Abstract: A battery pack includes a cell unit stack in which a plurality of cell units are stacked; a pack case accommodating the cell unit stack in an internal space; and a side wall located at an end of the cell unit stack in the internal space of the pack case and configured to support the pack case. The plurality of cell units are stacked in at least one direction within the cell unit stack, and the cell unit includes one or more pouch-type battery cells and a cell cover configured to at least partially surround the pouch-type battery cells.

Abstract: Provided is a battery pack and a vehicle including the same. The battery pack includes a plurality of pouch-type battery cells, a pack case having an inner space in which the plurality of pouch-type battery cells are accommodated, and a cell cover at least partially surrounding and supporting at least some of the plurality of pouch-type battery cells. The cell cover includes a first cover portion covering one side surface of at least one of the plurality of battery cells, a second cover portion covering the other side surface of at least one of the plurality of battery cells, and a third cover portion connecting the first cover portion to the second cover portion and covering an upper end portion of the at least one battery cell. A first venting hole through which gas or flame is discharged is formed in at least one portion of the third cover portion.

Abstract: A battery pack includes a plurality of pouch-type battery cells; a pack case accommodating the pouch-type battery cells in the internal space; and a cell cover. The cell cover includes two unit covers at least partially spaced apart, provided to at least partially surround at least some of the pouch-type battery cells among the plurality of pouch-type battery cells in the internal space of the pack case. The cell cover is configured to allow venting gas to be discharged into the separation space between the two unit covers, thereby ensuring excellent safety when a thermal event occurs. Moreover, the present application discloses a battery module and a vehicle including the same.

Abstract: A cell assembly according to the present disclosure includes a cell stack including one pouch-type battery cell or two or more pouch-type battery cells stacked; and a cell cover covering two side portions of the cell stack along a widthwise direction of the cell stack and a top portion of the cell stack, wherein the cell cover is configured to adjust a width of the cell cover according to a width of the cell stack.

Abstract: The present invention relates to a method for efficiently proliferating and differentiating natural killer cells (NK cells) from umbilical cord blood, more precisely a method for efficiently proliferating and differentiating natural killer cells from umbilical cord blood comprising the following steps: 1) preparing CD3 negative cells by eliminating CD3 positive T-cells from umbilical cord blood derived mononuclear cells; and 2) culturing the CD3 negative cells after treating various cytokines thereto. The present invention is advantageous in obtaining high purity NK cells in a short period of time by inducing NK cells from CD3 negative cells, compared with the conventional method inducing NK cells from haematopoietic stem cells, and in promoting NK cell proliferation and differentiation by treating different cytokines together, for example by the co-treatment of IL-15 and IL-21.
