12057-17-9 Usage

Health Harzard

Manganese can cause serious lesions of the central nervous system, and lithium has damage to the gastrointestinal tract, kidneys and central nervous system. Use dust masks when there is dust in production, and use industrial gas masks with filters when the concentration is large. The production process should prevent dust. Staff undergo regular medical examinations.

Chemical Properties

monoclinic, a=0.4921 nm, b=0.8526 nm, c=0.9606 nm; prepared by reacting LiOH and γ-ΜnΟ2 in air at 400°C for several days or at 700°C for 24h; used in battery research [ROS91] [RIO92]

Physical properties

Usually spinel phase, working voltage is 3.5~4.3 V, theoretical specific capacity is 148 mA h/g, but the actual is about 110 mA h/g, cathode density is 4.28 g/cm3, and its lithium/manganese molar ratio is 0.45 ~0.5.

Uses

It is used as anode materials of high-performance lithium ion battery.

benefits

LITHIUM MANGANESE OXIDE material is considered to be one of the most promising cathode materials for lithium-ion batteries due to its good stability, good overcharge resistance, low price, environmental friendliness, and good high-current charge-discharge performance.

General Description

This product has been enhanced for energy efficiency.

Synthesis

Using manganese dioxide, manganese carbonate, manganese nitrate or manganese acetate and lithium hydroxide, lithium carbonate or lithium nitrate as raw materials, the composition and content of various materials are accurately analyzed, so that the molar ratio of lithium to manganese is in the range of 0.45 to 0.5. After the ball mill is evenly mixed, it is placed in a mold, pressed into a block shape on a hydraulic press, and placed in a high-temperature sintering furnace for sintering at a temperature of 600-800 °C. 4MnO2+Li2CO3→2LiMn2O4+CO2↑+0.5O24MnCO3+Li2CO3+1.5O2→2LiMn2O4+5CO2↑4MnO2+2LiOH→2LiMn2O4+H2O+0.5O2

Check Digit Verification of cas no

The CAS Registry Mumber 12057-17-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,5 and 7 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 12057-17:
(7*1)+(6*2)+(5*0)+(4*5)+(3*7)+(2*1)+(1*7)=69
69 % 10 = 9
So 12057-17-9 is a valid CAS Registry Number.
