The present disclosure provides an electrochemical cell that cycles lithium ions. The electrochemical cell includes a positive electrode and a negative electrode. The positive electrode includes a positive electroactive material and a lithiation additive blended with the positive electroactive material. The lithiation additive includes a lithium-containing material and one or more metals. The lithium-containing material is represented by LiX, where X is hydrogen (H), oxygen (O), nitrogen (N), fluorine (F), phosphorous (P), or sulfur (S). The one or more metals are selected from the group consisting of: iron (Fe), copper (Cu), cobalt (Co), manganese (Mn), and combinations thereof. The negative electrode may include a volume-expanding negative electroactive material.
