Abstract

original image

A generic, facile, and rapid low-temperature, one-pot synthesis method is used to grow highly crystalline LiMn2O4 nanoparticles in situ within a homogeneously dispersed conductive percolation network of multi-walled carbon nanotubes (MWCNTs). The resulting LiMn2O4/MWCNT nanocomposite displays an unprecedented high rate capability (high power density) when used as cathode for lithium ion batteries.
