Monoclinic tungsten trioxide coatings were deposited on fluorine doped tin dioxide glass substrate using a low pressure chemical vapor deposition system at 400 degrees C. Morphology analysis indicated the agglomeration of grains for 50 sccm O-2 flow rate, while for higher flow rates, the growth of islands which tend to coalescence to form a continuous film is observed. The electrochemical performance for the as-grown coating using 75 sccm 02 flow rate was similar with the one for 100 sccm presenting stability up to 500 scans. The samples indicated Li+ intercalated charge of 16 mC cm(-2), time response of 43 s and a coloration efficiency of 38 cm(-2) C-1. (C) 2015 The Electrochemical Society. All rights reserved.
