Embodiments described herein relate generally to semi-solid electrodes, and methods of producing the same. In some embodiments, a method of forming a semi-solid electrode can include mixing an active material, a conductive material, and an electrolyte solvent to produce a semi-solid material. The electrolyte solvent is free of electrolyte salt. The method further includes dispensing the semi-solid material onto a current collector and wetting the semi-solid material with an electrolyte solution to form the semi-solid electrode. In some embodiments, the wetting can be via spraying. In some embodiments, the electrolyte salt can have a concentration in the electrolyte solution of at least about 1 M, at least about 2 M, or at least about 3 M. In some embodiments, the solvent can include ethyl methyl carbonate (EMC), ethylene carbonate (EC), propylene carbonate (PC), dimethyl carbonate (DMC), gamma-Butyrolactone (GBL), or any combination thereof.
