Foreword

This Standard is drafted in accordance with the rules given in GB/T 1.1-2009. This Standard replaces GB/T 4369-2007 "Lithium". As compared with GB/T 4369-2007, the main changes of this Standard are as follows: - ADD product designation; - ADJUST the chemical composition of product; - MODIFY the appearance quality of product. This Standard was proposed by China Nonferrous Metals Industry Association. This Standard shall be under the jurisdiction of China National Technical Committee for Standardization of Nonferrous Metals (SAC/TC 243). Drafting organizations of this Standard. Fengxin Ganfeng Lithium Co., Ltd., China Energy Lithium Co., Ltd., Tianqi Lithium Co., Ltd., Lithium Branch of CNNC Jianzhong Nuclear Fuel Co., Ltd., Xinjiang Asia-Europe Rate Metals Co., Ltd.. Main drafters of this Standard. Xiong Xunman, Dai Xiaoyong, Li Qiang, Zhu Shigui, Chen Qiang, Jia Zhenyong, Ma Zhenqian, Jiang Hucheng, Zuo Yongjian, Zhang Jingdong, Wang Wenhong, Chen Yuedi. The previous releases of versions of the standard replaced by this Standard are. - GB/T 4369-1984; - GB/T 4370-1984; - GB/T 4369-2007. Lithium

1 Scope

China's national standard for lithium metal. It specifies the requirements, the test methods, the inspection rules and the packaging, marking, transport and storage. Lithium is the lightest metal and the most electropositive, which is the origin of both its value and its difficulty. Its value is the battery: the same properties give lithium cells an energy density nothing else approaches, and that has made the metal and its compounds strategically central. Its difficulty is handling - lithium reacts with water, with nitrogen at room temperature, and with the oxygen and moisture of ordinary air, so the metal is produced, stored and shipped under argon or under oil, and the packaging provisions in the standard are not routine. Metallic lithium as distinct from its compounds goes into primary batteries, into lithium metal anodes for the next generation of cells, and as an alloying addition to aluminium for aerospace.

This Standard specifies the requirements, test methods, inspection rules and marking, packaging, transportation and storage, quality certificate, and order form (contract) content of lithium. This Standard applies to the lithium metal prepared from anhydrous lithium chloride as raw material, by fused salt electrolysis, and refining; for use in chemical industry, nonferrous metal, medicine, synthetic rubber catalysis, smelting deoxidation, etc.
