1 Scope
This Part of YS/T 1006 specifies the method for the determination of lithium, nickel,
cobalt, manganese, sodium, magnesium, aluminum, potassium, copper, calcium, iron,
zinc and silicon content in lithium nickel cobalt manganese oxide, which is the cathode
material for lithium ion batteries.
This Part is applicable to the determination of lithium, nickel, cobalt, manganese,
sodium, magnesium, aluminum, potassium, copper, calcium, iron, zinc and silicon
content in lithium nickel cobalt manganese oxide, which is the cathode material for
lithium ion batteries. The range of determination is shown in Table 1.
Table 1 -- Range of Determination
transfer it into a 500 mL volumetric flask. Use water to dilute it to the scale, then, mix it
up. 1 mL of this solution contains 2.0 mg of cobalt.
3.9 Manganese standard stock solution: weigh-take 1.0000 g of pure manganese [w(Mn)
≥ 99.99%] in a beaker; add 50 mL of hydrochloric acid (3.3). Heat it up to dissolve it,
then, remove it and cool it down. Use water to wash the watch glass and the wall of
the beaker; transfer it into a 500 mL volumetric flask. Use water to dilute it to the scale,
then, mix it up. 1 mL of this solution contains 2.0 mg of manganese.
3.10 Sodium standard stock solution: weigh-take 2.5420 g of dried reference sodium
chloride [w(NaCl) ≥ 99.99%] in a beaker; slowly add 100 mL of water and cover the watch
glass. Conduct low-temperature dissolution, then, cool it down. Use water to wash the
watch glass and the wall of the beaker; transfer it into a 1,000 mL volumetric flask. Use
water to dilute it to the scale, then, mix it up; immediately transfer it to a dry plastic
bottle. 1 mL of this solution contains 1.0 mg of sodium.
3.11 Magnesium standard stock solution: weigh-take 1.6580 g of dried magnesium
oxide [w(MgO) ≥ 99.99%] in a beaker; slowly add 50 mL of hydrochloric acid (3.3) and
cover the watch glass. Conduct low-temperature dissolution, then, cool it down. Use
water to wash the watch glass and the wall of the beaker; transfer it into a 1,000 mL
volumetric flask. Use water to dilute it to the scale, then, mix it up. 1 mL of this solution
contains 1.0 mg of magnesium.
3.12 Aluminum standard stock solution: weigh-take 1.0000 g of pure aluminum [w(Al) ≥
99.99%] in a 400 mL beaker; slowly add 50 mL of hydrochloric acid (3.3) and cover the
watch glass. Conduct low-temperature dissolution, then, cool it down. Use water to
wash the watch glass and the wall of the beaker; transfer it into a 1,000 mL volumetric
flask. Use water to dilute it to the scale, then, mix it up. 1 mL of this solution contains
