Polydopamine-derived carbon (C-PDA) nanospheres embedded with zinc ferrite (ZnFe2O4) are synthesized by in situ polymerization of dopamine with zinc and iron species followed by carbonization. The composite nanospheres contain ZnFe2O4 nanoparticles ∼8 nm in size well dispersed in porous C-PDA. The unique structure and morphology endow the nanospheres with excellent rate capability and cycling stability for use as anodes in lithium-ion batteries.
通过多巴胺与锌和铁物种的原位聚合，随后进行碳化，合成了嵌入铁酸锌（ZnFe2O4）的聚多巴胺衍生碳（C-PDA）纳米球。复合纳米球包含尺寸约为8nm的ZnFe2O4纳米颗粒，其很好地分散在多孔C-PDA中。这种独特的结构和形态赋予了纳米球优异的倍率性能和循环稳定性，使其可用作锂离子电池的负极。
