Abstract

A carbon material containing graphite particles. The graphite particles are natural graphite coated with an amorphous carbonaceous substance. When the carbon material is included in an electrode fabricated by adding a binder resin and a dispersion medium to the carbon material to form a slurry, applying the slurry to a metal current collector, drying the applied slurry to form an active material layer on the metal current collector, and then pressing the active material layer such that the active material layer has a density of 1.65 g/cm3, the carbon material has an orientation parameter intensity ratio I(002)/I(110) of from 200 to 1200, where I(110) is a peak intensity corresponding to a lattice plane (110) and I(002) is a peak intensity corresponding to a lattice plane (002), and both I(110) and I(002) are obtained by a wide-angle X-ray diffraction measurement.

Abstract

Monoalkyl tin triamide compounds having purity of at least about 99 mol % and the chemical formula RSn(NMe2)3 are described. R1 is selected from RA, RB and RC; RA is a primary alkyl group having about 1 to 10 carbon atoms, RB is a secondary alkyl group having about 3 to 10 carbon atoms, and RC is a tertiary alkyl group having about 3 to 10 carbon atoms; each R2 is independently an alkyl group having about 1 to 10 carbon atoms; and a content of R1Sn(NR22)2(N(R2)CH2NR22) is less than about 1 mol %. Methods for synthesizing, purifying, and storing these compounds are also provided. The monoalkyl tin compounds may be used for the formation of high-resolution EUV lithography patterning precursors and are attractive due to their high purity and minimal concentration of dialkyl tin and other tin impurities.
