Hard carbon
Hard carbon anode materials
JFE Chemical manufactures this hard carbon material (non-graphitizable carbon) from coal tar using original technology. As a product, it offers superior output and durability compared to graphite, as well as a level of performance suited to hybrid cars and electric vehicles.
Characteristics
-
Hard carbon, which is derived from coal tar pitch, has a high aromaticity, as well as a high true density, and high capacity, along with excellent output and durability. We have also developed small particle hard carbon(D50=3µm), featuring enhanced charge-discharge characteristics.
