本发明提供一种负极材料硅基材料/聚苯胺/石墨烯复合材料的制备方法及其产品和应用，通过给硅基材料包覆导电高分子聚苯胺来实现有机与无机的复合，外表面通过聚电解质修饰包覆氧化石墨烯，随后通过水合肼对氧化石墨烯还原得到硅基材料/聚苯胺/石墨烯复合材料。中间层导电聚合物聚苯胺在机械韧性方面远优于碳材料，能更好的缓冲硅在充放电过程中产生的巨大体积变化。外层石墨烯极大地提高体系的导电性。该材料综合了硅的高比容量、聚苯胺的高韧性和石墨烯的良好导电性等优点，具有优异的循环和倍率性能，在500 mA g‑1的电流密度下，经过200次循环比容量保持在710 mAh g‑1，可广泛应用在车用动力锂电池负极材料领域。
