EN Lithium-ion batteries are not situable for electric vehicles with high millage, military power supplies and fixed power networks. Therefore, the Li-S batteries have been intensively investigated, due to the high capacity, low cost, widespread source, and nontoxicity. The development of Li-S batteries causes increasing need to find the methods for their recycling. Some of them are discussed in the paper. The recycling of Li-S cell relates to its anode, cathode, electrolyte, binder and separator. The Li-S battery should be fully charged before recycling. There are potential methods for recycling of lithium from anodes, especially by re-melting. It is also possible to recycle some materials from the cathodes, especially sulfur by re-melting and graphite by dry crushing, Eco-bat Technologies method or the method investigated by Xiang et al. There is no effective recycling methods for electrolytes, binders and separators. It is necessary to carry out further studies on them.
