Introduction of Three Lithium Iron Phosphate Battery Models

The model of lithium iron phosphate battery will have different expressions according to the outer packaging of the battery cell. The battery cell is mainly divided into three types: cylindrical steel shell, soft aluminum-plastic film and square aluminum shell. Therefore, the lithium iron phosphate that can be seen on the market Most of the battery models are these three types of batteries.

Of course, the battery models and specifications after the batteries are made into battery packs or battery packs are varied. Here is a brief introduction to these three lithium iron phosphate battery models:

The common battery models of steel shell cylindrical batteries are A, AA, AAA, C, D, F, etc., while the most common and used specification of the steel shell lithium iron phosphate battery is the 18650 model, which is commonly expressed in the form of letters on the surface of the battery: ICR18650, 3.2V, 2800mAh; the numbers 18650 represent the external size of the battery: 18 means the diameter of the battery is 18.0mm, and 650 means the height of the battery is 65.0mm. Due to the difference in the production process level and method of the manufacturer, a certain error is allowed in the size, and the error is ±0.02mm.

There are not many battery manufacturers that manufacture square aluminum shell lithium iron phosphate batteries, and most of them are used in new energy vehicle batteries and energy storage battery packs. The battery models are mostly expressed in terms of thickness, width and length, such as 60Ah, 3.2V , 30-135-220; 70Ah, 3.2V, 30-135-222, they represent the same thickness is 30mm, width 135mm, length is 220mm and 222mm, voltage is 3.2V, capacity is 60Ah and 70Ah Two types of batteries.

Except for the size and capacity of the square aluminum shell lithium iron phosphate battery, the nominal voltage is 3.2V.

For the soft-pack lithium iron phosphate battery, it is more free in the form of appearance, which can be triangular, square, round, curved, etc., so the soft-pack lithium iron phosphate battery model will be complicated and diverse. , Basically, different manufacturers have different models and specifications, so most of these batteries are custom-made batteries. But its nominal voltage is also 3.2V, which is determined by the material characteristics of the lithium iron phosphate battery itself.

Therefore, if you want to find a ready-made suitable battery model, it is generally difficult, but you can customize it according to your needs. That is to say, there is no unified industry standard requirement for the model naming expression of the soft-pack lithium iron phosphate battery, and it is basically the manufacturer’s own default statement.
