Synthesis of Double-Shelled LiMn2O4 Hollow Microspheres with Enhanced Electrochemical Performance for Lithium Ion Batteries

open access: yesInternational Journal of Electrochemical Science, 2013
Double-shelled LiMn2O4 hollow microspheres have been prepared from hydrothermally synthesized urchin-like α-MnO2 spheres. A large hollow interior and broad gap between exterior and interior shells are clearly observed within the hollow microspheres ...

Graphite Co‐Intercalation Chemistry in Sodium‐Ion Batteries

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Traditional intercalation chemistry in lithium‐ion batteries cannot allow sodium storage in graphite. The co‐intercalation chemistry changes the situation. It enables reversible and ultrafast sodium storage in graphite. Revisiting challenges and summarizing recent advances are of significant importance to exploit the full potential of graphite in ...
