20150280243 | MESH PLATE TYPE NICKEL SECONDARY BATTERY UNIT CELL AND NICKEL SECONDARY BATTERY STACK INCLUDING THE SAME - Disclosed are a mesh plate type nickel secondary battery unit cell and a nickel secondary battery stack including the same. The mesh plate type nickel secondary battery unit cell can secure a uniform gap between cathode and anode plates by withstanding expansion of a central portion of the cathode plate due to swelling caused by charge/discharge through a mesh plate structure of the cathode and anode plates and can prevent short circuit. The nickel secondary battery unit cell includes a cathode plate having a mesh plate structure; an anode plate having a mesh plate structure and separated from the cathode plate to face the cathode plate; and a separator interposed in a space between the cathode and anode plates. | 10-01-2015 |
20130230764 | METHOD OF MANUFACTURING HEADER FOR LITHIUM BATTERY USING POLYMER AND HEADER FOR LITHIUM BATTERY MANUFACTURED BY THE SAME - The present disclosure provides a method of simply manufacturing a header for lithium batteries using a polymer, and a header for lithium batteries manufactured by the same. The method includes securing a body having a hole inside dies and securing a cathode pin in the hole so as not to contact the body, filling the hole with polymer powder, and heating the dies to melt the polymer powder, followed by cooling and curing the melted polymer. | 09-05-2013 |
20130224543 | CATHODE FOR LITHIUM BATTERY WITH EXCELLENT OUTPUT PROPERTIES, METHOD OF MANUFACTURING THE CATHODE AND LITHIUM BATTERY USING THE SAME - The present disclosure provides a cathode for lithium batteries with a structure suited to high output properties, a method of manufacturing the same, and a lithium battery using the same. The cathode has a stack structure including a first cathode member, a separating member and a second cathode member stacked in sequence to have a pipe shape or a folded shape with spaced ends, wherein each of the first and second cathode members includes a current collector and a cathode active material formed on either side of the current collector. | 08-29-2013 |
