It is the object of the invention to provide solid electrolyte for use in lithium-air batteries or lithium-water batteries, with the solid electrolyte having sufficient strength, good conductivity for lithium ions, imperviousness for gas and water resistance and being inexpensive in manufacture. The solid-state electrolyte in accordance with the invention has an open-pore ceramic carrier substrate. In this respect, at least one layer which is conductive for lithium ions, which has an electrical conductivity of at least 10−5 Scm−1 and which is gas-impervious is formed on the surface facing the cathode. In this respect, the carrier substrate has greater mechanical strength and a larger layer thickness than the at least one layer.

摘要: An electrolyte composition has a fluoroalkylsulfonyl salt and water. The water is present, relative to the fluoroalkylsulfonyl salt, at a molar ratio within a range of 0.1:1 to 10:1, inclusive. This creates a “water-in-salt” in which individual water molecules are surrounded by salt rather than vice versa. Water contained in this environment is electrochemically stabilized relative to a bulk water. The electrolyte also has an organic carbonate present, relative to the fluoroalkylsulfonyl salt, at a molar ratio within a range of 0.1:1 to 50:1, inclusive. It has been discovered that inclusion of the organic carbonate further increases the electrochemical stability of the water within the “in-salt” environment.
