Abstract

Official abstract text for this publication.

A battery module may include a plurality of battery cells; a module case having an inner space therein and accommodating the plurality of battery cells in the inner space; a polymer member filled in at least a part of the inner space of the module case accommodating the plurality of battery cells; and a filler at least partially inside the polymer member and interposed in at least one space of a space between at least one of the plurality of battery cells and the module case and a space between the plurality of battery cells.

First claim

Opening claim text (preview).

What is claimed is: 1 . A battery module, comprising: a plurality of battery cells; a module case having an inner space therein and accommodating the plurality of battery cells in the inner space; a polymer member filled in at least a part of the inner space of the module case accommodating the plurality of battery cells; and a filler at least partially inside the polymer member and interposed in at least one space of a space between at least one of the plurality of battery cells and the module case and a space between the plurality of battery cells, wherein the filler includes a plurality of pellets, the filler includes a different material than the polymer member, wherein each of the pellets includes a flow hole penetrating from one end of each respective pellet to another end of the respective pellet, and wherein the polymer member is partially disposed in the flow hole of each respective pellet. 2 . The battery module according to claim 1 , wherein the polymer member includes a silicon resin. 3 . The battery module according to claim 1 , wherein the polymer member is cured after being filled in at least a part of the inner space of the module case. 4 . The battery module according to claim 1 , wherein the pellets of the filler are dispersed inside the polymer member. 5 . The battery module according to claim 1 , wherein the pellets of the filler includes a plastic material or a ceramic material. 6 . The battery module according to claim 1 , wherein the filler includes a plurality of pellets with different sizes. 7 . The battery module according to claim 1 , wherein the filler contains a fire-extinguishing material therein. 8 . The battery module according to claim 1 , wherein the filler contains a flame-retardant liquid therein. 9 . The battery module according to claim 1 , wherein the filler includes a plurality of pellets that respectively have an outer layer and a porous inner layer. 10 . A battery pack, comprising at least one battery module according to claim 1 . 11 . A vehicle, comprising at least one battery module according to claim 1 . 12 . The battery module according to claim 1 , wherein the pellets have a diameter between 0.5 mm and 1 mm.
