Liquid ejection apparatus and liquid storage device

A liquid ejection apparatus comprising:

• a storage container configured to store a liquid having conductivity;
• a first electrode housed in a first liquid chamber of the storage container;
• a second electrode housed in a second liquid chamber of the storage container;
• a partition wall which is housed in the storage container, and is configured to partition the first liquid chamber and the second liquid chamber;
• a detection unit which is electrically coupled to the first electrode and the second electrode, and is configured to output a detection signal corresponding to an electrical signal from one of the first electrode and the second electrode;
• and
• an identification unit configured to identify a remaining amount of the liquid stored in the storage container based on the detection signal, wherein
• a first opening communicating the first liquid chamber and the second liquid chamber with each other is formed below the partition wall,
• a second opening communicating the first liquid chamber and the second liquid chamber with each other is formed above the partition wall, and
• when the liquid stored in the storage container is present in the first opening and the second opening,
• the first electrode and the second electrode are in contact with the liquid stored in the storage container.
