The preparation of Li4Ti5O12 nanoparticle and multiaperture film electrode

Li4Ti3O12 nanoparticles are prepared by means of Sol -Gel method. The effects of the initial pH value of the solution, the amount of the used complexing agent, the different solvents, and the calcining temperature on the purity of the obtained materials are also discussed. The X -ray analyses indicate that the obtained powder is pure Li4Ti5O12 composite oxide with spinelle structure. The size of synthesized particle at 700℃ is determined to be about 26.8 nm by means of X -ray technology. Furthermore, the average thickness of the film electrode prepared by dipping method is determined to be about 25.2um by SEM technology.
