SOFT SOLUTION PROCESSING FOR FABRICATION OF LITHIATED THIN-FILM ELECTRODES IN A SINGLE SYNTHETIC STEP

A process called 'soft solution processing' was used to prepare lithia ted thin-film electrodes as a cathode for lithium rechargeable microba tteries in a single synthetic step. The well crystallized Li1-xN1+xO2 films were fabricated by the electrochemical-hydrothermal treatment of nickel plates in 4 M LiOH solution at fixed temperatures around 100 d egrees C with no post-synthesis annealing. The prepared films exhibit prospective electrochemical activity; however, it is dependent on the synthetic conditions. The him formation mechanism study elucidates the effect of the synthetic conditions and also shows that soft solution processing is capable of preparing advanced inorganic materials with d esired properties through the active control of the reaction condition s.
