Nanomaterials of the JT phase of the titanium oxide TiO2-x, where 0≦x≦1 having as a building block a crystalline structure with an orthorhombic symmetry and described by at least one of the space groups 59 Pmmn, 63 Amma, 71 Immm or 63 Bmmb. These nanomaterials are in the form of nanofibers, nanowires, nanorods, nanoscrolls and / or nanotubes. The nanomaterials are obtained from a hydrogen titanate and / or a mixed sodium and hydrogen titanate precursor compound that is isostructural to the JT crystalline structure. The titanates are the hydrogenated, the protonated, the hydrated and / or the alkalinized phases of the JT crystalline phase that are obtained from titanium compounds such as titanium oxide with an anatase crystalline structure, amorphous titanium oxide, and titanium oxide with a rutile crystalline structure, and / or directly from the rutile mineral and / or from ilmenite. The titanates are submitted to dynamic thermal treatment in an inert, oxidizing or reducing atmosphere to produce the JT phase of the TiO2-x, where 0≦x≦1 with an orthorhombic structure.

The invention belongs to lithium battery materials, and specifically relates to a method for preparing a lithium titanate material, comprising the following steps: step 1, adding tetrabutyl titanate into absolute ethanol and stirring evenly to form a titanium alcohol solution; step 2, adding acetic acid Lithium is added to the titanic acid solution and stirred evenly to form a mixed solution; step 3, the titanium monoxide powder is added to the mixed solution by low-temperature ultrasound for 1-2 h to obtain a suspension; step 4, the suspension is sprayed to the constant temperature reaction kettle In the process, the coated titanium monoxide particles are obtained after sealing deposition and pressure relief cooling; step 5, the coated titanium monoxide particles are placed in the sealed reaction kettle for 1-3 hours under constant pressure, and then water vapor is introduced to carry out the sealed and pressurized reaction 2- 3h, after the pressure was released, it was sealed and sintered to obtain lithium titanate particles. The invention solves the problem of poor electrical conductivity of the existing lithium titanate material, uses titanium monoxide as the inner core, and uses lithium titanate as the surface coating layer to ensure that the prepared material has oxygen deficiency, improves the mobility of electrons, and thus improves the the conductivity.
