Claim 0:
1. A high-voltage battery, comprising:
a battery housing having a cover,
a number of cell modules arranged within the battery housing, each cell module having a top that is spaced apart from the battery housing cover in a vertical direction of the housing via an installation gap inside the battery,
wherein, in the event of a thermal battery cell event in a battery cell of one of the cell modules, combustion gas is emitted and flows freely to an emergency degassing outlet of the battery housing via the installation gap inside the battery, and
a number of separate heat shield material portions arranged in the installation gap inside the battery between the cell module top and the housing cover, each of which heat shield material portions is associated with a cell module, wherein each heat shield material portion has at least one elastically resilient pressing element which is configured to push the heat shield material portion with a pressing force such that the heat shield material portion is in pressed contact with the top of the cell module,
wherein the at least one elastically resilient pressing element provides a reduced pressing surface comparative to the surface of the heat shield material portion.
