Abstract: A composition for the immediate stopping of a free-radical polymerization comprises a) an inhibitor for the free-radical polymerization selected from among phenothiazines, b) an aprotic solvent and c) an ionic liquid. It serves to stabilize free-radically polymerizable monomers against free-radical polymerization. For the immediate stopping of free-radical polymerizations, the composition is added to a free-radically polymerizing system.

Abstract: Spiro ammonium salts as an additive for electrolytes in electric current producing cells, in particular electric current producing cells comprising a Li-based anode, are provided. In some embodiments, the electric current producing cell comprises a cathode, a Li-based anode, and at least one electrolyte wherein the electrolyte contains at least one spiro ammonium salt.

Abstract: Li-based anodes for use in an electric current producing cells having long life time and high capacity are provided. In certain embodiments, the Li-based anode comprises at least one anode active Li-containing compound and a composition comprising at least one polymer, at least one ionic liquid, and optionally at least one lithium salt. The composition may be located between the at least one Li-containing compound and the catholyte used in the electric current producing cell. In some embodiments, the at least one polymer may be incompatible with the catholyte. This configuration of components may lead to separation between the lithium active material of the anode and the catholyte. Processes for preparing the Li-based anode and to electric current producing cells comprising such an anode are also provided.
