Patent ID: 6844111

Claim:
A positive electrode for an electrochemical energy storage device of high specific power comprising active element interacting with aqueous alkaline electrolyte of the electrochemical energy storage device in the process of redox charge-discharge reactions characterized in that the active element is made of electron-conductive electrolytic alloy having the composition M (l-x-y) O x H y , where M is nickel or nickel-based alloy, x is the atomic fraction of absorbed oxygen in the electrolytic alloy being within the limits of 0.01 to 0.4, y is the atomic fraction of absorbed hydrogen in the electrolytic alloy being within the limits of 0.01 to 0.4, whereby the said electrolytic alloy simultaneously fulfils the functions of current-carrying collector and of active material participating in the processes of redox charge-discharge reactions.
