The growing demand for new energy sources has been a stimulus for extensive research in the area
of materials, especially in high-performance solid-state batteries. Recently, sodium trititanate (Na2Ti3O7), an
inorganic chemical compound, has received attention due to its effectiveness in ion exchange and catalytic
properties. However, its application as an electrolyte in solid-state batteries is limited due to its low electrical
conductivity. To overcome this limitation, lithium-doped Na2Ti3O7 nanoparticles were synthesized in different
proportions, ranging from 0% to 5% by mass, using the microwave-assisted hydrothermal method. Samples
were extensively characterized by XRD, 0%, 1% and 5% samples were also analyzed by DTA, Raman
spectroscopy and complex impedance spectroscopy. Notably, the 5% lithium doped sample exhibited an
electrical resistance approximately one order of magnitude lower than the undoped material. These promising
results highlight the potential of doped sodium titanate as a viable component for high-performance solidstate batteries due to its enhanced structural and conductive properties.
