In this paper, by using the superabsorbent polymers (SAPs) from baby diaper, the 3D porous composites decorated with NiO and Ni nanoparticles (NNSCs) have been prepared via a facile dissolving‐freeze drying and subsequent annealing reactions. The porous carbon matrix (PCM) derived from the SAPs also provides a continuous highly conductive network to facilitate the fast charge transfer and form a stable solid electrolyte interface film. Furthermore, NNSC can exhibit the high specific capacity and excellent cycle performance as anode materials for lithium‐ion batteries. And more importantly, employing the PCM derived from baby diaper offers a green approach for other energy storage materials.

婴儿尿布启发的用于长期锂离子电池的3D多孔复合材料的构造

在本文中，通过使用婴儿尿布中的超吸收性聚合物（SAP），通过方便的溶解-冷冻干燥和随后的退火反应，制备了装饰有NiO和Ni纳米粒子（NNSC）的3D多孔复合材料。衍生自SAP的多孔碳基质（PCM）还提供了连续的高导电网络，以促进快速电荷转移并形成稳定的固体电解质界面膜。此外，NNSC可以作为锂离子电池的负极材料展现出高比容量和出色的循环性能。更重要的是，采用源自婴儿尿布的PCM为其他储能材料提供了绿色的方法。
