Method of Synthesis of Electrode Materials with Controlled Particle Size for Lithium Batteries

Abstract

The particle size of the active cathode materials for lithium ion batteries plays an important role for the electrochemical behaviour of the cell [1-5]. Two main technological principles are in the basis of proposed method of synthesis of active electrode materials with controlled particle size: a convective drying in liquid agent followed by firing in gas media. Varying the parameters responsible for the obtained particles size, as volume of drops and concentration of starting solution, it can be synthesised homogeneous electrode materials with controlled grain size ranged form 1.5 μm to 50 nm.
