Dual‐Ion Batteries: A Novel Aluminum–Graphite Dual‐Ion Battery (Adv. Energy Mater. 11/2016)

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.
