Title: SYNTHESIS OF A NOVEL MATERIAL: TITANIUM (+III) PHOSPHITE ΤI2(ΗΡO3)3, ANODE FOR LITHIUM-ION BATTERIES
Abstract:
The present invention relates to the synthesis of a novel material, titanium (III) phosphite [Τi2(ΗΡO3)3], which did not previously exist in the literature. Said compound crystallizes in a hexagonal system, space group P63/m. Said synthesis was carried out in the context of a power storage application. Up to now, in batteries, phosphites have only been used in organic forms as additives in electrolytes playing the role of stabilizers, thus enabling improved safety of use. In the literature, inorganic metal phosphites have never been used as anode material in rechargeable lithium-ion batteries. This is the subject of this work.
