如今,电动汽车爆发式增长,促进了动力电池产业的高速发展。截至目前,我国已成为世界上最大的锂资源消费国。然而,随着锂资源需求日益增加,需求量和储量之间的矛盾逐渐凸显,废旧动力电池若未得到妥善处理,势必带来资源浪费和环境污染。如何有效进行动力电池的梯次利用和锂资源回收,成为我国动力电池技术发展的重要课题之一。 Today, the explosive growth of electric vehicles, promote the rapid development of power battery industry. Up to now, China has become the largest consumer of lithium resources in the world. However, with the increasing demand for lithium resources, the contradiction between demand and reserves has gradually become apparent. If the old batteries are not handled properly, it is bound to bring about waste of resources and environmental pollution. How to effectively carry out the use of power battery and recycling of lithium resources has become one of the important topics for the development of power battery technology in China.
