LITHIUM TITANATE CELL WITH REDUCED GASSING |
摘要 |
A method of manufacturing a lithium cell is disclosed. The method can include providing a lithium cell having an operating voltage range, where the lithium cell includes a negative electrode, a positive electrode, and an electrolyte in contact with, and between, the negative electrode and the positive electrode. The negative electrode can include lithium titanate and the electrolyte can include an additive. The method can also include reducing the additive to form a coating on a surface of the negative electrode in contact with the electrolyte. The reducing step can include overcharging the lithium cell to a voltage greater than an upper limit of the operating voltage range and dropping a voltage of the negative electrode to 0.2-1V vs. lithium. |
