Facile synthesis of spongy NiCo(2)O(4) powders for lithium-ion storage

Spongy NiCo(2)O(4) powders were prepared by solution combustion synthesis (SCS) method for lithium ions storage. The effects of combustion parameters including fuel type (l-lysine, glycine, and urea) and fuel amount on the lithium storage performance of NiCo(2)O(4) powders were analyzed by various c...

Sumario:Spongy NiCo(2)O(4) powders were prepared by solution combustion synthesis (SCS) method for lithium ions storage. The effects of combustion parameters including fuel type (l-lysine, glycine, and urea) and fuel amount on the lithium storage performance of NiCo(2)O(4) powders were analyzed by various characterization techniques. Single-phase NiCo(2)O(4) powders with extremely porous microstructure showed a strong drop of initial specific capacity up to 350 mAhg(−1) which was recovered up to 666 mAhg(−1) following 100 charge/discharge cycles. However, the NiCo(2)O(4) powders prepared by the urea and l-lysine fuels with the compacted microstructure showed the capacity loss without any recovery. The spongy NiCo(2)O(4) powders showed an acceptable capability rate performance (404 mAhg(−1) @ 400 mAg(−1)).
