ELECTRODE FOR NON-AQUEOUS ELECTROLYTIC CELLS

摘要

An electrode for non-aqueous electrolytic cells in which a layer of an electrode-activating substance comprising an activating substance, scaly graphite and a binder is applied onto the collectors, characterized in that the central particle diameter of the graphite is larger than the central particle diameter of the activating substance and that the relationship (I) is satisfied, wherein r is a particle diameter of the activating substance, f(r) is a particle size distribution of the activating substance, d is a density of the activating substance, Sg is a BET specific surface area of the graphite, Ma is a weight of the activating substance in the electrode coating, and Mg is a weight of the graphite. The electrode provides an electrode for secondary cells which can impart a large capacity to the cells and increase the flexibility of the cells.
