Estimating the term…
In a pasted hydrogen-absorbing alloy electrode of this invention, an active material layer made from a mixture of a hydrogen-absorbing alloy powder, a composite particle powder including carbon particles and a rare earth compound for partially coating surfaces of the carbon particles, and a binder is formed on a current collector. When this pasted hydrogen-absorbing alloy electrode is used in an alkaline storage battery, the alkaline storage battery can attain small increase of the internal pressure during charge, large discharge capacity in high rate discharge and good charge-discharge cycle performance.
A pasted hydrogen-absorbing alloy electrode for an alkaline storage battery comprising an active material layer formed on a current collector from a mixture including a hydrogen-absorbing alloy powder, a conductive agent and a binder, the conductive agent being a composite particle powder made from carbon particles and a rare earth compound partially coating surfaces of the carbon particles.
