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 non-aqueous 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/cm2 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: Provided is a battery cell stack in which the electrical resistance between a current collector plate and an end bipolar plate is unlikely to increase when charging and discharging are repeated. A battery cell stack includes a current collector plate electrically connected to each of a pair of end bipolar plates located at both ends in the stacking direction. In the battery cell stack, two members in contact with each other between the current collector plate and the end bipolar plate are made of materials such that, when an accelerated test satisfying the following conditions 1 to 3 is performed, the electrical resistance value between the current collector plate and the end bipolar plate after the accelerated test is 1.05 times or less the electrical resistance value between the current collector plate and the end bipolar plate before the accelerated test: Condition 1 is that a cycle includes applying pressure over one minute to achieve a predetermined pressure, maintaining the predetermined pressure for one minute, and bringing the predetermined pressure back to the atmospheric pressure over one minute; Condition 2 is that the predetermined pressure is set to be the atmospheric pressure +0.1 MPa; and Condition 3 is that the number of cycles is set to 18.

    摘要: An electrolyte conveyance device for flow battery includes a first permanent magnet direct current (PMDC) motor, a second PMDC motor, a power-output shaft, a first screw rod conveyance unit, and a second screw rod conveyance unit. The power-output shaft is a common power-output shaft of the first and second PMDC motors for driving the first and second screw rod conveyance units to operate at the same time, so as to convey a positive and a negative electrolyte, respectively, from positive and negative electrolyte tanks to a battery cell of the flow battery. The first and second PMDC motors serve as filters on a charging and a discharging circuit of the flow battery, and are driven by the electrical energy of removed surges to operate for conveying the electrolytes without consuming the electrical energy stored in the flow battery.
