抄録	Needle-like α-Fe2O3 particles with the length of 2 µm and the width of 250 nm were prepared by thermal decomposition of β-FeOOH and the electrochemical performances in the all-solid-state cells were examined. The cell using needle-like particles with acetylene black as a conductive additive showed the first discharge capacity of about 700 mAh g−1 at the current density of 0.064 mA cm−2. The lithium ion and electron conduction path of the electrode was improved by using vapor grown carbon fiber as a conductive additive. The needle-like α-Fe2O3 particles were compared with α-Fe2O3 spherical particles; the suitability for the active material of all-solid-state batteries was investigated.
