1. An electrochemical cell, comprising:
a first electrode, comprising:
an ion-conductive layer comprising a plurality of fused particles formed from unfused particles having an original surface, wherein at least a portion of the plurality of fused particles are fused to one another such that at least a portion of the original surface of the unfused particles can no longer be discerned in the plurality of particles fused to one another, wherein the ion-conductive layer further comprises a plurality of unfused particles;
a current collector adjacent to the ion-conductive layer; and
a second electrode comprising lithium.
