    摘要: A fibrous anisotropic permanent magnet is disclosed comprising fibers composed of an alloy comprising at least one of a rare earth metal selected from Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B, said fibers having a mean diameter of from 50 to 1,000 .mu.m and exhibiting magnetic anisotropy. The fibrous anisotropy permanent magnet is prepared by extruding a molten alloy comprising at least one of Nd, Pr, Dy, Ho, Tb, La, and Ce; Fe or Fe and Co; and B in an oil to quench-solidify the molten alloy into a fibrous form.Since the fibrous magnet exhibits excellent anisotropic magnetic characteristics in the lengthwise direction of the fiber axis in the quench-solidified state, the magnet is particularly useful as a magnetic powder material for an anisotropic bond magnet.

    摘要: Disclosed is carbonaceous material for a negative electrode of a lithium secondary battery and a lithium secondary battery made using the carbonaceous material. The carbonaceous material includes a silica film coated on a surface of carbon particles of the carbonaceous material, thereby minimizing both direct contact of the carbon particles with an organic electrolyte and cointercalation of the organic electrolyte and lithium ions within a structure of the carbon. The lithium secondary battery includes a negative electrode deposited with the carbonaceous material, a counterpart electrode made of lithium metal, electrolyte made of a propylene carbonate/ethylene carbonate solution containing 1 mol/l of LiPF8, and a polypropylene separator.
