    Abstract: 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.

    Abstract: Embodiments described herein relate generally to electrochemical cells and electrodes with carbon-containing coatings. In some embodiments, an electrochemical cell can include an anode disposed on an anode current collector, a cathode disposed on a cathode current collector, and a separator disposed between the anode and the cathode. The separator has a first side adjacent to the cathode and a second side adjacent to the anode. The electrochemical cell further includes a coating layer disposed on the separator. The coating layer reduces dendrite formation in the electrochemical cell. In some embodiments, the coating layer can include hard carbon. In some embodiments, the coating layer can have a thickness between about 100 nm and about 20 μm. In some embodiments, the coating layer can be disposed on the first side of the separator.

    Abstract: Embodiments described herein relate to electrochemical cells with one or more electrodes coupled directly to a film material, and methods of making the same. In some embodiments, an electrochemical cell includes a first electrode material disposed on a first current collector, wherein the first current collector is coupled to a first non-conductive film. In some embodiments, a first tab is coupled to the first current collector. The electrochemical cell further includes a second electrode material capable of taking up or releasing ions during operation of the electrochemical cell. The second electrode material is coupled directly to a second non-conductive film. A second tab is electronically coupled to the second electrode material. A separator is disposed between the first electrode material and the second electrode material. In some embodiments, the second tab can be coupled directly to the second electrode material.
