TL;DR: In this paper, the storage mechanism of soft carbon anodes has been investigated and it has been shown that sodium ions intercalate into graphenic layers, leading to an irreversible quasi-plateau at ∼ 0.5 V versus Na+/Na as well as an irreversible expansion seen by in situ transmission electron microscopy and X-ray diffraction.

Synthesis of micro- and mesoporous carbon spheres for supercapacitor electrode
TL;DR: In this article, micro-and mesoporous carbon spheres (MMCSs) are synthesized by the polymerization of colloidal silica-entrapped resorcinol/formaldehyde in the presence of ammonia as catalyst, followed by carbonization, sodium hydroxide (NaOH) etching to remove silica template, and potassium hydroxides (KOH) activation.
