Nickel, cobalt and manganese lithium chemical analysis
Part 1: Determination of the total amount of nickel, cobalt and manganese
EDTA titration
1 Scope
YS/T 1006 This section specifies the method for determination of lithium ion battery cathode material of nickel, cobalt and manganese lithium nickel cobalt manganese total.
This section applies to the determination of lithium ion battery cathode material nickel-cobalt-nickel-manganese, cobalt and manganese in the total amount of lithium. Determination of the range of 57.00% ~
61.00%.
2 Method summary
Sample was dissolved with hydrochloric acid at pH 9-10 alkaline solution to purple uric acid amine as indicator, titration with EDTA standard solution titration
To purple as the end point. Calculate the total amount of nickel, cobalt and manganese in accordance with the volume of EDTA standard titration solution consumed.
3 Reagents
Unless otherwise indicated in the analysis using only recognized as analytical reagents and meet two or more of water.
3.1 purple uric acid amine indicator: Take 0.4g Purple uric acid amine, add 50g potassium thoroughly ground in a mortar into a fine powder.
3.2 hydrochloride (11).
3.3 ammonia - ammonium chloride buffer solution pH value of 9 to 10: Weigh 54.5g of ammonium chloride dissolved in water and added to 200mL concentrated aqueous ammonia diluted with water
To 1000mL, and mix.
3.4 cobalt standard solution: Weigh 1.0000g of cobalt metal (mass fraction ≥99.99%) in 400mL beaker, add 50mL of hydrochloric acid (3.2),
After the dissolution of hypothermia moved 1000mL volumetric flask, dilute with water to volume, and mix this solution 1mL containing 1.0mg of cobalt.
3.5 disodium edetate (EDTA) standard titration solution (0.01mol/L).
3.5.1 preparation: Weigh 3.72g disodium edetate in 400mL beaker, add water, heat gently to dissolve completely cooled to room temperature and transferred to
1000mL volumetric flask, dilute with water to volume, and mix.
3.5.2 Calibration: Pipette 15.00mL cobalt standard solution (3.4) in 250mL flask, add 50mL water, add 10mL ammonia - chlorine
Ammonium buffer solution (3.3) and about 0.1g Purple uric acid amine indicator (3.1), titration with EDTA standard solution (3.5) titrated to purple.
According to equation (1) to calculate the actual concentration of EDTA standard titration solution:
c = ρ
× 10-3 × V1
58.933 × V2 × 10-3
(1)
Where:
The actual concentration c --- EDTA standard titration solution, expressed in moles per liter (mol/L);
Mass concentration ρ --- cobalt standard solution, in milligrams per milliliter (mg/mL);
Pipette Vl --- cobalt standard solution volume in milliliters (mL of);
58.933 --- cobalt molar mass in grams per mole (g/mol);
Volume of EDTA standard titration solution V2 --- titration cobalt standard solution consumed in milliliters (mL).
When the average of the three poor titration volume is within the range of 0.10mL, take three calibration results, or re-calibration.
