Abstract
The present disclosure provides an electrode assembly including a unit cell stack having n unit cells stacked with a separation film interposed therebetween and at least one reinforcing member formed from metal that integrally covers at least one of the upper and lower surfaces and at least one side surface of the unit cell stack. In particular, n is an odd number excluding 1. Additionally, in each unit cell, one or more cathodes and one or more anodes are stacked with a separator interposed therebetween. Accordingly, the unit cells are protected against external impacts.
