摘　　要：近年来,纳米碳材料在锂离子蓄电池电极材料中的应用受到广泛的重视,目前纳米碳材料主要有纳米碳纤维(Carbonnanofibers,CNFs)和纳米碳管(Carbonnanotubes,CNTs)两种,本文对这两种纳米碳材料作为锂离子蓄电池负极材料的研究进行了综述。纳米碳材料可以显著提高锂离子蓄电池的嵌锂容量,但存在首次充放电效率不高以及电位滞后的缺点。纳米碳材料作为锂离子蓄电池负极材料的掺杂体具有很高的实用价值,这是由于纳米碳管和纳米碳纤维具有高的比表面积、高的导电和导热性以及优良的机械性能。In recent years, carbon nano-materials are received much attention for the interest as electrode materials in lithium-ion batteries. Studies of carbon nano-materials including carbon nanofibers (CNFs) and carbon nanotubes (CNTs) in the areas of anode materials for lithium ion batteries were reviewed. Carbon nano-materials greatly increased the intercalation capacity, but has great irreversible loss and potential lag. As the adulterants, the practicable of carbon nano-materials is great, due to their high specific surface, very high electrical and thermal conductivity and excellent mechanical properties.
