“…The voltage trend is well indicative of typical characteristics of Co 3 O 4 electrode, that is, a long voltage plateau at about 1.08 V followed by a sloping curve down to the cut-off voltage of 0.01 V during the first discharge step. Similar results were obtained for cobalt oxides by research groups of Thackeray and coworkers [21,22]. Due to the Co 3 O 4 phase structure conversion from crystalline to amorphous state (see Fig.…”

“…The nature of the intermediate is thus rate/surface-dependent. This mechanism is consistent with the observations made by Thackeray et al [17] regarding the necessity of using fast chemical reduction instead of slow electrochemical reduction to be able to observe a LixCo 3 O 4 phase by X-ray.…”

Rechargeable lithium-ion batteries of today operate by an electrochemical process that involves intercalation reactions that warrants the use of electrode materials having very specific structures and properties. Further, they are limited to the insertion of one Li per 3D metal. One way to circumvent this intrinsic limitation and achieve higher capacities would be the use of electrode materials in which the metal-redox oxidation state could reversibly change by more than one unit. Through the discovery of conversion or displacement reactions, it is possible to reversibly change by more than one unit. Further, the need for materials with open structures or good electronic ionic conductivity is eliminated, thus leading to a new area in materials for lithium ion battery. In this paper, we present a review enlightens new reaction schemes and their potential impact on applications.

Cobalt ion-based coordination polymer nanowires were synthesized by using nitrilotriacetic acid (NA) as a chelating agent by a one-step hydrothermal approach. In the synthesis, cobalt ions were bonded with amino or carboxyl groups of NA to form one-dimension polymer nanowires, which can be confirmed by FTIR and TGA results. Our experimental results show that the morphologies of polymer nanowires greatly depend on the precursor salts, ratios between deionized water and isopropyl alcohol. The probable molecular formula and growth mechanism have been proposed. After heat treatment, the cobalt ion-based coordination polymer nanowires can be converted into porous Co(3)O(4) nanowires, which completely preserved the nanowire-like morphology. When used as anodes in lithium-ion batteries, the obtained porous Co(3)O(4) nanowires exhibited a high reversible capacity of 810 mA h g(-1) and stable cyclic retention at 30th cycle. The good electrochemical performance could be attributed to the porous nanostructure of Co(3)O(4), which provides pathways for easy accessibility of electrolytes and fast transportation of lithium ions.
