Storage device

A storage device comprising:

• an electrode body including a first electrode and a second electrode;
• an electrolyte including an organic solvent and a lithium salt;
• and
• a case accommodating the electrode body and the electrolyte,
• wherein
• the electrode body includes
• a first electrode tab group including a plurality of first electrode tabs that protrude from a first end portion, and
• a second electrode tab group including a plurality of second electrode tabs that protrude from a second end portion,
• the case includes
• a case body including
• a bottom wall,
• a pair of first side walls extending from the bottom wall and opposed to each other,
• a pair of second side walls extending from the bottom wall and opposed to each other, and
• an opening opposed to the bottom wall, and
• a sealing plate that seals the opening,
• the first electrode tab group is arranged at a side of one of the pair of second side walls inside the case,
• the second electrode tab group is arranged at a side of the other one of the pair of second side walls inside the case, and
• when the storage device is in a fully charged state,
• the storage device includes an excess electrolyte that is the electrolyte present between the case body and the electrode body in a state where a perpendicular direction to the bottom wall is a vertical direction, and
• a liquid level of the excess electrolyte is located closer to the sealing plate than a portion of the first electrode tab group that is closest to the bottom wall.
