What are the models of lithium iron phosphate batteries?

Lithium iron phosphate battery model according to the cell packaging will have different ways of expression, cell main steel shell cylindrical, soft package aluminum plastic film and square aluminum shell these three, so the market can see the lithium iron phosphate battery model for the three cell model, of course, battery pack or battery pack battery model specifications are various.Here is a brief introduction to these three models of lithium iron phosphate batteries:

1, Steel shell cylindrical lithium iron phosphate battery model

Steel shell cylindrical lithium iron phosphate battery

The common battery model of steel shell cylindrical battery is A, AA, AAA, C, D, F, etc., while the most common and used model of steel shell iron phosphate battery is 18650 model, the common expression letter form: ICR18650,3.2V, 2800mAh;

18650 These numbers represent the external size of the battery: 18 the battery diameter 18.0mm, 650 the battery height 65.0mm.Due to the difference in the production process level and mode of the manufacturer, the size allows a certain error, which is ± 0.02mm.

2. Model of lithium iron phosphate battery with square aluminum shell

Square aluminum shell, lithium iron phosphate battery

There are not many battery manufacturers producing square aluminum shell lithium iron phosphate batteries, most of which are used in new energy vehicle batteries and energy storage battery packs. Battery models are expressed as 60Ah,3.2V,30-135-220;70Ah,3.2V, 30-135-222, which represent the same thickness of 30 m m, width of 135 m m, length of 220 m m and 222mm, voltage is 3.2V, and capacity of 60Ah and 70Ah respectively.

Square aluminum shell lithium iron phosphate battery model except for the size and capacity size can be different, its nominal voltage is 3.2V.

3. Model of soft aluminum plastic lithium iron phosphate battery

For soft pack lithium iron phosphate battery, more free on the appearance form, can be a triangle, square, round, arc can etc, so soft pack lithium iron phosphate battery model will be heavy and complicated, basic is different manufacturers have different model specifications, so the battery for custom cell battery.But its nominal voltage is also 3.2V, due to the material characteristics of the lithium iron phosphate battery itself.

So if you want to find a ready-made suitable cell model, it is generally difficult, but can be customized according to the requirements.

That is to say, soft package lithium iron phosphate battery model named expression is no industry unified standard requirements, basically is the manufacturer's own internal statement.
