  • Anode active material including low-defect turbostratic carbon
    Patent number: 11929494
    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 (ID) at wave number between 1330 cm-1 and 1360 cm-1; a G band having a peak intensity (IG) at wave number between 1530 cm-1 and 1580 cm-1; and a 2D band having a peak intensity (I2D) at wave number between 2650 cm-1 and 2750 cm-1. In one embodiment, a ratio of ID/IG ranges from greater than zero to about 1.1, and a ratio of I2D/IG ranges from about 0.4 to about 2.
