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: Provided are a lithium primary battery in which a structure of an electrode closely related to output characteristics of the battery is improved to expand a reaction area, thus improving the output characteristics of the battery, and a method for manufacturing the lithium primary battery.

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: Disclosed herein are a lithium-sulfur battery and a method of manufacturing the same, whose cathode is manufactured by adding a binder mixture of two or more materials so as to develop pores within a cathode plate, so that does not exhibit shortcomings, including deterioration in cycle life characteristic, electrolyte leakage, deposition of lithium sulfide (Li2S) and a reduction in discharge capacity at high rate discharge. More specifically, disclosed herein is a cathode for lithium-sulfur batteries and a method of manufacturing the same, which is manufactured using a multicomponent binder mixture consisting of polytetrafluoroethylene and a thickener. Also, disclosed herein are a lithium-sulfur battery and a method of manufacturing the same, which is manufactured using the above cathode so as to develop pores within the electrode plate, so that the battery exhibits the extended cycle life, the non-leakage of electrolytes and the improved discharge capacity at high rate discharge.
