<p>Composite electrode material of crystalline β-FeOOH with a (2×2) tunnel-type structure and carbon was prepared by hydrolyzing of 0.1 mol dm-3 FeCl3 aqueous solution in which carbon powder was dispersed. The composite electrode material of fineβ-FeOOH particles and Ketjen black (KB: specific surface area 1270 m2 g-1) of high specific surface area exhibited the high capacity of more than 250 mAh g-1 per β-FeOOH weight and good cycle performance at rapid charge-discharge current density of 5.0 mA cm-2 (4.5 A g-1 per β-FeOOH weight) in nonaqueous electrolytes including lithium ions. Composite electrode with KB powder exhibited high capacities compared to that with acetylene black (AB) powder. Composite electrode materials of crystalline β-FeOOH and carbon are one of the promising candidates as electrode materials for energy storage devices such as hybrid capacitors that high-power operations are required.</p>
