L-Series

C-NERGY L-series - high-grade specialty graphite for lithium-ion batteries

The C-NERGY L-series graphites is a range of high purity, speciality, primary synthetic graphites designed and optimized for both positive and negative electrodes of lithium-ion batteries. These grades are characterised by their very high purity, electrical conductivity, reversible capacity, density, low spring back and very efficient electrolyte wettability. 
 
The comparative high degree of conductivity comes from their very high crystallinity. This allows manufacturers to achieve the same level of conductivity with a lower loading, enabling a higher degree of flexibility when it comes to anode design and cathode material mix. The structure also gives the battery a high charge acceptance and cycling stability, making it both easier to charge the battery itself and slower to decrease the charge loss with each consecutive recharge.
 
Due to its high electrode density and low spring back, the electrode will not rebound or expand when compressed. This allows manufacturers to design more compact batteries and optimise space. This compressibility enables improved mechanical stability, leading to improved battery safety and longevity.
 
The efficient wettability of C-NERGY L-series graphites makes them easily dispersible within the electrode slurry, resulting in improved battery performance because of efficient anode wetting by the electrode.
