dc.description.abstract目前商业化的锂离子电池普遍采用石墨类炭材料作为负极材料。石墨类碳负极具有价格低廉,来源广泛,导电性能好,比容量较高,相对嵌锂电位较低等优点,但在碳酸酯溶剂中,由于溶剂化锂离子很容易嵌入其特殊的层状结构,即与电解液相容性差,以及其较低的嵌锂电位,也导致在大电流充电条件下,易在材料表面形成锂枝晶,导致基于碳基负极材料的锂离子电池的快速充电性能差,影响了锂离子电池在快充电市场的大量应用。因此,对碳材料进行改性来提高其电化学性能,特别是大电流充电性能显得尤为重要。本论文针对碳负极材料高倍率充电性能差的缺点,研究了一种在较大充电电流条件下仍能提供高比能量型锂离子电池用多层复合结构负极材料及其制备方法,并...
dc.description.abstractLithium-ion batteries have taken a big market share in portable devices, and have rapidly become essential secondary batteries. Lithium-ion batteries are not only widely used in portable electronic devices such as cell phones and laptop computers, but also in power tools including hybrid electric vehicles (HEVs) and electric vehicles (EVs) in recent decades. Even in military, aerospace and satelli...
