以热塑性酚醛树脂（PF）为碳源，硝酸铜（CN）为模板剂，采用油包醇乳液法制备了具有大量微孔和中孔的多级多孔碳微球（HPCM）。研究了CN负载量对HPCM形貌和结构的影响。结果表明，当PF与CN的质量比为1：4时，HPCM不仅能保持多级多孔微球结构，而且具有较高的电化学性能，在50 mA g − 1电流密度下的可逆容量为585 mA h g− 1，用作锂离子电池负极材料时具有良好的高倍率性能。
Novel hierarchical porous carbon microspheres (HPCM) with quantities of micropores and mesopores have been prepared by an alcohol-in-oil emulsion technique using thermoplastic phenolic formaldehyde resin (PF) as the carbon source and copper nitrate (CN) as the template precursor. The effects of CN loading content on the morphology and structure of HPCM were investigated. The results showed that, when the mass ratio of PF and CN is 1:4, the HPCM not only can maintain hierarchical porous microsphere structure, but also display high electrochemical performance with a reversible capacity of 585 mA h g−1at a current density of 50 mA g−1and favorable high-rate performance when used as the anode materials for lithium-ion batteries.
