Abstract: Disclosed herein are an energy storage module formed by interconnecting a plurality of battery units, each of the plurality of battery units being formed by interconnecting two unit batteries and seating the interconnected unit batteries in a reception member, and a method for manufacturing the same. The energy storage module has conductive coating layers included in upper and lower plates contacting electrode tabs in a reception member to interconnect the conductive coating layers through a bus bar during manufacturing of a battery module rather than to interconnect the conductive coating layers by performing a welding method several times, thereby making it possible to more firmly couple the battery module. In addition, it is possible to flexibly form the battery module, as needed, and effectively radiate heat generated within the battery module during actual driving thereof.
