Abstract: An olivine-type positive active material for a lithium battery, a lithium battery having the olivine-type positive active material, and a method of manufacturing the olivine-type positive active material are provided. The olivine-type positive active material includes a plurality of particles represented by LixMyM?zXO4-wBw. M and M? are independently an element selected from the group consisting of Fe, Ni, Co, Mn, Cr, Zr, Nb, Cu, V, Mo, Ti, Zn, Al, Ga, Mg, B, and the combination thereof, X is one element selected from the group consisting of P, As, Bi, Sb, and the combination thereof, B is one element selected from the group consisting of F, S, and the combination thereof, 0<x?1, 0<y?1, 0<z?1, 0<x+y+z?2, and 0?w?0.5. The particle is a secondary particle having a plurality of primary particles, a first carbon coating layer is on the surface of the primary particle and a second carbon coating layer is on the surface of the secondary particle, and carbon is dispersed inside the primary particle.

Abstract: The present invention relates to an acrylamide-based mesoporous polymer and its preparation method, where the acrylamide-based mesoporous polymer is fabricated by a simple preparation method to have uniform minute pores controllable in pore size and thereby applicable to a wide variety of fields. The acrylamide-based mesoporous polymer includes at least one of a defined repeating unit and contains a plurality of pores having a diameter of 2.0 to 10.0 nm in the solid state.

Abstract: An apparatus and method for packet routing in a high-speed packet routing system. The apparatus includes an input unit and a control unit. The input unit temporarily stores an input packet and outputs the temporarily stored input packet to an output port determined by a previous router. The control unit determines an output port of a next router for the input packet.
