| Description |
Using a mixed hydroxy-carbonate (MHC) precursor, homogeneous LiNi1/3Mn1/3Co1/3O2 phase synthesized
through a facile route yielded well dispersed, faceted, edge-blunted polyhedral particles
(w200 nm). These cathode particles revealed high degree of hexagonal ordering favorable for impressive
electrochemical performance viz., high capacity 187 mAh g�1 in Li vs LiNi1/3Mn1/3Co1/3O2 cell, not
fortuitously. Rather, can be clearly attributed to edge-blunted cathode particles that may facilitate
enhanced charge mobility mimicking a process akin to corona discharge predominantly in charge
concentrated regions which contrasts to moderate capacity from spherical particles explainable under
the ambit of shape-drive hither to unknown. Li-ion pouch cell (w500 mAh) fabricated with this activity
enhanced cathode quite rugged enough to endure loads (0.12 Wh, 1.1 Wh), as-demonstrated.
