ELECTRODE MIX, ELECTRODE, AND NON-AQUEOUS ELECTROLYTE SECONDARY BATTERY |
摘要 |
An electrode mixture comprising a lithium nickel manganese composite metal oxide having an average particle diameter of 1 µm or less, an electrically conductive material and an overcharge inhibition material. The electrode mixture in which the overcharge inhibition material is an aromatic compound. The electrode mixture in which the overcharge inhibition material is one or more members selected from the group consisting of an aramid, a polyether, a polysulfone and a polyethersulfone. An electrode comprising the electrode mixture. A nonaqueous electrolyte secondary battery comprising a positive electrode, a negative electrode capable of being doped and dedoped with lithium ions, a separator and a nonaqueous electrolytic solution, wherein the positive electrode is the electrode described above.
