Abstract

The invention relates to a method for production of nanofibres and/or nanofibrous structures of phospho-olivine of general formula LiMPO4, where M is any of transition metals Mn, Co, Cu, Ni, V, at which in the first step a source of lithium, a source of transition metal M and a source of phosphate ions are under constant stirring added into the water, after then hydrochloric acid is added which creates by reaction with the source of transition metal M a chloro-complex of transition metal M, after all components are fully dissolved, a spinnable polymer material and lower alcohol is added. In the second step this polymer matrix is through electrostatic spinning transformed into nanofibres and/or nanofibrous structure of polymer material. In the following third step the polymer material, water, the lower alcohol and side products of reaction of the source of transition metal M with hydrochloric acid are removed through calcination from nanofibres and/or nanofibrous structure of polymer material, at the same time the source of lithium, the source of phosphate ions and the chloro-complex of transition metal M are through mutual chemical reactions transformed into phospho-olivine having general formula LiMPO4 in the form of nanofibres and/or nanofibrous structure, while through the running calcination are from nanofibres and/or nanofibrous structure also removed side products of these reactions. The result are the nanofibres which are in their whole structure formed of phospho-olivine LiMPO4. The invention further relates to nanofibres having diameter of 100 to 800 nm and length of 0,5 to 130 micrometers, which are in the whole volume formed of phospho-olivine having general formula LiMPO4, where M is any of transition metals Mn, Co, Cu, Ni, V, and to nanofibrous structures comprising said nanofibres.
