How many kinds can lithium batteries be divided into?

There are several kinds of lithium battery, lithium battery can be divided into how many kinds? When we talk about the knowledge of batteries, we should first introduce the classification of lithium batteries according to the electrode material and product appearance. Lithium battery classification: There are two commonly used classification methods on the market: by electrode material classification and by product appearance classification.

1. According to the classification of electrode materials

Battery cathode materials: lithium iron phosphate battery (LFP), lithium cobalt oxide battery (LCO), Lithium manganese oxide battery (LMO), (binary battery: Lithium nickel-manganese oxide lithium nickel-cobalt oxide), (ternary battery: Lithium nickel-cobalt Manganese oxide battery (NCM), lithium nickel-cobalt aluminate battery (NCA))

Anode materials: lithium titanate battery (LTO), graphene battery, carbon nanofiber battery.

The key to the graphene concept in the market is the use of graphene-based rechargeable batteries, where graphene-based materials or graphene-based coatings are added to the membranes in polar TV dramas. Lithium-magnesium-based rechargeable battery sales market will have no foundation.

2. Classify products according to their appearance

Divided into: cylinder, soft bag and square

Cylindrical and square outer packages are usually made of steel or aluminum. The outer packing of soft bag is aluminum plastic film. The soft bag is also square. The aluminum-plastic packaging used in the market is called soft bag. Some people call soft bag batteries lithium polymer.

For lithium-ion battery models, it is a common 5-bit specification. The first two digits are the middle number of the direct number and the rechargeable battery. It is the enterprise mm. For example, 186 lithium ions are 58 millimeters wide and 65 millimeters high.

3. According to the different electrolyte materials, lithium batteries are divided into liquid lithium batteries (LIB) and polymer lithium batteries (PLB).

Liquid lithium batteries are used for liquid electrolytes (mainly for rechargeable batteries). It is replaced by a lithium polymer solid polymer electrolyte solution, which may be dry or gelatinous. Currently, most are polymer electrolyte solutions. For solid state batteries, the exact meaning is that both the liquid level and the electrolyte are solid.

4. Classify batteries according to their performance

Output rechargeable battery and rechargeable battery. Dynamic rechargeable battery has the characteristic of high energy relative density, the key is high energy discharge. The output of lithium-ion power has increased with the advent of hybrid cars. It requires rechargeable batteries to store high kinetic energy and can be used in pure electric vehicles over a certain distance. Also has good output power characteristics, in low power mode into the hybrid mode.

This is not difficult to understand, similar to marathon runners, the type of kinetic energy with physical ability is the charge and discharge characteristics of regulating large capacity and large current; And then the type of power output is the sprinter, who has a lot of fighting power, but a lot of physical strength, or a little capacity to run very close.

These are the four categories of lithium batteries. There are four major types of batteries. Once you know the species, you can learn a lot about lithium batteries.
