In this paper we report the study of a high capacity Sn-C nanostructured anode and of a high rate, high voltage Li[Ni(0.45)Co(0.1)Mn(1.45)]O(4) spinel cathode. We have combined these anode and cathode materials in an advanced lithium ion battery that, by exploiting this new chemistry, offers excellent performances in terms of cycling life, i.e., ca. 100 high rate cycles, of rate capability, operating at 5C and still keeping more than 85% of the initial capacity, and of energy density, expected to be of the order of 170 Wh kg(-1). These unique features make the battery a very promising energy storage for powering low or zero emission HEV or EV vehicles.
本文研究了一种高容量的 Sn-C 纳米结构阳极和一种高倍率、高压 Li[Ni(0.45)Co(0.1)Mn(1.45)]O(4)尖晶石阴极。我们将这种阳极和阴极材料组合在一种先进的锂离子电池中,通过利用这种新的化学物质,在循环寿命方面表现出优异的性能,即大约 100 次高倍率循环,高倍率性能,在 5C 下运行时仍保持初始容量的 85%以上,以及能量密度,预计约为 170 Wh kg(-1)。这些独特的特性使得该电池成为一种非常有前途的储能设备,可用于为低排放或零排放的混合动力电动汽车或电动汽车提供动力。
