近20年前，Li x C6/Li 1-x CoO2充电电池进入市场，不仅使蜂窝电话和笔记本电脑成为可能，而且推动了对高能量和高功率密度的充电和移动电源的需求不断增长。随着混合动力汽车的出现，这一需求将呈现爆炸式增长。LiCoO2正极的成功之处在于其高的Li+迁移率，相对于Li+/Li(∼4 V)的高电化学势。
The introduction of the Li x C 6 /Li 1– x CoO 2 rechargeable battery into the market place nearly 20 years ago not only enabled the cellular telephone and the laptop computer but also fueled an ever-increasing demand for rechargeable and mobile power sources with high energy and power density. This demand is poised to explode with the advent of the hybrid electric car. The success of the LiCoO 2 cathode resides in its high Li + mobility, its high electrochemical potential versus Li + /Li ( ∼ 4 V)
