摘要: 随着锂离子电池行业的兴起,其负极材料也得到了蓬勃发展。我国在锂离子电池领域所占据的市场份额仅次于日韩,已有多家负极材料厂商处于世界先进水平。为了促进锂离子电池负极行业的健康发展,我国从2009年开始就陆续颁布了相关标准,涉及原料、产品和检测方法,提出了各项参数的具体指标,并给出了相应的检测方法,对负极材料的实际生产和应用起到了指导性作用。本文介绍了这些标准的主要内容和要点,包括晶体结构、粒度分布、密度、比表面积、pH值、水含量、主元素含量、杂质元素含量、首次放电比容量和首次充放电效率。此外,本文还对今后的标准制定工作提出了部分建议。

Abstract: With the rise of the lithium-ion batteries (LIBs) industry, its anode materials have also been booming. China's market share in the field of LIBs only lags behind Japan and South Korea, and many manufacturers of anode materials have reached the international advanced level. In order to promote the healthy development of anode material industry, China has promulgated relevant standards since 2009, including raw materials, products and detection methods. The specific technical indexes of physical and chemical properties are put forward, and the corresponding testing methods are given, which have played a guiding role in the actual production and application of anode materials. This paper introduces the main contents of these standards, including crystal structure, particle size, density, specific surface area, pH, moisture content, main element content, impurity element content, first discharging specific capacity and efficiency of anode materials. In addition, it also puts forward some suggestions for future setting work of standards.

Key words: lithium-ion batteries, anode materials, standards, technical indexes, testing methods
