廉价无烟煤变身平价电池材料

由 admin 于 星期二, 04/11/2017 - 22:51 发表

 

摘要（Teaser）: 

  近期，中国科学院物理研究所在钠离子电池碳基负极材料研究上取得了突破。科学家采用成本低廉的无烟煤作为前驱体，通过简单的粉碎和一步碳化得到了一种具有优异储钠性能的碳负极材料。与锂相比，钠储量丰富、分布广泛、成本低廉，并且与锂具有相似的理化性质，因而钠离子电池的研究再一次受到科研界和工业界的广泛关注。而与锂离子电池相比，钠离子电池的能量密度通常较低，虽不太适合应用在对能量密度有较高需求的便携式电子设备和电动汽车领域，但适合应用于对能量密度要求不太高、对成本敏感的低速电动车和通讯基站、家庭储能、电网储能等领域。高性能电极材料的开发对实现钠离子电池的商业化应用至关重要，特别是高性能、低成本的负极材料仍是制约钠离子电池实用化的瓶颈。
