Abstract

An optimized nanostructure design for high-power, high-energy lithium-ion batteries and supercapacitors is realized by fabricating a nanocomposite with highly dispersed nanoparticles of active materials in a nanoporous carbon matrix. A nano-LiFePO /nanoporous carbon matrix nanocomposite forms a bridge between a supercapacitor and a battery electrode and offers a reasonable compromise between rate and capacity.

摘要

通过在纳米多孔碳基体中制备具有高度分散的活性材料纳米颗粒的纳米复合材料,实现了用于高功率、高能量锂离子电池和超级电容器的优化纳米结构设计。一种纳米磷酸铁锂/纳米多孔碳基体纳米复合材料在超级电容器和电池电极之间架起了一座桥梁,并在速率和容量之间提供了合理的折衷。
