Synthesis and electrochemical properties of composite cathode materials

Abstract

Original method for synthesis of LiFePO 4 /LiTi 2 (PO 4 ) 3 composite material is suggested. The method includes mechanical activation of a precursor in a high-pressure apparatus of the type of Bridgeman anvils. Electrodes prepared on the basis of this material have signifi cant advantages in discharge potential, capacity, and stability over the known foreign and domestic analogs.

Effect of mechanical activation on characteristics of electrodes based on fluorinated carbon nanotubes

“…We took for the experiment FMWCNT with 61% fl uorine content. The electrode fabrication process consists of several steps [10]. Fluorocarbon powder was mixed with a conducting additive on a ball mill in 85 : 10 ratio, and the resulting mixture was impregnated with a 5 wt % solution of SPE in dimethylacetamide.…”

Synthesis of Promising Cathode Material for Lithium Polymer Batteries

“…It has been shown previously that the mechanical activation of a precursor in a high-pressure apparatus of the Bridg man anvil type can be successfully used to synthesize h ighly dispersed cathode materials for lithiu m batteries [11][12][13]. Therefore, we studied the effect of mechanical activation on synthesis and electrochemical properties of lithium vanadium phosphate.…”
