ELECTRODE OF HYDROGEN ABSORPTION ALLOY

摘要

PURPOSE:To enhance the current gathering characteristic and enhance the rate of utilization at the time of being incorporated in a secondary battery by constructing a two-dimensional electroconductive core with a specific thickness relative to the overall thickness. CONSTITUTION:A two-dimensional electroconductive core as a current collector is coated and filled with a paste containing powder of hydrogen absorption alloy and a highpolymer binding agent, wherein the thickness of the core shall be 10-35% of the overall thickness. This makes it practicable without bringing about drop of the strength of current collector to achieve an electrode of hydrogen absorption alloy which is equipped with an uncostly two-dimensional electroconductive core as a current collector, good current gathering performance, and a high rate of service at the time of being incorporated in a secondary battery.
