摘要：

Phase-pure LiFePO4 as a cathode material for lithium ion batteries was prepared in argon, then exposed to hot air and, at last, regenerated with polypyrrole (PPy) as a reductant. Mossbauer spectroscopy and Raman spectroscopy were used to characterize the chemistry of LiFePO4 before and after regeneration. Electrochemical tests were carried out to evaluate the impacts of hot-air oxidation and regeneration on the properties of LiFePO4. (c) 2008 Elsevier B.V. All rights reserved.
