FIELD: electrical engineering; electrochemical power supplies.
SUBSTANCE: proposed electrochemical cell has two types of separators of different destruction energy and electrode assembly of several electrode layers; most external electrode layer of assembly has cathode non-covered with active material, anode non-covered with active material, and separator (second separator) disposed between these cathode and anode and characterized in relatively low destruction energy compared with that of separators (second separator) in other electrode layers.
EFFECT: enhanced safety of device.
