摘要： An amorphous carbon material, especially for an electrode of a lithium ion secondary battery, is characterized by an interlayer spacing d(002), obtained from the X-ray diffraction line assigned to the (002) plane of the carbon, of 0.345 nm to 0.365 nm, a ratio (Ps) os the number of carbon atoms involved in the layer structure to the total number of carbon atoms of from 0.54 to 0.85, and a ratio of the total nitrogen:total carbon atoms in the amorphous carbon of 0.005:1 to 0.055:1. The amorphous carbon material is prepared by applying a heat treatment to an amorphous carbon under under vacuum or inert gas atmosphere for at least 30 minutes to provide the desired crystalline structure. The carbon material may take the form of carbon fiber material, especially short carbon fibers obtained by pulverizing larger carbon fibers. A lithium ion secondary battery containing an electrode comprising such an amorphous carbon material has a large discharge capacity and high charge-discharge cycle characteristics.

摘要： This invention has the objective of providing monomer compositions with which polymers of a superior balance of various physical properties such as high oxygen permeability, high water content and a low modulus of elasticity can be obtained. It has the further objective of providing polymers and ophthalmic lenses comprised of said monomers. It is a monomer composition in which three types of monomers specified by the values of Q=(mass of Si atoms in 1 molecule of monomer)/(molecular weight of the monomer) and of Z=(number of ether oxygens in 1 molecule of monomer)+(number of hydroxyl groups in 1 molecule of monomer) are combined in suitable weight ratios.
