Embodiment Construction

[0014] The present invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

[0015] Conventional CR2032 is a button-type lithium manganese battery with a diameter of 20mm and a height of 3.2mm. The battery is discharged according to the national standard GB8897, and the discharge time is 920h with a standard resistance of 15kΩ. The test data is shown in the following table:

[0016]

[0017] According to the discharge curve drawn in the above table, image 3 Shown.

[0018] The high-energy CR2032 battery of the present invention mainly improves the positive electrode of the battery, and correspondingly increases the weight of the negative electrode active material. The positive electrode distribution table is shown in Tab...
