Claim 6:
7. An electrochemical cell comprising:
an anode separated from a cathode by a liquid-permeable separator; and
an electrolyte disposed generally throughout the anode and the cathode;
wherein the anode comprises a first current collector substrate and an active material composite layered onto the first current collector substrate, wherein the active material composite comprises:
a first layer adjacent the first current collector substrate and including a plurality of first active material particles adhered together by a first binder, the first active material particles comprising a mixture of graphitic carbon and hard carbon configured to have a first free energy to lithiate per mole, wherein the first layer further comprises a conductive additive different from the plurality of first active material particles; and
a second layer adjacent the liquid-permeable separator and including a plurality of second active material particles configured to have a second free energy to lithiate per mole;

wherein the first free energy to lithiate per mole is less than the second free energy to lithiate per mole.
