A power cell (A) has an electrolyte that includes a reodox pair comprising cerium. The electrolyte in preferred cells is an acid electrolyte that comprises a element ion complexed by an organic acid or a chelating agent, and contemplated electrolytes may further include a compound that reduces the hydrogen overpotential. Where the power cell comprises a plurality of cells (B), preferred configurations may include glassy carbon as bipolar electrolytes.

Cerium batteries

A load leveling battery () comprising an electrolyte that includes a cerium zinc redox pair wherein preferred electrolytes are acid electrolytes, and most preferably comprise methane sulfonic acid. Contemplated load leveling batteries () have an open circuit voltage of at least 2.4 Volt per cell. Such batteries are useful at power grid substations () and commercial and industrial applications were large amounts of power are used. Preferred capacity is at least 100,000 kWh, more preferably 250,000 kWh.

Load leveling battery and methods therefor

A battery () comprises a cell having a cathode compartment () that includes an element that is oxidized during charging of the battery (), wherein the oxidized element forms a salt with an acid and thereby increases the H+ concentration in the cathode compartment () sufficient to promote an H+ flux into the anode compartment () across the separator (), wherein the H+ flux across the separator () is sufficient to disintegrate a zinc dendrite proximal to the separator ().
