Patent number: 9761887Abstract: An energy storage apparatus having a housing, a plurality of battery cells, a temperature-control system with a liquid temperature-control medium for cooling and/or heating the battery cells in the housing. An absorbent element is arranged spatially between the battery cells and the housing such that any temperature-control medium escaping from the temperature-control system is absorbed by the absorbent element. The absorbent element is separated from the battery cells by an electrically insulating layer, the electrically insulating layer being impermeable to the temperature-control medium.Type: GrantFiled: August 23, 2013Date of Patent: September 12, 2017Assignee: Samsung SDI Co., Ltd.Inventors: Peter Dämon, Stefan Roepke, Mario Steiner, Thomas Trathnigg
