| 20120328961 | AQEUOUS ELECTROLYTE COMPOSITION AND SEALED-TYPE PRIMARY FILM BATTERY INCLUDING ELECTROLYTE LAYER FORMED OF THE AQUEOUS ELECTROLYTE COMPOSITION - Provided are an aqueous electrolyte composition including hydrophilic microparticles and a sealed-type primary film battery including an electrolyte layer formed of the aqueous electrolyte composition. In the sealed-type primary film battery, a separation film is interposed between a positive electrode and a negative electrode, and has a plurality of through-holes. A non-flowable electrolyte layer interposed between the positive electrode and the negative electrode includes first and second electrolyte layers extending parallel to the positive electrode and the negative electrode, and a plurality of third electrolyte layers filled in the through-holes of the separation film so as to be integrally connected to the first electrolyte layer and the second electrolyte layer. Due to the third electrolyte layers filled in the through-holes of the separation film, an ion transfer path in the electrolyte layer is shortened. The hydrophilic microparticles are dispersed in the electrolyte layer so as to prevent moisture evaporation. | 12-27-2012 |
| 20130122379 | LITHIUM-ION BATTERY AND METHOD FOR FABRICATING THE SAME - A lithium-ion battery and a method for fabricating the same are provided. The lithium-ion battery includes an anode, a cathode, a separator, and an electrolyte solution. The cathode is disposed opposite to the anode. The separator is disposed between the anode and the cathode, where an accommodating region is defined by the anode, the cathode and the separator. The electrolyte solution disposed within the accommodating region includes an organic solvent, a lithium salt and an additive. The additive includes a sulfonyl-containing species, and the content thereof is 0.1 to 5 wt % based on the total weight of the electrolyte solution. The whole-cell potential of the lithium-ion battery is 4.5 V or above. In the lithium-ion battery and the method for fabricating the same of the invention, the sulfonyl-containing species serves as the additive, so that the battery is capable of being operated under a condition of high-voltage charge and discharge. | 05-16-2013 |
