Abstract: An electrochemical cell that cycles lithium ions is provided. The electrochemical cell includes a positive electrode having a positive electroactive material selected from the group consisting of LiNixM2-xO2 (where M is selected from the group consisting of cobalt, manganese, aluminum, and combinations thereof and x≥0.8), and a negative electrode having a negative electroactive composite material including a carbonaceous material and silicon oxide (SiOx, 0.95≤x≤1.05). The positive electrode has a single-sided loading capacity at room temperature between about 4.5 mAh/cm2 and about 6.5 mAh/cm2. The negative electrode has a single-sided loading capacity at room temperature between about 4.5 mAh/cm2 and about 5.5 mAh/cm2.
