparticles
The presented technology offers methods for the synthesis and preparation of carbon coated metal oxide nanoparticles for application as anodic materials in lithium-ion batteries. Carbon coated Fe2O3 and ZnFe2O4 can be used in combination with carboxymethyl-cellulose (CMC) as binder obtaining highly mechanically stable electrodes.
Commercial Opportunities: The use of these carbon coated metal oxide nanoparticles enables the realization of environmentally friendly, cost-effective, and lightweight electrochemical energy storage devices for future large scale applications. 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 electrochemical performance at high current densities and advanced cycle life. Moreover, such enhanced electrodes are easily recyclable and 100% environmentally friendly.
