• e is equal to or less than 0.05;
• f is equal to or less than 0.02;
• and
• g is equal to or less than 0.05.
• an anode disposed on an anode current collector;
• a separator positioned between the cathode and the anode;
• and
• an electrolyte configured for carrying ions between the cathode and the anode.

A method for forming a cathode for a battery cell in an electric vehicle battery pack, comprising:

• forming a precursor, the precursor including
• manganese(II) sulfate (MnSO4);
• iron(II) sulfate (FeSO4);
• and
• phosphoric acid (H3PO4);
• adding at least one dopant element to the precursor, wherein the at least one dopant element includes at least one of the following:
• a hydrated mixed metal phosphate compound (HMnFePO4·H2O);
• lithium carbonate (Li2CO3);
• titanium oxide;
• magnesium oxide;
• cobalt oxide;
• yttrium oxide;
• or
• niobium oxide;
• wherein a slurry is formed;
• milling the precursor and the at least one dopant element;
• adding a carbon precursor to the slurry;
• and
• calcinating the slurry to form an active cathode material.
