| titleOfInvention | A kind of hydrothermal preparing process of positive electrode material of lithium secondary cell fluorophosphoric acid cobalt lithium |
| abstract | The invention discloses a kind of lithium secondary battery high voltage, high-energy-density positive pole material fluorophosphoric acid cobalt lithium Li 2 CoPO 4 The hydrothermal preparing process of F.It is characterized in that prepared method comprises the following steps: by soluble in water to the phosphoric acid root of certain stoichiometric proportion, cobalt source, lithium source and fluorine source compound, it is transferred to after being uniformly mixed in teflon-lined reactor, at 160 ~ 220 DEG C, after hydro-thermal reaction 5 ~ 20h, is cooled to room temperature dried presoma；By above-mentioned presoma under an inert atmosphere, after 200 ~ 400 DEG C of pre-burnings and 500 ~ 750 DEG C of calcinings, target product fluorophosphoric acid cobalt lithium after being cooled to grinding at room temperature, is i.e. obtained.The method disposably adds material, and technological operation is simple, and product purity is high, and process control and properties of product all have good repeatability, prepared Li 2 CoPO 4 F material granule good dispersion, primary particle is nanoscale, and offspring is that micron order, size and pattern are uniform.Material potential plateau prepared by application the method is high, show the chemical property of excellence, particularly there is in terms of charge-discharge performance the advantage that other synthetic method is incomparable, by prospect fine for the practical unlatching for this kind of high-energy-density positive electrode. |
