Cathode is the positive electrode of a battery. Popular chemistries use nickel and cobalt to achieve high energy density and specific energy. Lithium iron phosphate (LFP) is becoming common as a lower-cost alternative in energy storage systems (ESS) and mass-market electric vehicles. Lithium ions leave the cathode when charging and return during discharge.
