Abstract
The invention belongs to the technical field of a metal oxide nanometer material and a lithium ion battery, and particularly relates to a method for fast preparing a nanometer spinel type lithium nickel manganate material by a combustion method. Particularly, lithium acetate, nickel acetate and manganese acetate solids are sequentially and respectively weighed and are put into a crucible; the nickel salt is put into a middle layer; heating is performed, so that the materials are molten to a boiling state; natural and uniform mixing is performed until the combustion reaction occurs; the cooling is performed to obtain a combustion product; then, the combustion product is subjected to roasting and heat insulation; cooling is performed to obtain a nanometer spinel type lithium nickel manganate LiNi<0.05>Mn<1.95>O4 material. The method for fast preparing the nanometer spinel type lithium nickel manganate material by the combustion method has the characteristics that the operation is simple; the synthesis speed is high; the cost is low; the scaled production can be easily realized.
Description
technical field [0001] The invention belongs to the technical field of metal oxide nanometer materials and lithium ion batteries, and in particular relates to the rapid preparation of nano spinel lithium nickel manganese oxide materials by a combustion method. The particle size of spinel-type lithium nickel manganese oxide is 50 nm~90 nm, with good uniformity and crystallinity. It has a spinel-type octahedral structure, which is conducive to the promotion of industrial technology of the product. Background technique [0002] At present, the commercially available lithium-ion battery cathode material LiCoO 2 、LiNi 0.5 mn 1.5 o 4 、LiNi 1 / 3 mn 1 / 3 co 1 / 3 o 2 They are all synthesized by high-temperature solid-state reaction method, and the raw materials used are Co, Ni, Mn oxides and Li 2 CO 3 , LiOH powder, the powder particle size is 5~10 μm, there are problems such as uneven mixing of raw material powder, resulting in poor composition and particle size uniformity of ...
