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).
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. 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 filler includes a plurality of particles dispersed inside the polymer member. 5 . The battery module according to claim 1 , wherein 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 particles with different sizes. 7 . The battery module according to claim 1 , wherein the filler has an empty space formed therein. 8 . The battery module according to claim 1 , wherein the filler contains a fire-extinguishing material therein. 9 . The battery module according to claim 1 , wherein the filler contains a flame-retardant liquid therein. 10 . The battery module according to claim 1 , wherein the filler is configured such that the polymer member is partially inserted therein. 11 . The battery module according to claim 1 , wherein the filler includes a plurality of particles that respectively have an outer layer and a porous inner layer. 12 . A battery pack, comprising at least one battery module according to claim 1 . 13 . A vehicle, comprising at least one battery module according to claim 1 .
