what is graphite electrode bulk density graphite

LIB Anode, Graphite

However, since most natural graphite has a flaky structure and low bulk density, the low electrode density characteristic makes it difficult to actually increase the battery capacity. Additionally, natural graphite has a tendency to become a planar structure on the electrical current collector, making it have low wettability characteristics.

Graphite Electrode – Loyal Road Inc.

Graphite has high thermal conductivity and is very resistant to heat and impact. It also has low electrical resistance, which means it can conduct the large electrical currents needed to melt iron. In recent years, graphite electrodes have been made even more efficient: they can now conduct even higher currents and more power.

Graphite

Therefore graphite cannot be directly applied to a anode electrode material of an NIB. In order to achieve Na + storage of graphite, the effective method is to increase the graphite layer spacing. Carbon has a "card house" structure containing graphite-like crystallites and amorphous regions [42] .
