摘要： Systems and methods for charging and discharging a plurality of batteries are described herein. In some embodiments, a system includes a battery module, an energy storage system electrically coupled to the battery module, a power source, and a controller. The energy storage system is operable in a first operating state in which energy is transferred from the energy storage system to the battery module to charge the battery module, and a second operating state in which energy is transferred from the battery module to the energy storage system to discharge the battery module. The power source electrically coupled to the energy storage system and is configured to transfer energy from the power source to the energy storage system based on an amount of stored energy in the energy storage system. The controller is operably coupled to the battery module and is configured to monitor and control a charging state of the battery module.

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 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： A semi-solid electrode includes a first porous substrate and a second porous substrate stacked together to form a current collector, and a semi-solid electrode material embedded in the current collector. The semi-solid electrode material includes a suspension of an active material and a conductive material disposed in a non-aqueous liquid electrolyte. The porous substrates are at least partially disposed within the suspension such that the suspension substantially encapsulates the porous substrates. Each porous substrate in the current collector defines a pitch, and the two pitches of the two porous substrates in the current collector can be shifted with respect to each other by 30% to 70% of the pitch so as to reduce polarization effect.
