Abstract: The present invention relates to a microcurrent patch having a small battery and a circuit unit that are arranged on a substrate and are covered with a glue layer so as to be formed as one body on the substrate, and thus the present invention is easy to use, improves productivity, and has excellent flexibility, thereby facilitating attachment to a human body having many curves, and adjusting the amount of current flowing through the patch according to the linear width of the circuit unit or the number of holes in the glue layer.

Abstract: Disclosed is a lithium primary battery using a composite electrolyte, wherein, in order to maximize advantages of a lithium thionyl battery and a lithium sulfonyl battery, electrolytes of the two batteries are mixed to proceed two-stage discharging, thereby making it possible to check the battery usage.

Abstract: The protective circuit includes a voltage dividing circuit connected in parallel between a first electrode and a second electrode of the unit cell and including a first voltage dividing resistor and a second voltage dividing resistor; a first switching device connected to a junction between the first voltage dividing resistor and the second voltage dividing resistor; a second switching device connected between the junction and the third switching device; and a fourth switching device connected between the junction and the third switching device, wherein, when output voltage of the unit cell becomes equal to or lower than a first reference voltage, the fourth switching device and the first switching device are sequentially turned off, the second switching device is turned on, and the third switching device is turned off, so that voltage output through the first output terminal can be cut off.

Abstract: 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.

Abstract: 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.

Abstract: 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.
