Owing to the lower cost and easy accessibility of potassium, potassium‐ion batteries are considered as potential substitutes for lithium‐ion batteries. A porous carbon monolith with ultrahigh pyridinic N content is successfully synthesized by Yu Chen, Chenglin Yan, and co‐workers in article 1702268, which exhibits excellent electrochemical performance, especially in terms of reversible capacity, for both K⁺ half‐cells and full‐cells.

碳单块：超高倍数吡啶N掺杂多孔碳单块，可为半电池和全电池应用提供高容量的K离子电池阳极（Adv。Mater.35 / 2017）

由于钾的成本较低且易于获取，因此钾离子电池被认为是锂离子电池的潜在替代品。Chen Yu，Yanchenglin及其合作者在文章1702268中成功合成了具有超高吡啶N含量的多孔碳整体材料，该材料对K ⁺半电池和全电池均表现出出色的电化学性能，特别是在可逆容量方面。细胞。
