摘要： Provided is an olivine-type lithium iron phosphate composed of secondary particles having a mean particle diameter (D50) of 5 to 100 μm, formed by aggregation of primary particles having a mean particle diameter (D50) of 50 to 550 nm, wherein the primary and secondary particles have a composition represented by Formula I below and the secondary particles have a porosity of 15 to 40%: Li1+aFe1-xMx(PO4-b)Xb (I) wherein M, X, a, x and b are as defined above.The olivine-type lithium iron phosphate is in the form of secondary particles, thus imparting a high bulk density to lithium secondary batteries and exhibiting superior process efficiency due to shortened mixing time, when used to fabricate the lithium secondary batteries. Furthermore, the olivine-type lithium iron phosphate has the high porosity, thus allowing at least a portion of the secondary particles to be deformed and converted into primary particles in the process of pressing to fabricate electrodes and preventing deterioration in ionic conductivity due to the large particle diameter.
摘要翻译：本发明提供一种由平均粒径（D50）为5〜100μm的二次粒子构成的橄榄石型磷酸铁锂，其通过聚集平均粒径（D50）为50〜550nm的一次粒子而形成，其中，二次粒子具有下述式I所示的组成，二次粒子的孔隙率为15〜40％：Li1 + aFe1-xMx（PO4-b）Xb（I）其中M，X，a，x和b分别为以上定义。橄榄石型磷酸铁锂是二次粒子的形式，因此当锂二次电池用于制造锂二次电池时，由于缩短了混合时间，因此赋予锂二次电池高的堆积密度，并表现出优异的工艺效率。此外，橄榄石型磷酸铁锂具有高孔隙率，从而允许至少一部分二次粒子在压制过程中变形并转化为一次粒子，以制造电极，并防止由于大的离子导电性导致的劣化粒径。
