Higher purity graphite in battery anode materials offers several benefits for lithium-ion batteries. It allows for:

Enhanced electrical conductivity: This improves the battery’s ability to discharge and recharge efficiently1.

Higher energy density: Batteries can store more energy, which is crucial for applications like electric vehicles2.

Longer cycle life: Batteries can be charged and discharged more times before they start to degrade2.

Lower first cycle irreversible capacity loss: This means more of the battery’s initial charge capacity is retained after the first charge2.

Better safety performance: High purity graphite can help prevent issues like short-circuiting, which can lead to overheating or fires2.

Overall, the use of high-purity graphite contributes to the production of more reliable, efficient, and safe lithium-ion batteries.
