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 )-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 ) intercalation chemistry in graphite cathode and NH intercalation behavior in PTCDI (3,4,9,10-perylenetetracarboxylic diimide) anode. This new battery configuration successfully circumvented the reduction susceptibility of NH and the lack of mature NH -rich cathodes for NH ion batteries (AIBs). The customized organic NH electrolyte endows the graphite||PTCDI full battery with durable longevity (over 1000 cycles) and a high energy density (200 Wh kg ). We show that the development of AIBs should be high-voltage-oriented while circumventing low operation potential to avoid NH reduction.
由于对不可再生金属的严重依赖，流行的金属离子电池（MIB）存在环境和经济问题。在这里，我们提出了一种无金属的铵（NH ）基双离子电池，其工作电压达到了创纪录的 2.75V。这种可持续电池的工作机制涉及在石墨阴极中可逆的阴离子（PF ）嵌入化学和在 PTCDI（3,4,9,10-苝四羧酸二酰亚胺）阳极中 NH 嵌入行为。这种新的电池结构成功地避免了 NH 的还原敏感性和 NH 离子电池（AIB）缺乏成熟的富 NH 阴极。定制的有机 NH 电解质赋予石墨||PTCDI 全电池耐用的长寿命（超过 1000 个循环）和高能量密度（200 Wh·kg -1 ）。我们表明，AIB 的发展应该是高压导向的，同时避免低工作电位以避免 NH 的还原。
