Lithium-ion batteries (LIBs) have become advanced energy storage technologies; however, specific capacity remains limited by the active materials in cathodes. Here, we report Li-LiNO batteries (LNBs) where LiNO in electrolyte serves as both active materials and ion conductor at room temperature. LNBs operate on a highly reversible redox between NO and NO, which results in an impressive areal capacity of 19 mAh cm at a plateau voltage of 1.75 V. Furthermore, the pouch cell exhibits stable cycling at a capacity of 100 mAh. This research underscores the potential of LNBs for high-capacity energy storage.
锂离子电池（LIBs）已成为先进的储能技术；然而，其比容量仍然受到阴极活性材料的限制。在此，我们报道了锂-硝酸锂电池（LNBs），其中电解质中的LiNO在室温下既作为活性材料又作为离子导体。LNBs在NO和NO之间进行高度可逆的氧化还原反应，在1.75 V的平台电压下实现了令人印象深刻的19 mAh cm的面积容量。此外，软包电池在100 mAh的容量下表现出稳定的循环性能。这项研究突出了LNBs在高容量储能方面的潜力。
