Abstract: A battery unit and a battery module including a stack of a plurality of the battery units. The battery unit includes: a battery cell including electrode terminals; and a case for housing the battery cell, wherein the case includes: a spacer that is disposed on facing portions of an edge of the case and protrudes in a thickness direction of the case, an inlet guide portion for guiding air for cooling the battery cell, and an outlet guide portion for guiding air to be discharged toward the electrode terminals.

Abstract: A battery pack that includes a battery cell having a positive and negative electrode terminal extending from a side of the battery cell. The positive and negative electrode terminal each have a non-exposed surface and an exposed surface. The battery pack also includes a case that includes a first case and a second case. The first case includes a first terminal guide unit to accommodate the positive electrode terminal with the non-exposed surface of the positive electrode terminal facing the first terminal guide. The second case includes a second terminal guide unit that accommodates the negative electrode terminal. The non-exposed surface of the negative electrode terminal faces the second terminal guide. The first case and the second case are coupled together with the battery cell positioned between the first case and the second case.
