Abstract:
A paste-like mass that can be used in electrochemical elements, comprising a heterogeneous mixture of:(A) a matrix comprising at least one organic polymer, precursors thereof, or prepolymers thereof, and (B) an electrochemically activatable inorganic material that is not soluble in said matrix and that is in the form of a solid substance, wherein at least one of the following applies: a) said mixture comprises at least approximately 60 vol. % (B) and, if (B) is an electrode material, (B) is worked into said matrix (A) without the assistance of a solvent or swelling agent for said organic polymer, its precursors, or its prepolymers, b) said mixture comprises at least approximately 60 vol. % (B) and, if (B) is an electrode material, can be produced in that (B) is worked into a matrix (A) that also contains a plasticizer for said organic polymer, wherein said plasticizer is subsequently removed using a suitable solvent, and c) said mixture also contains: (C) at least one of a solid ion and mixed conductor that is different from (B) and that is present as a thin layer at least at the grain limits between (A) and (B).
