Abstract
An apparatus and method for detecting a foreign material within a pouch type battery by performing a light scattering method on a surface of a battery case are provided. The apparatus for detecting a foreign material within a pouch type battery includes: a light source irradiating linear light to a surface of a battery case at a pre-set incident angle; a sensor unit sensing light reflected from the battery case; and a foreign material detection unit detecting the presence or absence of a foreign material and the position of the foreign material within a battery through the reflected light sensed by the sensing unit. A foreign material within a battery can to be quickly and accurately detected.
