锂作为一种能源金属，在许多工业领域的广泛应用中具有重要意义，沿着其在新兴电动汽车中的关键作用。中国是锂及相关产品的主要使用国和生产国。为了描绘锂循环的全貌，本研究试图量化2007年至2014年中国人为循环中锂的流量、库存和损失。本文采用物质流分析方法进行数据挖掘和汇编。结果表明，由于锂离子电池的快速增长，2007 - 2014年生产和使用量大幅增加。中国的锂产业仍然严重依赖天然锂矿的进口，锂出口主要是以锂离子电池为动力的产品，包括笔记本电脑、移动的手机和电动自行车。从2007年到2014年，锂的库存逐渐增加，但直接使用的锂损失也在增加，而且速度更快。因此，社会上的锂库存不能提供有意义的数量作为锂生产的第二来源。建议对电池中的锂进行回收，因为大部分锂投入都分散回了环境中，而中国的锂产业仍然依赖进口锂资源。(C)2016爱思唯尔B.

Lithium as an energy metal has gained significance in a wide range of application that spread across many industry sectors, along with its key role in emerging electric vehicles. China is a key use and producer of lithium and related products. In order to draw an entire picture of the lithium cycle, this study attempts to quantify the flows, stocks, and loss of lithium in the anthropogenic cycle in China, from 2007 to 2014. Substance Flow Analysis is employed in this paper for data mining and compilation. The results illustrate that production and use increased greatly from 2007 to 2014, due to the fast increase of the lithium ion battery. China's lithium industry still heavily relied on the import of natural lithium ores, where lithium exports were mainly in the form of lithium ion battery-powered products, including laptop computers, mobile phones and electric bicycles. The stocks of lithium increased gradually from 2007 to 2014, but the loss of lithium from direct use also increased and more quickly. Therefore, the lithium stock in society cannot provide meaningful quantities as the second source for lithium production. It is suggested that the lithium in batteries should be recovered, as most lithium inputs are dispersed back into the environment, while the lithium industry still relies on imported lithium resources in China.
