Aluminum-carbon anodes for Li-ion batteries show high capacity and stability

Researchers in S. Korea synthesized structurally regulated and hybridized aluminum-carbon (Al-C) nanoclusters as a stable, high-capacity anode material for Li-ion batteries. 

In a paper published in the RSC journal Chemical Communications, the team reported the Al-C hybrid nanoclustered anodes, tested in pouch-type half cells, exhibited a high reversible capacity of > 900 mAh g^-1 at an optimized current density of 6 A g^-1 for more than 100 cycles.

The Al-C nanoclusters are prepared from C₆₀ and Al precursors by thermal evaporation-combined plasma-enhanced chemical vapor deposition.

Cycling characteristics were tested at current densities of 6, 10, 15, and 20 A g^-1.
