LiFePO₄ samples were first prepared by a modified sol - gel process and then the resulting LiFePO₄ xerogel was ground and calcined in a tube furnace in an inert atmosphere in nitrogen flow. The main goal of this research work which was lowering the temperature and the time of synthesis of LiFePO₄ was achieved. It was confirmed that the material contains only a LiFePO₄ triphylite phase and that the presence of carbon resulting from pyrolysis of initial carbonaceous reagents does not affect the crystalline structure of the material.

PL

Próbki materiału LiFePO₄ przygotowano zmodyfikowaną metodą zol - żel. Otrzymany kserożel został roztarty w moździerzu i kalcynowany w piecu rurowym w atmosferze ochronnej, w przepływie azotu. Główny cel pracy jakim było obniżenie temperatury i czasu trwania procesu, został osiągnięty. Potwierdzono, że materiał ten składa się tylko z tryfilitowej fazy LiFePO₄. Dowiedziono, że węgiel obecny w próbce, pochodzący z rozkładu pirolitycznego wyjściowych soli organicznych nie wpływa na formowanie się fazy krystalicznej.
