摘要： An organic positive electrode active material for aqueous redox flow batteries, and more particularly, to technology of applying an organic positive electrode active material to make up for the drawbacks of conventional aqueous redox flow batteries. An aqueous redox flow battery to which a particular positive electrode active material is applied has no problems regarding metal deposition, and can also be useful in realizing a high energy density because the positive electrode active material may be used at high concentration due to an increase in solubility in a solvent, attaining a high working voltage, and enhancing energy efficiency. Also, the aqueous redox flow battery has excellent economic feasibility because an expensive organic electrolyte is not used.

Compared with Mg-ion or Mg-air chemistries, the Mg—Br2 system features fast kinetics and good cyclability. In one embodiment, the present invention provides a rechargeable non-aqueous, dual-electrolyte scheme. In one embodiment, the anolyte consisted of Mg(TFSI)2 dissolved in a monoglyme and diglyme mixture, whereas the catholyte was composed of Mg(TFSI)2 in PYR14TFSI ionic liquid mixed with active bromine species. When Mg was used as the anode, an open circuit voltage of 3.0 V (vs. Mg2+/Mg) was measured.

摘要： An electrical circuit designed to dynamically connect or disconnect an electrochemical cell to or from an electrical load based on the measured value of the discharge voltage generated by the cell is discussed. When the measured discharge voltage of an electrochemical cell is less than the threshold voltage, the cell is disconnected from an electrical load and when the discharge voltage is the same as, or greater than, the threshold voltage, the electrochemical cell is connected to an electrical load. The circuit is configured so that the value of the threshold voltage increases from an initial value when the electrochemical cell is first disconnected from the electrical load.

摘要： Voltage delay in an active metal anode/liquid cathode battery cell can be significantly reduced or completely alleviated by coating the active metal anode (e.g., Li) surface with a thin layer of an inorganic compound with Li-ion conductivity using chemical treatment of Li surface. Particularly, preferred examples of such compounds include lithium phosphate, lithium metaphosphate, and/or their mixtures or solid solutions with lithium sulphate. These compounds can be formed on the Li surface by treatment with diluted solutions of the following individual acids: H3PO4, HPO3 and H2SO4, their acidic salts, or their binary or ternary mixtures in a dry organic solvent compatible with Li, for instance in 1,2-DME; by various deposition techniques. Such chemical protection of the Li or other active metal electrode significantly reduces the voltage delay due to protected anode's improved stability toward the electrolyte.
