Online PR News – 07-February-2011 – – Targray Technology International along with Vorbeck Materials Corp. has launched a new and disruptive graphene technology for manufacturers of Li-ion battery cells. The agreement names Targray as the exclusive global channel to market for the Vor-Charge Graphene Composite Anode Materials. Vor-Charge is based on a new technology that outperforms carbon nanotube and carbon black composites, and enables significantly increased cycle life and faster recharge rates.

The Vor-charge Graphene Composite Anode Material is a breakthrough material for the 21st century. Developed in collaboration with Princeton University and the Pacific Northwest National Laboratory (PNNL), Vor-Charge is a fully formulated anode composite with Li-ion storage material and graphene intimately mixed. This unique materials combination enables faster ion transport and electrical conduction, improving overall battery performance.

Targray’s Vor-Charge Graphene Composite Anode Material offers:
Improved cycle life – Issues associated with graphite particle fragmentation and loss of capacity due to large expansion and contraction are eliminated due to the mechanically flexible graphene sheets that buffer volume expansion Enhanced electron transport – The highly conductive graphene provides a robust network with strong electrical continuity

High efficiency – The high surface area of graphene coated with a thin layer of ion-storage material ensures even distribution and interconnection of the ion storage material and the conductive grapheme.
