Claim Text:
1. An electrode comprising a cathode mix having an olivine-type lithium iron phosphate being applied to a current collector, wherein the olivine-type lithium iron phosphate is composed of secondary particles having a mean particle diameter (D50) of 5 to 100 μm, and the secondary particles are formed by aggregation of primary particles having a mean particle diameter (D50) of 50 to 550 nm, wherein the primary particles are aggregated via physical bonds to form the secondary particles, wherein the olivine-type lithium iron phosphate is LiFePO wherein the secondary particles have a porosity of 18 to 22.9%, and a portion of the secondary particles are deformed and converted into primary particles, wherein the primary particles are prepared by a supercritical hydrothermal method, and wherein the olivine-type lithium iron phosphate has a bulk density of 0.5 to 1.5 g/mL.
