  • Patent number: 10424814
    Abstract: Electrolytes, anodes, lithium ion cells and methods are provided for preventing lithium metallization in lithium ion batteries to enhance their safety. Electrolytes comprise up to 20% ionic liquid additives which form a mobile solid electrolyte interface during charging of the cell and prevent lithium metallization and electrolyte decomposition on the anode while maintaining the lithium ion mobility at a level which enables fast charging of the batteries. Anodes are typically metalloid-based, for example include silicon, germanium, tin and/or aluminum. A surface layer on the anode bonds, at least some of the ionic liquid additive to form an immobilized layer that provides further protection at the interface between the anode and the electrolyte, prevents metallization of lithium on the former and decomposition of the latter.

  • Patent number: 10381681
    Abstract: The present application relates to the technical field of lithium-ion batteries and, specifically, relates to an electrolyte and a lithium-ion battery containing the electrolyte. The electrolyte of the present application comprises an organic solvent, a lithium salt and an additive, wherein the additive contains a cyanosulfone compound and a lithium fluorophosphate compound. When the electrolyte contains both the cyanosulfone compound and the lithium fluorophosphate at the same time, the cyanosulfone compound will form a passive film on the surface of the electrode of a high-voltage battery, so as to effectively suppress reaction between the electrolyte and the electrode, further, the lithium fluorophosphate can effectively suppress the decomposition of the lithium salt and improve the film resistance of the electrode. Under the synergistic effect of the two, the cycle performance of the lithium-ion battery is greatly improved, and the storage performance of the electrolyte is also significantly improved.
