The lithium iron phosphate battery model has different expressions according to the outer packaging of the battery cell. The battery core is mainly divided into three types: steel shell cylindrical, soft-coated 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 battery cell models. Of course, the battery models and specifications after the cells are made into battery packs or battery packs are varied. Here is a brief introduction to the three types of lithium iron phosphate batteries:
1. Steel shell cylindrical lithium iron phosphate battery model
(Steel shell cylindrical lithium iron phosphate battery)
The common battery models of steel shell cylindrical batteries are A, AA, AAA, C, D, F, etc., while the most common and used specifications of steel shell lithium iron phosphate battery models are the 18650 model. Letters are commonly expressed on the surface of the battery: ICR18650, 3.2V, 2800mAh;
The numbers 18650 represent the external dimensions of the battery: 18 refers to the battery diameter of 18.0mm, and 650 refers to the battery height of 65.0mm. Due to the differences in the level of production technology and methods of manufacturers, 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 them are used in new energy vehicle batteries and energy storage battery packs. The battery models are mostly expressed in three dimensions, such as 60Ah, 3.2V. , 30-135-220; 70Ah, 3.2V, 30-135-222, they represent the same thickness of 30mm, the width of 135mm, length of 220mm and 222mm, voltage is 3.2V, capacity is 60Ah and 70Ah respectively Of two types of batteries.
In addition to the size and capacity of the square aluminum-shell lithium iron phosphate battery models can be different, the nominal voltage is 3.2V.
3. Model of soft-pack aluminum-plastic film lithium iron phosphate battery
(Soft pack aluminum-plastic film lithium iron phosphate battery)
For soft-packed lithium iron phosphate batteries, there is more freedom in appearance, which can be a triangular, square, round, arc, etc., so the soft-packed lithium iron phosphate battery models will be complicated and diverse Basically, different manufacturers have different models and specifications, so this type of battery is mostly customized battery. But its nominal voltage is also 3.2V, which is determined by the material characteristics of the lithium iron phosphate battery itself.
So if you want to find a ready-made suitable battery cell model, it is generally difficult, but you can customize it according to your needs.
That is to say, the naming expression of the soft-pack lithium iron phosphate battery model is not required by the industry's unified standard, and it is basically the manufacturer's own internal state.
