AVIC BIAM successfully applied graphene materials into Lithium-ion battery

2015-06-26

By taking full advantages of graphene nanosheets (GNS), carbon nanotubes and conductive carbon black, the Research Center of Graphene Applications, AVIC Beijing Institute of Aeronautical Materials (AVIC BIAM) made a breakthrough in the design and preparation technology of conductive graphene-based composites. The center successfully developed conductive slurry with graphene-based composite, featuring ultra-high specific surface area, ultra-strong conductivity, ultra-large quantity of active sites, as well as controllable conductivity and stable performance. This slurry has been successfully employed already as the anode material for realizing Li-ion battery with high energy density and high power density, which has passed material evaluation and verification.

BIAM has achieved batch production of low-cost and high-quality GNS with this proprietary technology. Through adopting a special technology of GNS surface modification and activation, the corrugated and porous structure of graphene can be controlled by BIAM, which plays an important role in the development of graphene-based composite applied in the Li-ion battery.

These kinds of new graphene-based materials in the Li-ion battery would enhance the conductivity of the anode, improve the intercalation/deintercalation properties of Li+ ion and reduce the performance-loss at low temperature, as well as upgrade Li-ion battery industry and clean energy battery industry.
