1. An electrochemical device comprising:
an electrochemical cell including a current collector, the current collector including an electrically-conductive material;
an inductor coil configured to generate a magnetic field, the magnetic field configured to induce an eddy current in the current collector to generate heat in the current collector; and
an insulating pouch at least partially enclosing the electrochemical cell, the inductor coil at least partially disposed inside the insulating pouch.
