Cost and materials wise, Cathode are a larger portion. Of course, Anodes are of extreme importance as well but Graphite\Silicon are more manageable than Nickel

Cost and materials wise, Cathode are a larger portion. Of course, Anodes are of extreme importance as well but Graphite\Silicon are more manageable than Nickel for example. Anodes are more of an enabler for other things. for instance, anode almost solely dictates the charging rate of the battery. very important parameter for sure.
