In this article, the results show that the can adsorb onto the powder to provide an electrosteric stabilization in aqueous suspensions, but LA132 does not show such function.
To simultaneously obtain a well-dispersed and a electrode with a better electrochemical property, the appropriate amount of is about based upon weight.
Here is the article information for your reference,
