Abstract:
PURPOSE:To increase the maximum discharge capacity and decrease the cycle number reaching the maximum discharge capacity by continuously orienting conductive metal powder in parallel or almost in parallel in the cross section structure of a hydrogen storage electrode to form a micro current collector. CONSTITUTION:10-30g of conductive metal powder (flaky copper powder) whose mean major axis is 45-100mum and mean minor axis is 1-20mum is mixed with 100g of hydrogen storage alloy powder pulverized in 45mum or less. The mixed powder is filled in a mold, then press-molded at 100Mpa to form a 30mmX40 mmX0.6mm sheet. A sheet-shaped hydrogen storage electrode with cross section structure in which the conductive metal powder is arranged (oriented) in a continuously contacted state in the parallel or almost parallel direction to an electrode surface (in the vertical or almost vertical direction to the press molding direction) is obtained. In this cross section structure, the conductive metal powder is capable of efficiently collecting current from the hydrogen storage alloy powder.
