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.
