Abstract
The method includes mixing and heat-treating carbon nanotubes, a water-soluble polymer dispersant, and an iron (Fe) precursor to form an iron oxide-carbon precursor; mixing and calcining a lithium precursor and the iron oxide-carbon precursor at a temperature of 500° C. or higher to form lithium-iron oxide particles; and heat-treating a mixture containing the lithium-iron oxide particles and a lithium difluoro(oxalato)borate under an oxygen-containing gas atmosphere at a temperature of less than 300° C. to form a lithium-iron oxide coated with a lithium difluoro(oxalato)borate-containing layer.
