Abstract (first 170 chars)

The present invention discloses a very simple, easy and inexpensive way for the preparation of Li-battery worthy electrode material from natural mud. Particularly, the present invention discloses an anode material for enhanced lithium ion battery applications comprising of major fraction of γ-Fe 2 O 3 and rest of Fe 2 TiO 4 , SiO2 and Al 2 O 3 wherein said material is extracted directly from red mud by a simple process of magnetic separation without any further processing.
