An energy storage device includes a first electrode comprising a first material and a second electrode comprising a second material, at least a portion of the first and second materials forming an interpenetrating network when dispersed in an electrolyte, the electrolyte, the first material and the second material are selected so that the first and second materials exert a repelling force on each other when combined. An electrochemical device, includes a first electrode in electrical communication with a first current collector; a second electrode in electrical communication with a second current collector; and an ionically conductive medium in ionic contact with said first and second electrodes, wherein at least a portion of the first and second electrodes form an interpenetrating network and wherein at least one of the first and second electrodes comprises an electrode structure providing two or more pathways to its current collector.

1. A method for producing a bipolar device comprising: providing a layered or porous first electrode comprising a first electroactive material;providing a mixture of a medium and particles of a second type comprising a second electroactive material, wherein the medium is electronically-insulating and ionically-conductive;contacting the mixture with the layered or porous electrode, wherein the first electroactive material and the particles of the second type exert a repelling force on one another; andsegregating at least a portion of the particles of the second type into a second spatial region that is essentially free of electronic contact with the first electrode to form a network of electronically-connected particles. 2. The method of claim 1, wherein the particles of the second type are self-attractive in the medium. 3. The method of claim 1, further comprising providing a current collector in electronic communication with the network. 4. The method of claim 1, wherein the particles of the second type comprise at least one of LiCoO2, LiCoO2 doped with Mg, LiNiO2, LiMn2O4, LiMnO2, LiMnO2 doped with Al, Li(Fe,Mn)PO4, LiFePO4, LiFePO4 doped with one or more of Mg, Al, Ti, Nb, Ta, Zr, or W, Li2Fe2(SO4)3, V2O5, V6O11, C, amorphous carbon, graphite, mesocarbon microbeads, Li, LiAl, Li9Al4, Li3Al; Zn, LiZn, Ag, LiAg, Li10Ag3, B, Li5B4, Li7B6, Ge, Si, Li12Si7, Li21Si8, Li13Si4, Li21Si5, Sn, Li5Sn2, Li13Sn5, Li7Sn2, Li22Sn5, Sb, Li2Sb, Li3Sb, Bi, LiBi, Li3Bi, SnO2, SnO, MnO, Mn2O3, MnO2, Mn3O4, CoO, NiO, FeO, LiFe2O4, TiO2, LiTi2O4, glass with a Sn—B—P—O compound and mesocarbon microbeads coated with at least one of poly(o-methoxyaniline), poly(3-octylthiophene), and poly(vinylidene fluoride). 5. The method of claim 1, wherein the medium comprises at least one of poly(ethylene oxide), poly(styrene), poly(acrylonitrile), poly(vinylidene fluoride), diiodomethane, 1,3-diiodopropane, N,N-dimethylformamide, dimethylpropylene urea, ethylene carbonate, diethylene carbonate, dimethyl carbonate, propylene carbonate, a block copolymer lithium electrolyte doped with a lithium salt, glass with at least one of LiI, LiF, LiCl, Li2O—B2O3—Bi2O3, Li2O—B2O3—P2O5 and Li2O—B2O3—PbO and a sol or gel of the oxides or hydroxides of Ti, Zr, Pb, or Bi, in a fluid state, in a suspension, in a solution, or in a melt state. 6. The method of claim 1, wherein the medium comprises a polymeric material or a precursor thereto, in a fluid state, in a suspension, in a solution, or in a melt state. 7. The method of claim 1, wherein the bipolar device is a battery.
