Superior electrochemical properties of LiMn2O4 yolk-shell powders prepared by a simple spray pyrolysis process
LiMn2O4 yolk-shell powders with a distinctive filled-core@void@shell configuration are prepared by a spray pyrolysis process. The yolk-shell powders have discharge capacities of 127, 120, and 115 mA h g(-1) after 200 cycles, even at high current densities of 3 C (360 mA g(-1)), 5 C, and 10 C, respec...

| Zusammenfassung: | LiMn2O4 yolk-shell powders with a distinctive filled-core@void@shell configuration are prepared by a spray pyrolysis process. The yolk-shell powders have discharge capacities of 127, 120, and 115 mA h g(-1) after 200 cycles, even at high current densities of 3 C (360 mA g(-1)), 5 C, and 10 C, respectively. |
