Modifications of synthetic graphite for secondary lithium-ion battery applications

Experimentally, three types of synthetic graphite from TimRex (SFG44, SFG15 and KS6) were plated with copper electrolessly. The specific capacities of untreated TimRex samples are typically in the range of 140-280 mA h/g, wit h low coulombic efficiencies in the first few cycles of charge and discharg e. Electroless copper plating on these graphites could substantially improv e the material performance in discharge capacity and coulombic efficiency. Some improvement in high rate dischargeability was also observed. (C) 1999 Elsevier Science S.A. All rights reserved.
