How to remove Li2CO3 in the powder?
« on: October 22, 2015, 03:25:15 AM »
Hi.

I am developing cathode materiala for Li-ion battery.
However, the final cathode material contains around 10000ppm of Li2CO3.
I want to decerease 10000ppm to lower than 2000ppm. By washing the cathode material in CO2 purged water, it will be around 3000-4000ppm.

However, CO2 purged water is not good for the material, so I am finding another method.

Do you have any good idea to decrease the contents of Li2CO3?
1. The material is black powder. Black corlor. Density is 2.5g/cc
2. If possible I do not want to wash in solution such as water: Because this material is weak to water or solution. But if the new method is using solution, its ok.
3. The new method must not harmful to human.

Thanks.
