Abstract: The present disclosure relates to an anode comprising: an anode current collector; and a sheet layer disposed on the anode current collector and including a carbon nanotube sheet and metal particles, wherein the carbon nanotube sheet includes carbon nanotube strands having an average length of 1 m or more and 100 m or less. The present disclosure also relates to a method of manufacturing the anode. In the method, the carbon-nanotube sheet is immersed in an aqueous surfactant solution, for example, 0.001-0.1 M cetyltrimethylammonium bromide, vacuum-dried and then immersed in a silver-nanoparticle colloid solution (0.001-1/0M) that optionally contains a reducing agent such as sodium borohydride, followed by a second vacuum-drying step. The resulting anode exhibits improved electrical conductivity, uniform metal-particle distribution, high coulombic efficiency, and extended cycle life.

Abstract: Disclosed are an all-solid-state battery and a method of manufacturing the same, in which the all-solid-state battery includes a coating layer configured such that the surface of a porous network formed by intertwining fibrous carbon is coated with an inorganic electrolyte, thus improving charge/discharge efficiency and lifespan characteristics thereof.

Abstract: Disclosed herein is a no-welding type battery pack using one or more forced-inserting type rivets. A cap assembly includes a base plate mounted to an open upper end of a battery case, a protection circuit module (PCM) mounted on the base plate, and a top cap coupled to the upper end of the battery case while the top cap covers the PCM. The top cap is made of an insulative material. The electrical connection and the mechanical coupling between the PCM and the base plate are accomplished by one or more forced-inserting type rivets. The cap assembly is included the battery pack. The no-welding type battery pack using the one or more forced-inserting type rivets is manufactured without welding or soldering requiring an excessive amount of time and skilled technique during the electrical connection between the battery cell and the PCM. As a result, the assembly process of the battery pack is simplified, and therefore, the manufacturing time of the battery pack is reduced.
