Abstract

Phospho-olivine LiFePO₄ is a excellent candidate for the next generation of rechargeable lithium battery that is environmentally benign and inexpensive, In this study, we exploited the advantages of hydrothermal synthesis at low energy cost. To avoid oxidization of Fe²⁺, LiFePO₄ was prepared with high purity FeSO₄ and ascorbic acid was added as reducer.
