Graphite is the perfect material for the anode
It is coated onto a copper foil together with binder and usually also with conductive additives, forcing the lithium atoms to find a fixed place in the material’s lattice structure. This has the following advantages: higher cycle stability, better performance during rapid charging and higher quality consistency compared to other battery types (such as lead acid batteries).
The purer the graphite, the better this mechanism works. Synthetic graphite handles this task particularly well thanks to its optimized and customizable properties. SGL Carbon’s many years of experience in production ensure the consistent quality of the graphite.
Investment in graphite research
Graphite is indispensable as an anode material in the battery cell. However, due to the countless interactions, the material has different performance parameters and lifetimes in practice, depending on the type of battery. This makes it a enormous challenge for manufacturers of lithium-ion batteries.
It is precisely for this reason that SGL offers suitable services in the Battery Application Laboratory and relies on tailor-made battery graphite products that are developed for and with customers on the basis of its own manufacturing know-how.
As a development partner, technology expert and materials specialist, SGL Carbon also offers battery manufacturers the opportunity to test materials effectively, accurately and quickly in the Battery Application Laboratory.
