  • Patent number: 8709624
    Abstract: An energy storage device package is provided. The energy storage device package includes a bottom cover and a top cover connected to form a hollow chamber to accumulate an electrolyte, a first electrode and a second electrode formed on the top cover and which stretch from the top cover to the hollow chamber to contact the electrolyte, and a safety valve. The first electrode includes an opening and an exhaust channel that extends between the hollow chamber and the opening. When a gas pressure in the hollow chamber is smaller than or equal to a threshold value, the safety valve in the first electrode blocks the exhaust channel. When the gas pressure is larger than the threshold value, the gas pushes to open the safety valve and flows out from the hollow chamber through the exhaust channel and the opening.
