Three minutes to understand the mainstream technology of power lithium ion battery -Lithium - Ion Battery Equipment
When the battery is charged, the lithium atoms on the positive pole are ionized and electrons (to be embedded). Lithium ions move to the negative electrode through electrolytes and obtain electronics. The electrons are restored to lithium atoms and embedded into the carbon layer micropore (penetrating).
When the battery is discharged, the lithium atoms embedded in the negative electrode carbon layer lost electrons (decentralized) into lithium ions, and then returned to the positive electrode (embedded) through the electrolyte.
The charging and discharge process of lithium -ion batteries is the process of continuously embedding and peeling between lithium ions between the positive and negative electrodes, and at the same time, it is accompanied by the equivalent electron embedded and stripping. The more lithium ions, the stronger the power charging capacity.
Classification
Due to the differences in positive data, lithium -ion batteries are importantly divided into lithium iron phosphate (LFP), nickel oxide lithium (LNO), manganese oxide lithium (LMO), cobalt oxide lithium (LCO), NCM lithium (NCM), nickel nickel nickel nickel nickel nickel Lithium (NCA).
Let's take a look at different types of lithium ion batteries on the market.
First of all, lithium cobalt oxides, as a pioneer of lithium ion batteries, can also be used as a power lithium -ion battery to test water. This is the first time that Tesla sports cars are used, but due to its low cycle life and safety, it is not suitable for it to be suitable As a power lithium ion battery. To make up for this defect, Tesla uses the best battery management system in the world to ensure the stability of the battery. Lithium cobalt oxides are now important participants in the 3C market.(Lithium - Ion Battery Equipment)
The second is lithium manganate, which was originally proposed by a battery company AESC. AESC is a joint venture between Nissan and NEC. The representative model of lithium manganate is Nissan Leaf. Due to its low price, medium energy density, average safety, it has so -called better induction functions. It is also because of this tepid nature that it is gradually replaced by new skills.
In addition, BYD's flagship products have stable performance, long life, and cost advantages, especially for plug-in hybrid vehicles, but their energy density is not high.
The end result is the ternary lithium ion battery, which is a new star with the highest energy density but relatively poor security. For the scope of the requirements of pure electric vehicles, its vision is wider, which is the mainstream direction of current power lithium -ion batteries.
Below is the Model3 announced by Tesla in July. It uses Panasonic's 21,700 trifuna (NCA) cylindrical battery.
In fact, in the power lithium -ion battery market, there are technical path competition between the three giants of my country, Japan and South Korea. In the so -called Romance of the Three Kingdoms, they are all recruiting and expanding their territory and fighting on the top of the mountain. Our next article will pay attention to this issue, so please continue to pay attention.
