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 battery (B) comprises an electrolyte in which a first element forms a redox pair with a second element, wherein the battery (B) is charged at a voltage sufficient to plate the first element at the anode (B) and wherein the voltage is insufficient to plate the second element on the anode (B). Preferred batteries include secondary batteries comprising a mixed electrolyte that includes a redox pair formed by a first element and a second element.

Mixed electrolyte battery

Perchlorate is removed and effectively destroyed in devices and methods that employ a eluting solvent in which the anion of an acid solubilizes Ti (III), which may be electrochemically generated or added in situ. Using such solvents, destruction of perchlorate is unexpectedly and several orders of magnitude faster than using solvents without solubilizing acids. In most preferred aspects, the solubilizing acid is methane sulfonic acid and/or sulfamic acid, and Ti (III) is electrochemically generated. Perchlorate destruction will then result in formation of Ti (IV), which may be present in the eluent in a subsequent elution.

Perchlorate destruction

A soil remediation system includes an electrochemical cell that is configured to provide increased mass transfer and a decreased diffusion layer between the electrodes to thereby allow formation of a homogenous lead deposit that is substantially free of dendrite formation and easily removed.

Configurations and methods of electrochemical lead recovery from contaminated soil

An electric device comprises a gelled acid electrolyte (A) in complex with a lanthanide that forms a redox pair with a second element. Preferred electric devices include batteries and especially primary batteries, while preferred acid electrolytes (A) have a sulfonic acid group. Contemplated lanthanides especially include cerium, and preferred second elements particularly include zinc. Alternatively, contemplated electric devices may comprise a gelled electrolyte (A) in which with a lanthanide forms a redox pair with zinc.

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.

A battery () comprises an electrolyte in which a lanthanide and zinc form a redox pair. Preferred electrolytes are acid electrolytes, and most preferably comprise methane sulfonic acid, and it is further contemplated that suitable electrolytes may include at least two lanthanides. Contemplated lanthanides include cerium, praseodymium, neodymium, terbium, and dysprosium, and further contemplate lanthanides are samarium, europium, thulium and ytterbium.

Lanthanide batteries

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 ().

Secondary battery with autolytic dendrites

An electric device has a plurality of cells in which in an acid electrolyte a lanthanide and zinc form a redox couple that provide a current, and in which at least two of the cells are separated by a bipolar electrode that comprises a glassy carbon or a Magneli phase titanium suboxide.

A battery comprises an acid electrolyte in which a compound provides acidity to the electrolyte and further increases solubility of at least one metal in the redox pair. Especially preferred compounds include alkyl sulfonic acids and alkyl phosphonic acids, and particularly preferred redox coupled include Co/Zn, Mn/Zn, Ce/V, Ce/Ti, Ce/Zn, and Pb/Pb.
