Since 2000,Poizot et al began to use transition metal oxides as anode materials in lithium-ion batteries1,them have been paid continuously attention.These materials present a different reaction mechanism from intercalation materials like graphite and alloy materials like silicon.They are mostly through a converse reaction during charge-discharge process with a high theoretical capacities(～500-1000 mA h g-1) and safe voltage plateau (～0.5-1V vs.Li+/Li).

镁合金是目前可用的最轻的金属结构材料，其比强度和比刚度较高，弹性模量低，阻尼减震性能优越;同时具有良好的导热导电性、机加工性能及电磁屏蔽性能，近年来已成为世界最令人瞩目的绿色环保工程材料。近年来，镁及其合金在生物材料领域的潜在应用价值吸引了研究者的极大兴趣。但是，镁合金化学活泼性极高，易与空气中的氧气发生反应而生成疏松多孔、不致密的氧化膜，该氧化膜对金属基体起不到有效的保护作用.另外，当镁合金和大
