摘要: Provided are a nano-sized thin sheet-like pseudoboehmite and a method of producing the same. The method of producing a sheet-like pseudoboehmite is performed by a one-pot method, unlike the conventional method of performing the reaction first in a basic solution, and then performing redispersion in an acidic solution, thereby simplifying the production process, and thus, may be useful in the production industry of a separator for a secondary battery, and the like.

摘要: In a nonaqueous electrolyte secondary battery, a separator includes a substrate, a first filler layer containing phosphate salt particles, and a second filler layer interposed between the substrate and the first filler layer and containing inorganic particles. The separator is disposed between a positive electrode and a negative electrode in such a manner that the first filler layer and the second filler layer are directed to the positive electrode side. Further, a resin layer is disposed between the positive electrode and the first filler layer.

摘要: Provided are printed electrochemical cells, which utilize zinc salts for ionic transfer, and methods of fabricating such cells. In some examples, a printed electrochemical cell comprises a positive electrode with a positive current collector having a two-dimensional shape and comprising an electrolyte-facing surface formed by the graphite. For example, the positive current collector may be a graphite foil or an aluminum foil with a graphite coating. The cell also comprises electrolyte comprising an electrolyte salt and an electrolyte solvent. For example, the electrolyte salt comprises a zinc salt with a concentration of at least 30% by weight in the electrolyte. The cell is fabricated by printing a positive active material layer over the positive current collector, printing one or more electrolyte layers on various cell components, and laminating a separator layer between the positive and negative electrodes while soaking the separator layer with the electrolyte.
