Chemical and electrochemical insertion techniques were used to prepare hexagonal alkali metal bronzes. The electrochemical diffusion coefficients of Li+ were studied, as a function of composition, by using current-pulse relaxation techniques. The diffusion coefficients for LixWO3 were initially as high as 1.5 x 10-8cm2/s, when x was equal to 0.48, and decreased to 1.1 x 10-10cm2/s when x was equal to 1.13. Coefficients of 3.2 x 10-9 and 1.3 x 10-9cm2/s were found for LixK0.26WO3 at x = 0.13 and x = 0.33, respectively. A slightly different trend was observed in the LixNayWO3 system (table 106).
