Abstract
In an example of a method for improving a life cycle of a battery containing a lithium-silicon negative electrode, the battery is provided. The battery includes a positive electrode; the lithium-silicon negative electrode, which has at least 10% of its capacity attributed to a silicon-based active material; a separator positioned between the positive and negative electrodes; and an electrolyte. The battery is operated within a voltage potential window ranging from about 0.7 V and about 0.07 V versus a lithium reference electrode.
