摘要:
An electrode comprising as active material a graphite composition composed of high-crystalline graphite containing at least one component having interlayer spacings in a first predetermined range and low-crystalline graphite containing at least one component having interlayer spacings in a second predetermined range is produced by blending the high-crystalline graphite and the low-crystalline graphite to obtain a mixture, and baking the mixture.
摘要:
A method for the manufacture of a pyrolytic graphite with high crystallinity comprises the deposition of graphite directly onto a catalytic substrate by thermal decomposition of a carbon-containing material at low temperatures. Also disclosed is an electrode comprising graphite as an active material and an electrode substrate as a current collector unified, said graphite being pyrolytic graphite that is deposited on a metal electrode substrate with catalytic properties so as to cover said metal electrode substrate by the said method. Further disclosed is a battery comprising a pair of positive and negative electrodes, at least one of which is made of graphite as its electrode active material.
摘要:
There is described the production of a graphite material for use in a negative electrode of a non-aqueous secondary battery. The graphite material is prepared to include both a high-crystalline graphite and a low-crystalline graphite, the high-crystalline graphite having interlayer spacings d002 in the range of 0.3354 to 0.340 nm.
摘要:
A carbon electrode is prepared by the steps of subjecting a hydrocarbon to vapor phase pyrolysis to form a pyrolytic carbon having a specific X-ray diffraction peak half-width; contacting the pyrolytic carbon with lithium vapor to obtain a lithium-intercalated pyrolytic carbon; and forming the lithium-intercalated pyrolytic carbon into an electrode. The pyrolytic carbon is preferably formed on a substrate, especially an iron group metal, and the electrode may be used with advantage as cathode in a non-aqueous secondary battery.

摘要:
A process for producing a graphite electrode which comprises forming a deposition layer (8) of fine globular graphite particles on a substrate (4) first, and subsequently the step of forming a metal film (9) of an iron group element or an alloy thereof on the deposition layer and forming a graphite layer (10) on the metal film to obtain an electrode having the graphite layer supported on the substrate.
