Abstract
An electrode material for a lithium ion secondary battery and method of forming the same, the electrode material including composite particles, each composite particle including: a primary particle including an electrochemically active material; and an envelope disposed on the surface of the primary particle. The envelope includes turbostratic carbon having a Raman spectrum having: a D band having a peak intensity (I) at wave number between 1330 cmand 1360 cm; a G band having a peak intensity (I) at wave number between 1530 cmand 1580 cm; and a 2D band having a peak intensity (I) at wave number between 2650 cmand 2750 cm. In one embodiment, a ratio of I/Iranges from greater than zero to about 1.1, and a ratio of I/Iranges from about 0.4 to about 2.
