Energy crisis encourages the development of new and renewable energy, which is the source of energy is converted into electrical energy and to support it we needs an energy storage specially in the form of batteries. In this research besides being a energy storage, batteries are expected to perform a self-charging by integrating piezoelectric material that converts mechanical energy into electrical energy. So that the secondary battery can also be used in remote areas that can not be connected to the electricity network. <br /> <br /> <br /> Barium Titanate (BaTiO3) is used as a material for ceramic battery. Barium titanate chosen because this material is an electronic ceramic material that has perovskite structure, have a low Curie temperature, and can be a ferroelectric. Synthesis of barium titanate done by sol-gel method with optimum calcination temperature 8500C. The addition of chitosan as a dispersant agent has successfully made barium titanate composed of nanoparticles with sizes below 100 nm. <br /> <br /> <br /> Modification of barium titanate nanostructure with the addition of sulfur performed using sulfur-reactor method and solid state method, produces BaTi5O11 and BaTi2O5 as dominant compounds with perovskite structure. The addition of sulfur have not produced a new compounds phase, but sulfur has successfully entered into barium titanate nanostructure interstitially and change the crystal structure become monoclinic structure.
