New NASICON type oxyanion high capacity anode, Li2Co 2(MoO4)3, for lithium-ion batteries: Preliminary studies

We describe in this paper the lithium insertion/extraction behavior of a new NASICON type Li2Co2(MoO4)3 at a low potential and explored the possibility of considering this new oxyanion material as anode for lithium-ion batteries for the first time. Li 2Co2(MoO4)3 was synthesized by a soft-combustion...
