Researches On Copper. History & Metallurgy, Fathi Habashi Feb 2009

Researches On Copper. History & Metallurgy, Fathi Habashi

Fathi Habashi

The present volume is a collection of selected papers dealing with the extractive metallurgy of copper published by the author and his coworkers. They are reproduced here in a facsimile edition in 240 pages. In addition ten new chapters were specially written in 150 pages. The book is fully illustrated by many colored pictures, flowsheets, and diagrams. It is hoped that it will be useful for students, engineers, chemists, geologists, and for research workers.

Synthesis Of The Lifepo_4 By Co Reduction:Reaction Mechanism And Kinetics, Yun-Hua Chen, Yong Yang Nov 2008

Synthesis Of The Lifepo_4 By Co Reduction:Reaction Mechanism And Kinetics, Yun-Hua Chen, Yong Yang

Journal of Electrochemistry

LiFePO4 cathode material was synthesized by CO reducing FePO4 and LiOH precursors.The structure,morphology and electrochemical performances of such LiFePO4 material were characterized by XRD,SEM and charge-discharge tests.It was shown that the particle size of the LiFePO4 synthesized with 5% excess of LiOH in the precursor was about 200 nm.By carbon coating,the LiFePO4 electrode was able to deliver a reversible capacity of 158 mAh·g-1 at 0.1C discharge rate.Temperature-programmed X-ray diffraction was employed to monitor the reaction during the formation of LiFePO4,and Li3Fe2(PO4)3 was found to be an intermediate by analyzing the time-resolved XRD patterns.Kinetic study indicates that nucleation and their growth …
