Abstract
|
:
|
We identified a group of NASICON open framework structured polyanion materials and examined the materials for rechargeable lithium battery application. We found that the open framework structure of these materials facilitated easy insertion/extraction of lithium into/from their structure. We synthesized the materials in lithium-rich [Li2M2(MoO4)3] and lithium-free [LixM2(MoO4)3] (M= Ni, Co) phases, for the first time, by means of a low temperature soft-combustion technique. The soft-combustion synthesis usually yields single-phase materials with high phase purity and is suitable for bulk preparation of battery grade electrode powders. The materials were characterized for structure, morphology and electrochemical lithium insertion/extraction kinetics and the results were presented and discussed in the light of XRD, SEM and electrochemical techniques in relation to the electrode-active character of the materials. All the materials were found to crystallize in a single phase structure with submicron sized particles. The electrode-active behavior of the new materials was examined in a twoelectrode configuration utilizing a Li+ non-aqueous environment. Both the systems were.
