A battery pack () includes a housing () and an array of electrochemical cells () disposed in the housing (). The housing () includes a container () and a lid () that closes an open end of the container (). The container () has a base (), a sidewall () that surrounds the base (), and a spring plate () disposed inside the sidewall () between the cells () and the sidewall (). The spring plate () is free standing within the container () and applies a spring force to the cell array that restrains the cells () along an axis normal to the surface of the spring plates (). The lid () includes inwardly-protruding pins () that further restrain the cells () within the housing ().

Battery pack including cell restraint

A battery (), in particular a lithium-ion battery, having: a plurality of battery cells (), which are assembled to form a cell stack and are received in a housing (), wherein the battery cells () are bonded to the base () of the cell housing () by a heat conductive bonding material (TIM), a plurality of spacer elements (), wherein a spacer element () of the plurality of spacer elements () is arranged in each case between two adjacent battery cells () of the plurality of battery cells (), two end plates (), which delimit the cell stack at the ends, wherein the end plates () are connected by at least one tensioning band (), wherein the at least one tensioning band () at least partially surrounds the cell stack circumferentially. To this end, it is provided according to the invention that the at least one tensioning band () is bonded to the side walls of the battery cell () by a band bonding material.
