    Great read!

    Love this quote ... regarding performance of test cells made from Ecograf's HF free recycled graphite:

    "As a result, the two-electrode graphite‖NMC532 provided remarkable cycling stability (Figure 5E) and capacity retention of 80% after about 1000 cycles (precisely, around 950 cycles; Figure 5F), confirming that the recycled graphite is a highly suitable active material for the assembly of new high-performance lithium-ion cells."smile.png
