What does the stock concept pvdf mean?

PVDF concept stocks are also lithium battery concept stocks. Benefiting from the rapid development of the new energy automobile industry, the demand for lithium batteries has exploded rapidly. Since more than 90% of the cathode binders in lithium battery auxiliary materials use PVDF, the overall PVDF market is in shortage, and its related stocks are called PVDF concept stocks. Four important basics of stock market investing!

1. Learn to find the root cause

There are two types of A-shares, one is called capital market and the other is called political market. No matter what policies are issued by the market, the corresponding sectors and concepts will increase accordingly, the so-called "policy market"; which sectors are managed by the major market funds and which sectors are rising, this is the “capital market”; . So muchIf you know how to follow these two principles, you will be able to get there more easily. In fact, it means knowing market policies. In today's information age, simply scroll through market analyzes to see at a glance which sectors are supported by current policies and which market topics are hot. There is no increase without reason, and there is no decrease without reason. Many friends buy stocks to see the trend of stocks, but the trend is only an external manifestation. What we need to know is why it is increasing and why it is increasing. falls.

2. We must learn long-term analysis

The so-called long-term analysis is actually understanding the direction of policy development. For example, flammable ice some time ago, like today's new energy industry, are all future trends developed. The reason for success is that wecan follow the news timely and have high sensitivity, long-term understanding and research of the impact of policies on the stock market. But some friends also want to ask, why is it possible to capture stocks with such precision?

3. Use the right tools

Yes, how can it be possible to follow the trend accurately every time? ! In fact, it is with the help of trading tools that tools have powerful and complex data analysis, which is more accurate than human analysis. In addition, current tools have functions such as “buying and selling advice”. find good deeds. If you don't know how to find stocks with strong momentum, you can simply use tools to read the tips. Friends with a little experience can be more precise using tools!

4. Read and learn more about stocks

Read moreus news in the newspapers! Read more news in the newspapers! Read more news in the newspapers! Say important things three times. Paying more attention to newspapers and news is the direct route, as every market movement and policy news will make the news. As you read more and observe more, you will gradually gain sensitivity. future. Some friends said that they were very busy at work and had no time to read. What should I do ? I think old friends all know this. As long as you follow your circle of friends, you basically don't need to read newspaper information. The content and opinions are for reference purposes only and do not constitute investment advice. at your own risk. The stock market is risky, so be careful when entering the market.

Lithium iron phosphate battery: what are the componentsof the raw material of the positive electrode? What are the raw material components of negative electrodes?

The ingredients of the positive and negative electrodes of lithium batteries used in solar street lights mainly include the following materials.

Cathode ingredients:

1. Cathode active materials: Commonly used.Positive active materials include lithium manganate (LiMn2O4), lithium cobalt oxide (LiCoO2), and lithium iron phosphate (LiFePO4). Among them, lithium iron phosphate is currently the most widely used cathode material because of its high safety, good service life and high energy density.

2. Binders: Commonly used binders include polymers, such as polyacrylate (PAA) and polyvinyl ester (PEA). The function of the binder is to bind together the positive active material and the conductive agent to former a solid positive structure.

3. Conductive agent: Commonly used conductive agents include carbon black and conductive polymers. The function of the conductive agent is to improve the conductive performance of the positive electrode and promote the conduction of electrons.

Anode ingredients:

1. Negative active material: The commonly used negative active material is graphite. Graphite has good service life and high energy density, and is currently the most widely used anode material.

2. Binder: Polymer is also used as a binder to bind the negative active material and the conductive agent together.

3. Conductive agent: Commonly used conductive agents include carbon black and conductive polymers. The function of the conductive agent is to improve the conductive performance of the negative electrode and promote the conduction of electrons.

In addition to the above ingredients, lithium batteries also include an electrolyte and a separator. The electrolyte generally consists of lithium salts and organic solvents to ensure the transport of lithium ions. The separator is used to isolate the positive and negative electrodes to prevent short circuits.

In short, the ingredients of positive electrodes of lithium batteries used in solar street lights mainly include positive active materials, binders and conductive agents, and the ingredients of negative electrodes mainly include negative active materials , binders and conductive agents. The selection and combination of these ingredients can be tailored to specific application needs and performance requirements.

Cathode material: lithium iron phosphate, PVDF, conductive carbon black, NMP (solvent). Materialanode: general graphite, PVDF, conductive carbon black, NMP (solvent). Of course, water-based adhesives are also available. Lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate (LiFePO4) as the positive electrode material and carbon as the negative electrode material. The nominal cell voltage is 3.2 V and the charge cut-off voltage is 3.6. V~3.65 V.

Characteristics

In the crystal structure of LiFePO4, the oxygen atoms are arranged in a tight hexagonal arrangement. The PO43 tetrahedron and the FeO6 octahedron form the spatial skeleton of the crystal. Li and Fe occupy the octahedral voids, while P occupies the tetrahedral voids, Fe occupies the corner-sharing positions of the octahedron, and Li occupies the edge-sharing positions of the octahedron. octahedron.

The FeO6 octahedra are connected to each other on the bc plane of the crystal, and theLiO6 octahedral structures in the b-axis direction are connected to each other to form a chain structure. 1 FeO6 octahedron shares edges with 2 LiO6 octahedrons and 1 PO43 tetrahedron.
