"adding atomic Fe changed the electronic structure of the carbon materials to promote more electrical conductivity... reduce the diffusion resistance of the Li+... synergistic effect of the atomic Fe and the formation of an Fe-N bond that exposed more active sties to which Li+ could adhere... anode delivered sustained electric power through 5000 cycles of high current density, providing both high energy and large power density. Its interlaced fiber structure conferred structural stability and improved conductivity"
