摘要： The present disclosure relates to a thick film electrode and a method for manufacturing the same. Since the thick film electrode uses a photocurable monomer as a processing solvent, it requires no separate drying step and may have a sufficiently large thickness without physical cracking. In addition, since the thick film electrode uses a nonwoven web-type substrate having a carbon body applied to the surface of a conductive polymer, it may have higher ion conductivity and areal capacity. Further, a semi solid-state battery including the thick film electrode may have excellent energy density.

摘要： Systems and methods for anisotropic expansion of silicon-dominant anodes may include a cathode, an electrolyte, and an anode, where the anode may include a current collector and an active material on the current collector. An expansion of the anode during operation may be configured by a roughness and/or thickness of the current collector, a metal used for the current collector, and/or a lamination process that adheres the active material to the current collector. The expansion of the anode may be more anisotropic for thicker current collectors. A thicker current collector may be 10 μm thick or greater. The expansion of the anode may be more anisotropic for more rigid materials used for the current collector. A more rigid current collector may include nickel and a less rigid current collector may include copper. The expansion of the anode may be more anisotropic for a rougher surface current collector.
