| description | Nanocomposite electrodes of recently identified polyanion cathode materials comprising Li <sub>x</sub> M<sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub> {0∈ ∈x∈<∈3} [M∈=∈Co, Ni] and nanosized carbon having ~10 nm particle size were found to show remarkable improvement in their discharge capacity compared to the one prepared with acetylene black. The addition of nanosized carbon as a conductive additive offered improved initial discharge capacity of 121 mAh/g between 3.5-2.0 V vs Li/Li. The cause for such an increase could be firmly attributed to the filling up of the grain-grain contact area of the active material, facilitating the intimate grain-grain contacts in the composite structure leading to enhanced capacity delivery. As for the nanocomposite Li <sub>x</sub> Co<sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub>, it was found that at least 55% of its first discharge capacity was retained at the end of 20th cycle compared to its analogous counterpart, Li <sub>x</sub> Ni <sub>2</sub>(MoO<sub>4</sub>)<sub>3</sub>. © 2007 Springer-Verlag.
