Provided are separators for use in an electrochemical cell comprising (a) an inorganic oxide and (b) an organic polymer, wherein the inorganic oxide comprises organic substituents. Also provided are electrochemical cells comprising such separators.

Separators for electrochemical cells

The present invention pertains to electrochemical cells which comprise (a) an anode; (b) a cathode; (c) a solid porous separator, such as a polyolefin, xerogel, or inorganic oxide separator; and (d) a nonaqueous electrolyte, wherein the separator comprises a porous membrane having a microporous coating comprising polymer particles which have not coalesced to form a continuous film. This microporous coating on the separator acts as a safety shutdown layer that rapidly increases the internal resistivity and shuts the cell down upon heating to an elevated temperature, such as 110&#xb0; C. Also provided are methods for increasing the safety of an electrochemical cell by utilizing such separators with a safety shutdown layer.

Safety shutdown separators

Provided are separators for use in an electrochemical cell comprising (a) an inorganic oxide and (b) an organic polymer, wherein the inorganic oxide comprises organic substituents. Preferably, the inorganic oxide comprises an hydrated aluminum oxide of the formula AlO.xHO, wherein x is less than 1.0, and wherein the hydrated aluminum oxide comprises organic substituents, preferably comprising a reaction product of a multifunctional monomer and/or organic carbonate with an aluminum oxide, such as pseudo-boehmite and an aluminum oxide. Also provided are electrochemical cells comprising such separators.

Provided are infrared reflective films comprising a substrate and at least one infrared reflective layer comprising an aminium radical cation compound in a crystalline state and an organic polymer, wherein the infrared reflective layer has a reflectance peak in the infrared region from 1250 nm to 1700 nm. Such infrared films are stable in their optical properties against degradation by light and moisture. Also provided are solar control window films, security markings, and other optical articles comprising such infrared reflective films. Further provided are methods for making such infrared reflective films.

Crystalline infrared reflective films

The present invention pertains to organic reflective layers comprising an organic radical cation compound, wherein the layer reflects in the infrared region. Preferably, the organic radical cation compound is a salt of an aminium radical cation. Provided are solar window films comprising such infrared reflective layers.
