Abstract

A negative electrode of a lithium ion electrochemical cell, the negative electrode including an active electrode material that includes a first component and a second component. The first component may include graphene, silicon, or a combination thereof. The second component may include silicon. The active electrode material may include particles in which the second component is encapsulated by the first component. The negative electrode may have an internal porosity of between 40 to 60 percent.
