Safety system for batteries
A battery, particularly a lithium-metal battery or a lithium-ion battery, having at least one galvanic cell surrounded by a cell housing. To increase the safety of the battery and to close up again a cell opened by a safety device or by a leakage, the inner chamber of the cell housing of the at least one cell includes a first chemical component, a chamber bordering on at least one section of the outer side of the housing including a second chemical component; a solid reaction product being developable by the chemical reaction of the first and second chemical components. The first component is containable in the electrolyte of the cell and the second component in a cooling and/or tempering arrangement. Also described is a cooling and/or tempering arrangement based on it, and an electrolyte, an electrolytic liquid, a safety system, a method and a mobile or stationary system.
