| 20090142670 | ELECTROLYTIC SOLUTION AND LITHIUM BATTERY EMPLOYING THE SAME - Disclosed is an electrolytic solution including an organic solvent, a lithium salt, and an additive. The additive includes maleimide compound and vinylene carbonate. The maleimide compound can be maleimide, bismaleimide, polymaleimide, polybismaleimide, maleimide-bismaleimide copolymer, or combinations thereof. The lithium battery employing the described electrolytic solution has a higher capacity of confirmation, higher cycle efficiency, and longer operational lifespan. | 06-04-2009 |
| 20100022716 | METHOD AND FORMULA FOR FORMING HYPER-BRANCHED POLYMER - The invention provides hyper-branched polymer manufactured by adding a bismaleimide and a barbituric acid into a Brönsted base solution and reacting the mixture at 20 to 100° C. The formation may further include maleimide monomer and/or multi-maleimide monomer to modify the hyper-branched polymer properties. In addition, the barbituric acid is added to the reaction in a batch not initially charged with other reactants in a one-pot. | 01-28-2010 |
| 20100130625 | PROTON EXCHANGE MEMBRANE AND METHOD FOR MANUFACTURING THE SAME - A proton exchange membrane and method for formation the same is disclosed. When forming the proton exchange membrane, first, a bismaleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluorethylene copolymer (Nafion) aqueous solution is replaced with dimethyl acetamide (DMAc). 10 to 15 parts by weight of the hyper-branched polymer is added to 90 to 85 parts by weight of the Nafion in the DMAc solution, stood and heated to 50° C. for inter-penetration of the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent to complete formation of the proton exchange membrane. | 05-27-2010 |
| 20100143767 | BINDER COMPOSITIONS AND MEMBRANE ELECTRODE ASSEMBLIES EMPLOYING THE SAME - Binder composites for membrane electrode assemblies and membrane electrode assemblies employing the same are provided. The binder composition includes a solvent, a hyper-branched polymer and a polymer with high ion conductivity, wherein the hyper-branched polymer and the polymer with high conductivity of hydronium are distributed uniformly over the solvent, and the hyper-branched polymer has a DB (degree of branching) of more than 0.5. | 06-10-2010 |
| 20100167101 | PROTON EXCHANGE MEMBRANE COMPOSITION - Proton exchange membrane compositions having high proton conductivity are provided. The proton exchange membrane composition includes a hyper-branched polymer, wherein the hyper-branched polymer has a DB (degree of branching) of more than 0.5. A polymer with high ion conductivity is distributed uniformly over the hyper-branched polymer, wherein the hyper-branched polymer has a weight ratio equal to or more than 5 wt %, based on the solid content of the proton exchange membrane composition. | 07-01-2010 |
| 20100167102 | INTER-PENETRATED PROTON EXCHANGE MEMBRANE, METHOD FOR MANUFACTURING THE SAME, AND PROTON EXCHANGE MEMBRANE FUEL CELL UTILIZING THE SAME - The disclosed forms a proton exchange membrane. First, multi-maleimide and barbituric acid are copolymerized to form a hyper-branched polymer. Next, the solvent of the sulfonated tetrafluorethylene copolymer (Nafion) aqueous solution is replaced from water with dimethyl acetamide (DMAc). 10 to 20 parts by weight of the hyper-branched polymer is added to the 90 to 80 parts by weight of the Nafion in a DMAc solution, stood and heated to 50° C. to inter-penetrate the hyper-branched polymer and the Nafion. The heated solution is coated on a substrate, baked, and pre-treated to remove residue solvent for completing an inter-penetrated proton exchange membrane. | 07-01-2010 |
| 20100167129 | METHOD FOR MODIFYING CATHODE MATERIAL AND LITHIUM BATTERY EMPLOYING THE CATHODE MATERIAL - The invention provides a lithium battery, including: a cathode plate and an anode plate; a separator disposed between the cathode plate and the anode plate to define a reservoir region; and an electrolyte filled in the reservoir region. A thermal protective film is provided to cover a material of the cathode plate or the anode plate. When a battery temperature rises over an onset temperature of the thermal protective film, it undergoes a crosslinking reaction to inhibit thermal runaway. A method for fabricating the lithium ion battery is also provided. | 07-01-2010 |
| 20110117444 | Electrolytic Solution and Lithium Battery Employing the Same - Disclosed is an electrolytic solution including an organic solvent, a lithium salt, and an additive.
