Li metal batteries pairing anode with high-nickel layer structured oxide cathode are a promising energy storage technology to achieve high density. To obtain long cycling life for batteries, the electrolyte plays pivotal role in stabilizing both and upon electrochemical cycling. Herein, we report carbonate that enables Li∥LiNi0.8Mn0.1Co0.1O2 pouch cell gravimetric density of 366 Wh/kg unprecedented stability 80% capacity retention after 335 cycles. The 19F quantitative nuclear magnetic...
Sodium-sulfur (Na-S) batteries have been commercialized for stationary energy storage systems because of their low-cost fabrication and long-cycling stability. However, the Na-S need to operate at high temperatures (> 300 o C) maintain molten state sodium anode sulfur cathode, which requires extra raises safety issues when solid electrolyte membrane fails. Therefore, low-temperature all-solid-state (such as 60 are highly desirable improved a lower operating temperature. To achieve...
All-solid-state sodium-sulfur (Na-S) batteries are promising for stationary energy storage devices because of their low operating temperatures (less than 100 °C), improved safety, and low-cost fabrication. Using Na alloy instead metal as an anode in Na-S can prevent dendrite growth improve interfacial stability between the solid electrolytes to achieve long-cycling stability. A high-sulfur content cathode possessing high sulfur utilization is also important enable energy-dense battery. In...
