摘 要

随着便携电子设备、混合电动汽车和电动汽车等领域的研究发展, 体积小、能量密度大的铿离子电池具有良好的发展前景，但是锂金属的化学特性非常活泼，使得锂金属的加工、保存、使用，对环境要求非常高，因此，锂电池长期没有得到应用，其发展也被极大地被限制住了。但是，随着现代科学技术的飞速发展，锂电池已经成为了人类日常的生产生活中的主流要素。锂离子电池技术在当今这个时代非常的重要，因为这种电池为交通工具的电动化的发展提供了巨大的动力与希望，可以说，锂离子电池新材料的开发是全球材料科学领域最重要的研究领域之一，也是在过去的二十年间现代电化学领域发展最为迅速的一个课题之一。同时，在锂离子电池迅猛发展的那段时光中，其被认为是现代电化学中最令人印象深刻的成功事例之一。在我们的实验中，我们选择了三种不同的氧氛围来做实验比较：（1）空气；（2）纯氧；（3）臭氧。在这三种不同的氧氛围下，我们得到了不同的形态的电极结构。通过扫描电镜和X射线衍射仪可以比较这三种氧氛围条件下制得电极的微观形态及离子混排纯度。通过对比，我们得出结论：这三种氧气氛中，比较适宜的LiNi_0.8Co_0.1Mn_0.1O₂材料制备的氧气氛是纯氧。

Fabrication of an anode material (LiNi_0.8Co_0.1Mn_0.1) of Li ion battery under different oxidizing atmosphere

Abstract

With the development of portable electronic equipment, hybrid electric vehicles and electric vehicles and other fields, small size, energy density of Keng ion battery has a good development prospects, but the chemical properties of lithium metal is very lively, making lithium metal processing, preservation , The use of the environment is very high, therefore, lithium batteries have not been applied for a long time, its development has also been greatly limited. However, with the rapid development of modern science and technology, lithium battery has become a daily human production and living in the mainstream elements. Lithium-ion battery technology in today's era is very important, because this battery for the development of the motorization of the vehicle provides a great impetus and hope that it can be said that the development of lithium-ion battery materials is the world's most important material science One of the areas of research is one of the most rapidly developing topics in the field of modern electrochemistry over the past two decades. At the same time, in the period of rapid development of lithium-ion batteries, it is considered one of the most impressive examples of modern electrochemistry. In our experiments, we chose three different oxygen atmospheres for experimental comparisons: (1) air; (2) pure oxygen; (3) ozone. In these three different oxygen atmospheres, we get different forms of electrode structures. The microstructures and ionization purity of the electrodes were compared by scanning electron microscopy and X - ray diffractometer. By comparison, we conclude that the oxygen atmosphere prepared by the more suitable LiNi0.8Co0.1Mn0.1O2 material in these three oxygen atmospheres is pure oxygen.
