    摘要： Embodiments described herein relate generally to electrochemical cells having high rate capability, and more particularly to devices, systems and methods of producing high capacity and high rate capability batteries having relatively thick semi-solid electrodes. In some embodiments, an electrochemical cell includes an anode and a semi-solid cathode. The semi-solid cathode includes a suspension of an active material of about 35% to about 75% by volume of an active material and about 0.5% to about 8% by volume of a conductive material in a nonaqueous liquid electrolyte. An ion-permeable membrane is disposed between the anode and the semi-solid cathode. The semi-solid cathode has a thickness of about 250 µm to about 2,000 µm, and the electrochemical cell has an area specific capacity of at least about 7 mAh/cm 2 at a C-rate of C/4. In some embodiments, the semi-solid cathode slurry has a mixing index of at least about 0.9.

    摘要： Embodiments described herein relate generally to devices, systems and methods of producing high energy density batteries having a semi-solid cathode that is thicker than the anode. An electrochemical cell can include a positive electrode current collector, a negative electrode current collector and an ion-permeable membrane disposed between the positive electrode current collector and the negative electrode current collector. The ion-permeable membrane is spaced a first distance from the positive electrode current collector and at least partially defines a positive electroactive zone. The ion-permeable membrane is spaced a second distance from the negative electrode current collector and at least partially defines a negative electroactive zone. The second distance is less than the first distance. A semi-solid cathode that includes a suspension of an active material and a conductive material in a nonaqueous liquid electrolyte is disposed in the positive electroactive zone, and an anode is disposed in the negative electroactive zone.

    摘要： A method and system for monitoring a state of charge (SOC) of a flow battery system, flow battery based on a redundancy design of an SOC detection device, method and device for determining an actual capacity of the flow battery, and method and system for estimating an input-output characteristic of a flow battery alternating current side, the monitoring method comprising the following steps: determining SOCs of at least two pairs of different monitoring positions, any pair of monitoring positions being as followings: an inside of an anode electrolyte storage tank(2) and an inside of a cathode electrolyte storage tank(3), inside an anode electrolyte outlet pipeline(6) of a stack and inside a cathode electrolyte outlet pipeline(7) of the stack, or inside an anode electrolyte inlet pipeline(8) of the stack and inside a cathode electrolyte inlet pipeline(9) of the stack; and according to the SOCs respectively corresponding to each pair of monitoring positions, acquiring an SOC sum of a flow battery system. The method ensures acquiring an SOC monitoring result timely and accurately, thus facilitating an increase in a usage efficiency of a flow battery, extending the service life of the battery, and accurately managing a flow battery system.
