Aluminum-carbon anodes for Li-ion batteries show high capacity and stability
2 December 2013
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. (Earlier post.)
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.
