▎ 摘  要

NOVELTY - Cathode activated material comprises graphite, which is obtained by Raman spectroscopy, where the ratio of the peak intensity ID1 at 1350 cm-1 and the peak strength IG1 at 1580-1 in the cathode activated material is in the range of 0.41-0.63. The Dv50 is 23.5-39.9 molar particle particles at the 1350 cm-1 peak strength ID2 and the 1580 cm-1 peak intensity IG2 in the ratio ID2/IG2 is 0.18-0.39. USE - The cathode activated material is useful in electrochemical device and electronic device (all claimed) e.g. lithium ion battery for driving portable electronic communication devices e.g. portable cameras, mobile phones and notebook computers. ADVANTAGE - The cathode activated material: controls the graphitization degree of particles with different grain diameters; and realizes the balance between the dynamic performance and the first efficiency of the electrochemical device. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electrochemical device, comprising the cathode activated material, and a conductive layer.
