Use of strontium titanate (SrTiO3) as an anode material for lithium-ion batteries. Johnson, D. C. & Prieto, A. L. Journal of Power Sources, 196(18):7736–7741, September, 2011.
Paper doi abstract bibtex Strontium titanate nanoparticles have been synthesized using a combination of sol-precipitation and hydrothermal techniques for subsequent testing as an anode material for lithium-ion batteries. The potentials associated with lithiation are 0.105V and 0.070V vs. Li/Li+ and 0.095V and 0.142V vs. Li/Li+ during de-lithiation. These potentials are significantly lower than the 1.0V to 1.5V vs. Li/Li+ typically reported in the literature for titanates. In an attempt to improve the lithiation and de-lithiation kinetics, as well as capacity retention, SrTiO3 nanoparticles were platinized using a photoinduced reduction of chloroplatinic acid. No significant changes in the morphology or crystal structure of the platinized nanoparticles were observed as a result of the reduction reaction. The voltage profile, charge and discharge kinetics, and cyclability of the platinized SrTiO3 nanoparticles are compared to that of the non-platinized SrTiO3 nanoparticles.
