Universal battery structure adopting lithium battery material

[0025] The standard AAA (flat head) battery is AAA battery, the standard height is 43.6±0.5mm, and the diameter is 10.1±0.2mm. Common uses include household remote controllers, small flashlights, electric toys, etc. It is one of the most common types of batteries. The AAA batteries that are common on the market now include dry batteries, alkaline manganese batteries, nickel-metal hydride batteries, etc., and the battery capacity is about 900 mAh.

[0026] With the standard AAA battery that the present invention makes, the inner diameter of battery is about 9.8mm, so the protective plate 5 inner diameter that selects is about 9.5mm. The thickness of the positive electrode of lithium iron phosphate is generally about 130mm, the thickness of the negative electrode is about 110mm, and the thickness of the diaphragm is about 20mm. Because the diaphragm has two layers, the thickness of the general negative electrode, positive electrode and diaphragm is estimated to be about 280mm. Acco
