Abstract: Provided are a cathode active material coated with a fluorine-doped spinel-structured lithium metal manganese oxide, a lithium secondary battery including the same, and a method for preparing the same. The cathode active material has improved chemical stability and provides improved charge/discharge characteristics at elevated temperature (55-60° C.) and high rate. The cathode active material allows lithium ions to pass through the coating layer with ease and is chemically stable, and thus may be used effectively as a cathode active material for a high-power lithium secondary battery.

Abstract: An expandable polystyrene bead production method, which is a two-step process, is disclosed. The method includes obtaining suspendable, homogenous micropellets from a mixed composition prepared by mixing graphite particles with a styrene-based resin and extruding the composition, and carrying out seed polymerization by suspending graphite-containing micropellets in water and adding a styrene-based monomer and an aromatic hydrocarbon having 6 to 10 carbon atoms, and impregnation by adding a blowing agent. The produced expandable polystyrene beads, which contain graphite particles, are considerably low in thermal conductivity. In addition, the expandable polystyrene beads exhibit a little change in the thermal conductivity over time due to the use of the graphite particles, so that the heat insulation property can be sustained for an extended period of time.
