Electrochemical properties are investigated for thin film electrode of NaxCoO2, which was fabricated by pulsed laser deposition. A high rate of 400 C was realized in the film together with a fine cyclability where its capacity after 1000 cycles remains 84.4 of the initial one. The NaxCoO2 thin film exhibits a clear sign of the structural phase transition induced by Na intercalation even at the high rate of 200 C. This observation indicates bulk nature of the rapid and highly-reversible Na intercalation in NaxCoO2.
