LITHIUM SECONDARY BATTERY AND ELECTRODES FOR USE THEREIN

摘要

The present invention relates to a positive electrode for a rechargeable lithium ion battery comprised of single particles containing a compound of the formula LiMPO 4 , whereby M is a metal selected from the group consisting of Co, Ni, Mn, Fe, Ti or combinations thereof, and whereby in a X-Ray diffraction chart of the electrode the ratio of the intensity I 1 : I 2 of two selected peaks 1 and 2 is larger than 9:1 and wherein I 1 represents essentially the intensity of peak 1 assigned to the (020) plane and I 2 represents the intensity of peak 2 assigned to the (301) plane. The invention relates further to a process for the manufacture of such a positive electrode and to a battery comprising such an electrode.
