    摘要： The disclosed technology generally relates to energy storage devices, and more particularly to redox batteries. In one aspect, a redox battery comprises a first half cell and a second half cell. The first half cell comprises a positive electrolyte reservoir comprising a first electrolyte contacting a positive electrode and has dissolved therein a first redox couple configured to undergo a first redox half reaction. The second half cell comprises a negative electrolyte reservoir comprising a second electrolyte contacting a negative electrode and has dissolved therein a second redox couple configured to undergo a second redox half reaction. The redox battery additionally comprises an ion exchange membrane separating the positive electrolyte reservoir and the negative electrolyte reservoir. The first half cell, the second half cell and the ion exchange membrane define a redox battery cell that is sealed in a casing.

    摘要： The disclosed technology generally relates to charging a secondary battery of an electric vehicle and more particularly to thermal management of the secondary battery associated with charging. In one aspect, a method of charging a battery of an electric vehicle includes determining that a battery temperature of a secondary battery is below a predetermined lower temperature limit suitable for charging the secondary battery at a high charging power greater than 18 kW. The method additionally includes externally applying, by contactless energy transfer means, electromagnetic energy to an energy conversion module of the electric vehicle. The method additionally includes converting the electromagnetic energy to heat and heating the secondary battery to a temperature above the lower temperature limit. The method further includes charging the secondary battery at the high charging power while maintaining the battery temperature between the lower temperature limit and an upper temperature limit at least in part by controlling a magnitude of the electromagnetic energy transferred by the contactless energy transfer means. Aspects further relate to an electric vehicle charging station, a powering system for an electric vehicle and an electric vehicle charging system.

    IPC分类号： H01M8/18

    摘要： At least some embodiments herein disclose a vanadium-based solution formed by a combination of a vanadium compound, vanadium in metallic form and an appropriate reducing agent. A manufacturing process of the combination foregoes a need of using at least one among a relatively strong reducing agent that subsequently requires removal thereof and using an electrochemical reaction to achieve sufficient chemical reduction of vanadium that is needed for the vanadium-electrolyte solution to act as the liquid electrode in the vanadium-based battery. The liquid electrode, accommodated in a battery case, has an average oxidation state of within a range of +3.3 to +3.7, which is suitable for a catholyte and an anolyte in the battery.
