Insertion characteristics of anatase electrodes were studied on single-crystal and polycrystalline electrodes of different microstructures. The electrode microstructure affects both the accessable coefficient x and the reversibility of the process. The insertion activity is the highes for polycrystalline electrodes with crystal dimentions 10-8 m and deteriorates for higher as well as smaller crystals. The Li+ diffusion coefficient decreases with increasing x and ranges from 10 15 and 10 18 cm2 s1.
