The invention concerns redox flow batteries comprising one or more electrochemical cells in fluid contact with an electrochemical balancing cell, the balancing cell comprising: (i) a first electrode comprising a gas diffusion electrode and the first electrode comprising a hydrogen oxidation catalyst, wherein the first electrode being maintained at a potential more positive than the thermodynamic potential for hydrogen evolution; (ii) a second electrode, the second electrode contacting negative electrolyte, and the second electrode being maintained at a potential sufficiently negative to reduce the negative electrolyte; (iii) a membrane dis posed between the positive electrode and the negative electrode, the membrane suitable to allow hydrogen cations to flow from the membrane to the negative electrolyte; and (iv) a means for contacting hydrogen with the first electrode.. .

Apparatus, secondary battery, manufacturing method, and electronic device

A lithium-ion secondary battery having stable charge characteristics and lifetime characteristics is manufactured. Before the secondary battery is completed, a positive electrode is subjected to an electrochemical reaction in a large amount of electrolyte solution in advance, so that the positive electrode can have stability.

Two compartment lithium sulfur cell and assembly method

Electrochemical cells for lithium-sulfur batteries include a cathode comprising a sulfur containing material, an anode comprising lithium, a separator between the anode and cathode and an interlayer extending from a perimeter of the separator in a direction perpendicular to a stacking direction. The interlayer is configured to prevent polysulfide migration from the cathode to the anode..

Dopant-driven phase transitions in correlated metal oxides

Reversible phase transitions of exceptional magnitude may be induced in correlated metal oxides by altering their chemical compositions through reversible introduction of dopant ions and electronic carriers into the correlated metal oxides. One or more catalyst electrodes may be deposited onto a surface of a film of a correlated metal oxide such as a perovskite or a transition metal oxide.
