A separator for a lithium battery having (a) a porous polymeric layer, such as a polyethylene layer; and (b) a nanoporous inorganic particle/polymer layer on both sides of the polymeric layer, the nanoporous layer having an inorganic oxide and one or more polymers; the volume fraction of the polymers in the nanoporous layer is about 15% to about 50%, and the crystallite size of the inorganic oxide is 5 nm to 90 nm.

Multilayer nanoporous separator

Provided is a lithium battery, wherein the battery comprises an anode, a cathode, wherein the cathode comprises one or more transition metals, an electrolyte, and a porous separator interposed between the cathode and anode, wherein the separator comprises an anionic compound. Also provided are methods of manufacturing such batteries.

Nanoporous separators for batteries and related manufacturing methods

A separator for a lithium battery having (a) a porous polymeric layer, such as a polyethylene layer, and (b) a nanoporous inorganic particle/polymer layer on both sides of the polymeric layer, the nanoporous layer having an inorganic oxide and one or more polymers; the volume fraction of the polymers in the nanoporous layer is about 15% to about 50%, and the crystallite size of the inorganic oxide is 5 nm to 90 nm.

Nanoporous composite separators are disclosed for use in batteries and capacitors comprising a nanoporous inorganic material and an organic polymer material. The inorganic material may comprise AlO, AlO(OH) or boehmite, AlN, BN, SiN, ZnO, ZrO, SiO, or combinations thereof. The nanoporous composite separator may have a porosity of between 35-50%. The average pore size of the nanoporous composite separator may be between 10-90 nm. The separator may be formed by coating a substrate with a dispersion including the inorganic material, organic material, and a solvent. Once dried, the coating may be removed from the substrate, thus forming the nanoporous composite separator. A nanoporous composite separator may provide increased thermal conductivity and dimensional stability at temperatures above 200&#xb0; C. compared to polyolefin separators.

The present invention provides a protective backing sheet for photovoltaic modules. The backing sheet has a layer including fluoropolymer which is cured on a substrate, and the layer includes a hydrophobic silica. The amount of hydrophobic silica contained in the layer is within the range of 2.5 to 15.0% by weight, and preferably in the range of 7.5 to 12.5%. Also, the layer including fluoropolymer may further include a titanium dioxide.
