摘要: In a heuristic endeavor based on electrostatics-dynamics considerations, an attempt has been made to explain the significant enhancement (∼20%) observed in initial capacity for as-synthesized, sharp-edged cathode particles of lithium nickel manganese cobalt oxide, and oxide systems which are considered here as illustrative examples. Also, impressive retention (∼90%) milled blend these, comprising smooth surfaced with cells using respective particles, explained. Enhancement edged can be squarely attributed corona-gain process. On contrary, possible (of near-spherical particles) rationalized terms absence predominant energy drain encountered while shuttling charges across edges as-synthesized process described corona yank
