Graphite Anode Material - China
price: 3.00 Dollar US$
The negative electrode is a main component of the lithium battery.
It is made by mixing a negative electrode active material, a binder and an additive into a paste and uniformly coating it on both sides of the copper foil, and drying and rolling.
The negative electrode material we are talking about mainly refers to the negative electrode active material.
Graphite anode material
Graphite anode material
It is well known that the energy density of a lithium ion battery depends on its specific capacity and operating voltage, wherein the specific capacity is determined by the specific capacity of the positive electrode and the specific capacity of the negative electrode (see the following equation), and the operating voltage is the difference between the positive voltage and the negative voltage ( Also known as deintercalating lithium voltage).
It can be seen that the specific capacity of the negative electrode (the bigger the better) and the operating voltage (the lower the better) directly determine the energy density of the lithium battery, and its importance is self-evident.
The artificial graphite anode is processed from carbon material.
It is made by graphitizing the soft carbon material which is easy to be graphitized by high temperature above 2 500 °C.
At this time, the secondary particles inside the carbon material are arranged in a random manner, and there are a large number of pore structures, which facilitates the penetration of the electrolyte and the deintercalation of the lithium ion ruthenium anode, so the artificial graphite anode material can increase and enhance the rapid charge and discharge speed and frequency of the lithium ion battery.
Artificial graphite has advantages such as long-circulation, high-temperature storage, high-magnification etc.
which natural graphite don’t have.
The anode materials used in domestic lithium batteries for new energy vehicles are mostly artificial graphite anodes.
In 2016, the market share of artificial graphite in anode materials exceeded 60%.
In the next few years, the vigorous development of the new energy vehicle power battery market is the main driving force for the demand for artificial graphite and the sharp increase in production.
Artificial graphite is a product in which coke-based raw materials are converted into graphite after high-temperature graphitization.
It has small graphite grains, low degree of graphitization and small crystal orientation.
It is better than natural graphite in terms of rate performance, cycle life, volume expansion and electrode rebound prevention.
The specific capacity and compaction density are also very close to natural graphite.
The gap is only 2% to 3%.
The advantages of graphite in the battery anode material:
1 - First, the graphite source is abundant.
2 - After being modified, the tap density is high.
3 - Electrochemical performance is stable.
4, the specific capacity can be compared with the theoretical capacity.
