Abstract. Aiming at the preparation of high electrochemical performance LiNi 1/3 Co 1/3 Mn 1/3 O 2 cathode material for lithium-ion battery, LiNi 1/3 Co 1/3 Mn 1/3 O 2 was prepared with lithium carbonate, nickel (II) oxide, cobalt (II, III) oxide, and manganese dioxide as raw materials by high-temperature ball-milling method. Influence of ball-milling temperature was investigated in this work.
Manganese(IV) oxide is the inorganic compound with the formula MnO 2.This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules.The principal use for MnO 2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery. MnO 2 is also used as a pigment and as a precursor to other manganese ...
