Abstract
Provided are a current collector for a battery, including: a base material; adhesive layers positioned on the base material; and metal mesh layers positioned on the adhesive layers, in which the metal mesh layer includes a plurality of metal mesh patterns, and holes positioned between the metal mesh patterns, and a method of manufacturing the same. An active material is applied onto the metal mesh layer through the holes of the metal mesh layer, and thus a contact area of the metal mesh layer and the active material is increased, so that it is possible to restrict the active material from being deintercalated from the current collector and improve a cycle lifespan property of a battery.
