NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY, NEGATIVE ELECTRODE, NEGATIVE ELECTRODE MATERIAL, AND PREPARATION OF SI-O-AL COMPOSITE
摘要：
An Si—O—Al composite comprising silicon, silicon oxide, and aluminum oxide exhibits a powder XRD spectrum in which the intensity of a signal of silicon at 28.3° is 1-9 times the intensity of a signal near 21°. A negative electrode material comprising the Si—O—Al composite is used to construct a non-aqueous electrolyte secondary battery which is improved in 1st cycle charge/discharge efficiency and cycle performance while maintaining the high battery capacity and low volume expansion upon charging of silicon oxide.
摘要（中）：

包含硅，氧化硅和氧化铝的Si-O-Al复合材料表现出粉末XRD光谱，其中28.3°的硅信号的强度是接近21°的信号强度的1-9倍。 使用包含Si-O-Al复合材料的负极材料来构造非水电解质二次电池，其在保持高电池容量和充电时的体积膨胀小的同时提高了第一循环充放电效率和循环性能 氧化物。
