制造低维氧化物和碳的复合材料是实现更好的储能材料的最有效策略之一。在各种碳中，生物质衍生碳具有许多显著的特点，显示出很大的优势。我们在此报道了一种用于高性能复合电极材料的高度有序的软体动物-贝壳衍生的3D碳网络（MSDCN）。当选择Ni(OH)2作为连接组分时，得到的Ni(OH)2/MSDCN复合材料在30 a g−1的高电流密度下具有81 mAh g−1的高比容量，并且在6 a g−1的长寿命循环中没有明显的容量衰减。基于Ni(OH)2/MSDCN的对称固态储能器件在0.51 KW kg−1的功率密度下具有10.7 W h kg−1的高能量密度，且具有良好的10000次循环稳定性。红色发光二极管（LED, 2 V）可以很容易地被制备的固态器件点亮。同时，co3o4纳米立方/MSDCN和mno2纳米线/MSDCN复合材料的成功合成进一步揭示了MSDCN在高性能储能器件方面的巨大应用潜力。
Making composites of low-dimension oxides and carbons is one of the most effective strategies towards better energy storage materials. Among various carbons, biomass derived carbons with many distinguishing features show great advantages. We report herein a highly ordered mollusc-shell derived 3D carbon networks (MSDCN) for high-performance composite electrode materials. When Ni(OH)2is chosen as a conjoined component, the obtained Ni(OH)2/MSDCN composite exhibits a high specific capacity of 81 mAh g−1at a high current density of 30 A g−1, and shows no obvious capacity fading during long life cycling at 6 A g−1. Symmetric solid-state energy storage devices based on Ni(OH)2/MSDCN are also assembled, which demonstrates a high energy density of 10.7 W h kg−1at a power density of 0.51 KW kg−1with good cycling stability over 10000 cycles. Red light-emitting diode (LED, 2 V) can be easily lightened by the prepared solid-state devices. Meanwhile, the successful synthesis of Co3O4nanocube/MSDCN and MnO2nanowire/MSDCN composites further reveal the high application potential of the MSDCN for high performance energy storage devices.
