Li- and Na-reduction products of meso-Co₃O₄form high-rate, stably cycling battery anode materials

Abstract

A meso-porous Co3O4has been found to retain its structure and cycle stably in a Li-ion or Na-ion battery.

Electrochemical characterization of Co3O4/MCNTs composite anode materials for sodium-ion batteries

“…Very recently, Wen and co-workers [29] have investigated bowl-like hollow Co 3 O 4 microspheres as anodes for Na-ion batteries but with unsatisfactory electrochemical properties. Optimizing the electrolyte is a good way to promote the stability of Co 3 O 4 /electrolyte interface with improved Na-ion storage behaviors [30][31][32]. In spite of these significant achievements, it is apparent that the electrochemical property of Co 3 O 4 in Na-ion batteries is still not as good as that in Li-ion batteries.…”

Mesoporous NiCo 2 O 4 nanosheets with enhance sodium ion storage properties

“…anode material for NIBs owing to its high theoretical capacity of 890 mA h g -1 [19,20]. However, because of toxic nature of cobalt and the volume change among the batteries charge and discharge, Co 3 O 4 has not been considered as an alternative anode material for large-scale manufacture [21].…”

Disodium dimolybdate: a potential high-performance anode material for rechargeable sodium ion battery applications

“…The main issues encountered with anode materials are (a) low capacity in case of insertion-type compounds, (b) large volume changes in case of both insertion as well as alloying reactions, (c) poor cycling performance of conversion-type materials, and (d) sodium plating at low voltages. In the literature, sodium storage in the conversion reaction-based systems involving binary [3][4][5] and ternary oxides [6] were explored as alternative to the insertion [7,8] and alloying [9,10] based compounds. We embarked on a comprehensive program on search for new anode materials in the ternary oxide regime containing sodium in the lattice via conversion reactions.…”
