锂电池主要材料

碳负极材料

实际用于锂离子电池的负极材料基本上都是碳素材料,如人工石墨、天然石墨、中间相碳微球、石油焦、碳纤维、热解树脂碳等。

锡基负极材料

锡基负极材料可分为锡的氧化物和锡基复合氧化物两种。氧化物是指各种价态金属锡的氧化物。没有商业化产品。

氮化物

没有商业化产品。

合金类

包括锡基合金、硅基合金、锗基合金、铝基合金、锑基合金、镁基合金和其它合金 ,也没有商业化产品。

纳米级

纳米碳管、纳米合金材料。

纳米氧化物

根据2009年锂电池新能源行业的市场发展最新动向,诸多公司已经开始使用纳米氧化钛和纳米氧化硅添加在以前传统的石墨,锡氧化物,纳米碳管里面,极大地提高锂电池的充放电量和充放电次数。

Main materials of lithium battery

Carbon anode materialThe actual negative electrode materials used in lithium-ion batteries are basically carbon materials, such as artificial graphite, natural graphite, mesophase carbon microspheres, petroleum coke, carbon fiber, pyrolysis resin carbon, etc.Tin-based anode materialTin-based anode materials can be divided into tin oxides and tin-based composite oxides. Oxides refer to oxides of metal tin in various valence states. There are no commercial products.nitrideThere are no commercial products.AlloysIncluding tin-based alloys, silicon-based alloys, germanium-based alloys, aluminum-based alloys, antimony-based alloys, magnesium-based alloys and other alloys, there are also no commercial products.nanoscaleCarbon nanotubes, nano-alloy materials.Nano oxideAccording to the latest market development trend of lithium battery new energy industry in 2009, many companies have begun to use nano-titanium oxide and nano-silicon oxide to add to the previous traditional graphite, tin oxide, and carbon nanotubes, which greatly improves the charging and discharging of lithium batteries. volume and charge and discharge times.
