ELECTROCHEMICAL PROPERTIES OF CATHODIC MATERIALS SYNTHESIZED BY LOW-TEMPERATURE TECHNIQUES

After having introduced the definition of 'low temperature techniques', the electrochemical properties of various cathodic materials (oxides) for secondary lithium batteries are reported. The influence of the way of synthesis upon their electrochemical behaviour is examined and illustrated through several examples. A presentation of electrochemical results discussed in relation with the specific chemical, physical and structural properties emphasizes the significant advances afforded by these techniques (sol-gel processes, precipitation, ion-exchange redox reactions, etc.) in obtaining new high-performance cathodic materials for secondary lithium batteries. The most interesting results are obtained for the vanadium and manganese systems.
