Starch is a modern and prospective biodegradable material, which could improve lithium-ion batteries by making them safer and thus increasing the energy density and capacity of the cells. The main aim of this study was to research the influence of the physical and chemical properties of different botanical origin starches on their electrochemical properties. The investigation was carried out by examining the colloid stability of starches in water solution at room temperature, and the size of particles, which gave really good stability results. Moreover, the vibrations and the functional groups structure were described by Fourier Transform Infrared Spectroscopy (FTIR). The surface properties were characterized by determining the specific surface area, pore diameter and volume diameter. The structures of the granules were determined by scanning electron microscope (SEM) measurement. The results of the electrochemical investigations showed good cyclic reversibility and stability.

The research was aimed at improving and modifying current lithium-ion cells using biodegradable material as an active anode material, which is connected with the currently well-known “Green Chemistry”.

生淀粉的理化性质及其对电化学活性的影响-基于生物分子的负极材料。

淀粉是一种现代且有希望的生物可降解材料,它可以通过使锂离子电池更安全并因此提高其能量密度和容量来改善锂离子电池。这项研究的主要目的是研究不同植物来源淀粉的物理和化学性质对其电化学性质的影响。通过在室温下检查淀粉在水溶液中的胶体稳定性和颗粒尺寸来进行研究,从而给出了非常好的稳定性结果。此外,通过傅立叶变换红外光谱法(FTIR)描述了振动和官能团的结构。通过确定比表面积,孔径和体积直径来表征表面性质。通过扫描电子显微镜(SEM)测量来确定颗粒的结构。电化学研究的结果显示出良好的循环可逆性和稳定性。

这项研究旨在使用可生物降解的材料作为活性阳极材料来改进和修饰当前的锂离子电池,该材料与目前众所周知的“绿色化学”相关。
