New Energy Materials Findings Has Been Reported by Investigators at Helmholtz Institute (ZnFe2O4-C/LiFePO4-CNT: A Novel High-Power Lithium-Ion Battery with Excellent Cycling Performance)

By a News Reporter-Staff News Editor at Energy Weekly News -- Fresh data on Energy Materials are presented in a new report. According to news reporting from Ulm, Germany, by VerticalNews journalists, research stated, "An innovative and environmentally friendly battery chemistry is proposed for high power applications. A carbon-coated ZnFe2O4 nanoparticle-based anode and a LiFePO4-multiwalled carbon nanotube-based cathode, both aqueous processed with Na-carboxymethyl cellulose, are combined, for the first time, in a Li-ion full cell with exceptional electrochemical performance."

The news correspondents obtained a quote from the research from Helmholtz Institute, "Such novel battery shows remarkable rate capabilities, delivering 50% of its nominal capacity at currents corresponding to approximate to 20C (with respect to the limiting cathode). Furthermore, the pre-lithiation of the negative electrode offers the possibility of tuning the cell potential and, therefore, achieving remarkable gravimetric energy and power density values of 202 Wh kg(-1) and 3.72 W kg(-1), respectively, in addition to grant a lithium reservoir."

According to the news reporters, the research concluded: "The high reversibility of the system enables sustaining more than 10 000 cycles at elevated C-rates (approximate to 10C with respect to the LiFePO4 cathode), while retaining up to 85% of its initial capacity."
