[Solved] Salt and temperatures  



For what temperatures does the salt work? I guess there is some kind of max and min temperatures for charging and decharging.


What temperature that will work depends on which salt and what liquid that is used. The lowest temperature for charging can be around 50 degrees Celsius and the highest is around 500 degrees Celsius. The possible charging and discharging temperature depends on the delta T needed between the ends of the battery.
