Abstract:
The popular metal‐ion batteries (MIBs) suffer from environmental and economic issues because of their heavy dependency on nonrenewable metals. Here, we propose a metal‐free ammonium (NH 4 + )‐based dual‐ion battery with a record‐breaking operation voltage of 2.75 V. The working mechanism of this sustainable battery involves the reversible anion (PF 6 − ) intercalation chemistry in graphite cathode and NH 4 + intercalation behavior in PTCDI (3,4,9,10‐perylenetetracarboxylic diimide) anode. This new battery configuration successfully circumvented the reduction susceptibility of NH 4 + and the lack of mature NH 4 + ‐rich cathodes for NH 4 + ion batteries (AIBs). The customized organic NH 4 + electrolyte endows the graphite||PTCDI full battery with durable longevity (over 1000 cycles) and a high energy density (200 Wh kg −1 ). We show that the development of AIBs should be high‐voltage‐oriented while circumventing low operation potential to avoid NH 4 + reduction.
