In article number 1502588, Yongbing Tang, Chun-Sing Lee, and co-workers report a novel aluminum-graphite dual-ion battery (AGDIB) mainly composed of only environmentally friendly low-cost materials (i.e., aluminum as counter electrode, graphite as positive electrode), and a specially designed carbonate electrolyte. A packaged AGDIB is estimated to deliver an energy density of ≈150 Wh kg−1 at a power density of ≈1200 W kg−1, which is ≈50% higher than most commercial lithium ion batteries.
Organic Solar Cells
On-fabrication solid-state N-doping of graphene using a fluorosurfactant (Zonyl)-added ZnO layer on a graphene surface is developed by Tae-Woo Lee and co-workers, in article number 1600172. The N-doping facilitates efficient electron transfer from the ZnO layer to the graphene cathode. Based on this, inverted organic solar cells with a power conversion efficiency of 7.5% are fabricated, which is 100% power conversion efficiency with respect to the ITO cathode.
