Activation of laves phase-related bcc metal hydride alloys for electrochemical applications

Laves phase-related bcc metal hydride alloys historically have limited electrochemical capabilities. Laves phase-related bcc metal hydride alloys are provided herein with greater than 200 mah/g capacities and commonly at or greater than 400 mah/g capacities. ... Ovonic Battery Company Inc

Method of calibrating state-of-charge in a rechargeable battery

Provided are processes for the calibration of a battery system whereby a secondary battery is formed with an anode, a cathode, or both that includes two or more active materials that differ by at least one chemical or physical parameter. The presence of the two or more differing alloys in the system introduces at least one inflection point in the charge/discharge curves characterizing the system. ... Ovonic Battery Company Inc
