Linking Porosity to Storage Capacity: Core-Shell Carbon Materials as High-Capacity Anodes for Sodium Ion Batteries

65114 2025 eng poster 0 -- -- -- Linking Porosity to Storage Capacity: Core-Shell Carbon Materials as High-Capacity Anodes for Sodium Ion Batteries Hard carbons (HCs) are currently one of the most promising anode materials for sodium-ion batteries (SIBs). However, the Na storage mechanism remains controversial, leaving the theoretical limits of carbon anodes unclear. To deconvolute the specific capacity from irreversible capacity losses, resulting from the formation of solid electrolyte interphase (SEI), core-shell carbon materials were synthesized. Based on these core-shell materials, an investigation of the storage mechanism of sodium is possible.
