Spherical graphite powder listed for secondary-battery anodes
Flake graphite spheroidized into high-FC powders (coated and uncoated ~18 µm grades) that the producer lists for secondary-battery anode use.
AI-assisted directory summary. Technical specifications, performance metrics, readiness and compliance labels are unverified unless individually supported and reviewed. Proposed partnership routes do not establish supplier consent, export eligibility, or willingness to sign an NDA. Confirm claims and test conditions with the linked sources and supplier before procurement or citation.
Problem solved
Anode makers need spherical natural-graphite powder with high packing density, low specific surface area and low oil absorption compared with flake, at a stated fixed-carbon level of 99.9% or higher.
Application contexts
- Secondary-battery anode material
- Resin and rubber conductive or thermal fillers
Technical principle
The producer states spherical graphite is made by mechanically spheroidizing flake graphite. Versus flake, it claims higher bulk density, lower specific surface area and lower oil absorption, plus directional conductivity and heat flow from the spherical shape. ASG-18 is uncoated (mean 17.5 µm); ACS-18 is coated (mean 18.0 µm).
Typical use cases
- Natural-graphite anode powder for lithium-ion cells
- Coated spherical graphite where a carbon coat is required
Partnership route
How global engineering teams typically engage this asset.
Helpful to include: target D50 and coating (ASG vs ACS) · required fixed carbon and impurity limits · electrochemical acceptance tests · annual tonnage and whether Koriyama or overseas conversion is acceptable
