Abstract
In a non-aqueous electrochemical battery, there are formed a plurality of grooves with thinned bottom portion on the bottom of the battery container. The grooves are intersected at least at one point and the bottom of the grooves are made flat so that the explosion-proof arrangement is operable for a desired inner pressure of the battery.
