一种锂电池电极生产用的石墨包覆碳化设备 技术领域
本发明涉及一种电极生产设备，具体是一种锂电池电极生产用的石墨包覆碳化设备。
背景技术
石墨粉和石墨膜等石墨材料由于其独特的电学和热学性能，应用越来越广泛。石墨用在锂离子电池中具有工作电压高、比能量大、重量轻、体积小、循环寿命长、可快速充放电和无环境污染等优点，但是石墨与电解液的相容性较差，限制了纯石墨在锂离子电池中的应用。因此必须对石墨材料进行改性，在石墨表面包覆一层无定形碳材料，提高了振实密度，使电池充放电容量增大。包覆石墨反应过程一般是先将石墨分散于液体包覆材料或熔化的包覆材料中，然后将溶剂或包覆材料蒸发使无定形炭前驱体包覆在石墨材料表面，然后进行碳化。在加工的过程中由于碳化炉的设备构造，存在搅拌不均匀及碳化效果差等缺点，造成能量的巨大损失，生产成本高。
