Abstract
The present invention relates to crystalline nanometric olivine-type LiFe1-xMnxPO4 powder with 0<x<1, with small particle size and narrow particle size distribution. The fine particle size is believed to account for excellent high-drain properties, while minimizing the need for conductive additives. The narrow distribution facilitates the electrode manufacturing process and ensures a homogeneous current distribution within the battery.
