Graphite is the primary anode material in electrical vehicle (EV) batteries. Typically, graphite is mined and concentrated to ~95% purity by companies such as Gratomic.

Graphite has attracted global interest due to its unique anisotropic properties, including excellent electrical and thermal ...

The battery materials startup raised significant Series D funding to expand its manufacturing capability. At the same time, ...

Lin said that Ascend Elements is able to take graphite that’s been contaminated during an initial shredding step back to 99.9% purity, exceeding EV industry requirements, while also retaining ...

Graphite is widely used as anode material in LIBs due to its stable electrochemical performance and high theoretical specific capacity (~372 mAh g−1) [v]. However, poor rates of fast-charging ...

At its core, silicon-carbon (Si/C) batteries remain lithium-ion cells. But what changes is the anode material. Instead of pure graphite, the anode is a composite of silicon and carbon.

Its graphite anode segment contributes a significant amount of global anode production.Imerys (EPA:NK) is a French multinational firm that provides mineral products, including synthetic graphite ...

Graphite can be found in nature as crystalline flakes or masses, which are mined and then processed to produce the small, spherical particles needed for anode manufacturing. Graphite is also ...

Current lithium-ion batteries (LIBs) use a graphite-based carbon (C) anode which has a limited Li storage capacity. Silicon (Si) and germanium (Ge) anodes exhibit significantly higher capacities ...

Once fabricated, the nanocomposite anodes would be used in batteries just like conventional graphite structures. That would allow battery manufacturers to adopt the new anode material without ...

Hierarchical porous silicon structures with extraordinary mechanical strength as high-performance lithium-ion battery anodes. Nature Communications, 2020; 11 (1) DOI: 10.1038/s41467-020-15217-9 ...

New research has identified a nanostructure that improves the anode in lithium-ion batteries. Instead of using graphite for the anode, the researchers turned to silicon: a material that stores ...
