For example MoSe2, i know you can use Faraday's equation but it does not take into account anything about the intercalaction species such as Li, Ka, Na.
To apply the Faraday's equationit is not only depend on the chemical formula of the material but it also depends on the kind of material ( MoSe2 ) and the kind of storage ions Li, Na or K, where the key point is the electrochemical reaction mechanism and exact number of electrons consumed on this mechanism. For more understanding you can read the following articles
