Energy storage is critical for grid modernization and electrification of transportation infrastructure. Development of high-energy, low-cost battery technology with improved safety is a high priority. Among many options, two battery systems are identified to have the potential to reach an energy density higher than what is available in today’s Li-ion batteries: an Li metal anode coupled with high-Ni NMC, and an Li-S system. The materials and components need to be optimized to allow high-efficiency utilization of the active materials. Several common challenges will be addressed: (1) enabling high-efficiency utilization of Li metal, (2) increasing active materials loading and reducing parasite mass and inactive components, (3) improving packing density and ion transport, (4) increasing the stability window, and (5) reducing undesirable interfacial reactions and cross-contamination from the cathode to the anode. Under high-utilization conditions, the fundamental failure mechanisms may also differ from the experimental conditions widely studied in the literature.  Potential approaches to overcome the barriers for high materials utilization will be discussed
