Battery with hydrogen absorbing material of the formula LnM5

摘要

An electrochemical energy conversion device, i.e. a galvanic cell using a hydrogen absorbing material to provide either a source of energy, or to absorb hydrogen to avoid overpressure in the cell. This hydrogen absorbing material is a compound of the formula LnM5 in which Ln represents a lanthanide metal and M is either cobalt or nickel.
