Product and method for the processing of precursors for lithium phosphate electrode active materials

Abstract From the Canadian patent

Methods for producing an electrode active material precursor comprising: a) , producing a mixture comprising particles of lithium hydrogen phosphate having , a first average particle size and a metal hydroxide, having a second average particle size; and b) grinding said mixture in a jet mill for a period of time suitable to produce a generally homogeneous mixture of particles having a third average size smaller than said first average size. The precursor may be used as a starting material for making electrode active materials for use in a battery, comprising lithium, a transition metal and phosphate or a similar , anion.
