Abstract
A simple and industrial scalable approach was developed to encapsulate metal oxide nanocrystals into porous carbon (PC) with a high distribution. With this method, the composite of PC-metal oxide were prepared in a large amount with a low cost; particularly they exhibit ultrahigh performances in lithium-ion battery applications. For example, the PC-CoOx and PC-FeOx show a high capacity around 1021 mA h g(-1) and 1200 mA h g(-1) at the current density of 100 mA g(-1) respectively, together with an excellent cycling ability (>400 cycles) and rate capacity even at the high current densities of 3 A g(-1) and 5 A g(-1).
