Lithium-ion batteries (LiB)
ENERGY STORAGE TECHNOLOGY IS GROWING USING GRAPHITE POWDERS
A battery needs to be able to store a maximum amount of potential energy transformable into electricity. The lithium-ion battery is one of the most widespread energy storage methods in the world. We find lithium batteries in electric vehicles but also in renewable energy storage and in most domestic electrical appliances.
SUPPLY OF ANODE MATERIALS FOR LIB BATTERIES
anGlobal demand for batteries is growing rapidly. A major component of lithium-Ion batteries (LiB) is synthetic graphite used as anode. Demand for these never ceases to grow.
Synthetic graphite , also named artificial graphite in opposition to natural graphite, is obtained by the graphitisation of a mix of pre-baked petroleum coke and and coal-tar pitch. During a high-temperature (between 2,600° and 3,000°C) process, the carbon atoms rearrange themselves into hexagonal, crystalline structures, thus creating synthetic graphite. The synthetic graphite is a stable crystalline form of the carbon presenting a pile of layers of graphene in various forms.
The synthetic graphite in the lithium-ion batteries application presents the advantage to allow the insertion of the atoms of Lithium between its layers of graphene to form an intercalary compound (ex LiC6). This allows to resist to the exfoliation phenomenon and to obtain a low irreversibility during the first load/discharge cycle.
Carbone Savoie aims to become a major supplier for anode materials for different applications and therefore various electrolytic systems of lithium-Ion batteries.
Thanks to a knowledge of the worldwilde coke market, a rigorous selection of primary materials and an expertise in the process, Carbone Savoie can adjust its synthectic graphite properties.
