Lithium-ion battery electrolyte is very important to increase the kinetic energy of the Electron density, speed and stability of batteries. The use of solid electrolyte is more stable and more secure than the electrolyte liquid organic carbonates, but based in keberjalannya solid electrolyte consumption have lower ion conductivity when compared to eletrolit liquid at room temperature. Excess solid electrolyte is ionnya the better the conductivity along the rising temperature. In this study the solid electrolyte lithium phosphate-based would be made the object of research because the votes have a relatively high ion conductivity and relatively low production costs Phosphate-based lithium solid electrolyte is a good lithium conductor as well as sodium ions on the elements of the NASICON. Study on electrolyte in lithium phosphate which is based LTAP (lithium titanium Aluminum Phosphate). LTAP synthesized by sol-gel method, which then carried out the process of kalsinasi at temperatures of 900, 1000,1100 degrees Celsius. After the kalsinasi process is done the process characterization using x-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). In this study, has managed to do synthesis LTAP with composition Li1.3Al0.3Ti1.7(PO4)3 using methods sol gel. Researcher added Chitosan as a dispersing agent. Results of the analysis using x-ray Diffraction shows similar crystal phases of NASICON Li Ti Al 0.3 0.8 1.7 (PO4) 3 have been formed. The results of SEM showed the addition of solution of Chitosan makes the particle Submikron appertain in size. Chitosan capable dispersing the particles in more evenly when the process of making ltap.
