Alkaline and non-aqueous proton-conducting pouch-cell batteries
Provided are sealed pouch-cell batteries that are alkaline batteries or non-aqueous proton-conducing batteries. A pouch cell includes a flexible housing such as is used for pouch cell construction where the housing is in the form of a pouch, a cathode comprising a cathode active material suitable for use in an alkaline battery, an anode comprising an anode active material suitable for use in an alkaline battery, an electrolyte that is optionally an alkaline or proton-conducting electrolyte, and wherein the pouch does not include or require a safety vent or other gas absorbing or releasing system. ...

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
