ABSTRACTTin(Sn) and its alloys have been attracting attentions as a negative electrode material for sodium-ion secondary batteries with high theoretical capacity (Na15Sn4, ca. 847 mAh/g) and high electromotiveforce. There still remains the issue as regards the discharge capacity decrease with increasing the number of cycles. In order to improve cycle performance, there are many studies such as using Sn-Ni alloy, however, using Sn based alloy as negative electrode materials and it suffer from the disadvantage of lowering of discharge capacity. In this study, a deposition process for making Sn film which consists of amorphous structure for negative electrode of sodium ion secondary batteries utilizing electordeposition from aqueous bath was developed. The effect of additives on the surface morphology and microstructure of Sn film was investigated. Furthermore, we evaluated the effect of amorphous structure in the Sn film on cycle performance of the Sn negative electrode. Sn film has a good cycle characteristic (>50 cycles) and discharge capacity (> 400 mAh/g). Amorphous structure in the Sn film showed a microscopic effect on the volume change by sodiation and desodiation.

Negative Electrode Materials

In order to enhance the electrochemical properties of Co-B alloys used as negative electrode materials of alkaline rechargeable batteries, Co-B alloy was successfully prepared by a chemical reduction method with the assistance of the sonication. The phase structure and the surface morphology of the as-prepared Co-B alloys were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and nitrogen physisorption. Moreover, the electrochemical performance was characterized by galvonostatic charge-discharge tests, electrochemical impedance spectroscopy (EIS) and anodic polarization (AP). Co-B alloy prepared with the assistance of the sonication consists of small particles with a uniform distribution. The electrochemical measurements showed that at a discharge current density of 100 mA/g, the initial discharge capacity was 858.1 mAh/g and the discharge capacity was 322.6 mA/g even at the 100th cycle with the capacity retention of 37.6%.

Intercalation Reaction

A hindrance to the practical use of sodium-ion batteries is the lack of adequate anode materials. By utilizing the co-intercalation reaction, graphite, which is the most common anode material of lithium-ion batteries, was used for storing sodium ion. However, its performance, such as reversible capacity and coulombic efficiency, remains unsatisfactory for practical needs. Therefore, to overcome these drawbacks, a new carbon material was synthesized so that co-intercalation could occur efficiently. This carbon material has the same morphology as carbon black; that is, it has a wide pathway due to a turbostratic structure, and a short pathway due to small primary particles that allows the co-intercalation reaction to occur efficiently. Additionally, due to the numerous voids present in the inner amorphous structure, the sodium storage capacity was greatly increased. Furthermore, owing to the coarse co-intercalation reaction due to the surface pore structure, the formation of solid-electrolyte interphase was greatly suppressed and the first cycle coulombic efficiency reached 80%. This study shows that the carbon material alone can be used to design good electrode materials for sodium-ion batteries without the use of next-generation materials.
