Abstract: A lithium ion rechargeable battery comprises: a negative electrode adapted to give up electrons during discharge, a positive electrode adapted to gain electrons during discharge, a microporous separator sandwiched between said positive electrode and said negative electrode, an organic electrolyte being contained within said separator and being in electrochemical communication with said positive electrode and said negative electrode, and an oxidative barrier interposed between said separator and said positive electrode, and thereby preventing oxidation of said separator.

Abstract: A battery separator for a lithium-ion secondary battery is a microporous membrane with an adjuvant. The microporous membrane is made of a thermoplastic. The adjuvant, in an effective amount, is mixed into the separator or coated thereon. The adjuvant is a material adapted to reduce or eliminate energy concentrations around the separator. The energy concentration is sufficient to initiate a reaction of the components of the lithium ion secondary battery.

Abstract: The instant invention is directed to a secondary lithium battery. The battery includes a negative electrode, a positive electrode, a separator sandwiched between the electrodes, an electrolyte impregnating the separator and being in a fluid communication with the electrodes, and a metal package adapted for containing the electrodes, the separator, and the electrolyte. One of the electrodes is in thermal contact with the package.

Abstract: A new PEM and fuel cell using that PEM are disclosed. The proton electrolyte membrane (PEM) comprises a polymer matrix and an ionically conductive ceramic material adapted to create a superconductive interface, the ceramic material being uniformly dispersed throughout the matrix. The polymer matrix is selected from the group consisting of proton exchange polymers, non-proton exchange polymers, and combinations thereof. The material is selected from the group consisting of beta alumina oxides, SnO2(nH2O) , fumed silica, SiO2, fumed Al2O3, H4SiW12O2(28H2O), tin mordenite/SnO2 composite, zirconium phosphate-phosphate/silica composite.

Abstract: The instant invention is directed to a separator for a high energy rechargeable lithium battery and the corresponding battery. The separator includes a ceramic composite layer and a polymeric microporous layer. The ceramic layers includes a mixture of inorganic particles and a matrix material. The ceramic layer is adapted, at least, to block dendrite growth and to prevent electronic shorting. The polymeric layer is adapted, at least, to block ionic flow between the anode and the cathode in the event of thermal runaway.
