Energy storage device package

An energy storage device package comprising:

• a bottom cover;
• a top cover connected to the bottom cover to form a hollow chamber to accumulate an electrolyte;
• a first electrode formed on the top cover and which stretches from the top cover to the hollow chamber to contact the electrolyte, the first electrode comprises an opening and an exhaust channel that extends between the hollow chamber and the opening;
• a second electrode formed on the top cover and which stretches from the top cover to the hollow chamber to contact the electrolyte;
• and
• a safety valve formed in the first electrode, wherein the safety valve comprises:
• a cover plate having a through hole, the cover plate is press-fitted to the inner edge of the opening;
• and
• an elastic body moveably disposed on the cover plate to block the through hole, wherein a cross-sectional area of the exhaust channel is smaller than or equal to a normal projection area of the cover plate;
• wherein when a gas pressure in the hollow chamber is smaller than or equal to a threshold value, the cover plate is disposed between the elastic body and the exhaust channel to cover the exhaust channel such that the safety valve in the first electrode blocks the exhaust channel;
• and
• when the gas pressure increases such that the gas pressure is larger than the threshold value, gas in the hollow chamber pushes to open the safety valve, thereby allowing part of the gas to flow out from the hollow chamber through the exhaust channel and the opening.
