DRIVE - Lithium-ion batteries

Graphene-silicon composite for high-capacity batteries.

Lithium-ion batteries are crucial for a future green energy society. An intensive research effort has led to many high-capacity solutions but these solutions lack low-cost industrial implementations. Our research has shown: 1) We have demonstrated a new method to grow 10-nanometer silicon nanoparticles on the graphene flakes. 2) Using this graphene-silicon composite in the anodes, we have demonstrated a 10% higher capacity over the best commercially available batteries.
