Product Description

Artificial Graphite H9 for Power Lithium Battery


Category:

Artificial graphite

 

Advantages:

High energy density

Low expansion

Long circulation

2c quick charge

 

Application:

Artificial Graphite H9 is widely used to Power Lithium batteries. Power lithium battery has the advantages of high energy, high battery voltage, wide operating temperature range, long storage life and so on. It has been widely used in military and civil small electrical appliances, such as mobile phones, portable computers, cameras, cameras and so on, partly replacing the traditional battery.



Tips:

The gram capacity of material design is recommended to be 350-353mAh/g, and the average compaction density is recommended to be controlled at 1.60-1.65g/cc and below. This product is suitable for waterborne system.

 

Packaging requirements:

H9 artificial graphite needs to be put into a plastic bag with a size of 650mm×950mm, sealed, and then put into a carton with weight is 25+0.02kg/box, or packaged according to user requirements.

 

Transportation and storage:

a The product should be stored in a dry, ventilated place without other pollution sources (recommendation: temperature≤45℃, humidity≤85%);

b The stacking of products should be neat and tidy, and the production batch number, production date and other signs should be clearly identified;

c During transportation, it should be handled with care to avoid damage to the package; any products leaking out of the package should not be returned to the box.

d The shelf life is 2 years at room temperature.

 

Packaging and product identification:

The outer packaging of H9 products should be clearly marked, and the marking should include the following:

a) Product name:

b) Product batch number:

c) Product weight:

d) Date:

e) Company name:

 

Matters needing attention:

a) Ensure that the capacity of the negative electrode per unit area is greater than or equal to that of the positive electrode per unit area to avoid lithium evolution during charging.

b) Ensure that there is a good interface between the isolation film and the electrode.

c) The surface density and compaction density of the electrode will affect the performance of the rate capacity and performance.

d) This product is a single particle + secondary particle needle coke material, it is recommended that design compaction below 1.65g/cc is the best.
