How does a pressure relief valve work?
The valves also maintain the continuous pressure compensation required for normal battery operation. If a battery gets damaged, liquid electrolytes can escape into the battery housing as hot gases. These must then be released into the environment very rapidly and in a controlled process through a pressure relief valve.
