A meta-solid-state battery includes a first layer disposed on a first current collector, a second layer disposed on a second current collector, and third layer disposed between the first layer and the second layer. The first layer and the second layer are the cathode and anode electrodes. The third layer includes a first meta-solid-state electrolyte material. Each of the cathode and anode electrodes contain: an active material in an amount ranging from approximately 70% to 99.98% by weight, a carbon additive in an amount ranging from approximately 0.010% to 20% by weight, and a second meta-solid-state electrolyte material in an amount ranging from approximately 0.010% to 10% by weight. The first and second meta-solid-state electrolyte material include a gel polymer.

An electrical and thermal conductive paste composition includes a wetting agent that is arranged as a conduction promoter. Further, a method produces an electrical and thermal conductive paste composition by using a wetting agent as a conduction promoter or a conductivity promoter. The electrical and thermal conductivity of a conductive particle-filled polymer composite is enhanced by using the wetting agent. Capillary forces exerted by the wetting agent cause a particle-filled polymeric suspension to percolate at a decreased volume fraction into a highly conductive network and enhance the conductivity of the composite. Through a jamming gelation technique, the percolation threshold in the particle filled polymer composite is lowered to as low as 3 volume percent. As a result, the electrical and thermal conductivity of the composite is maintained at a significantly lower filler volume fraction with a reduction of particle filler content of up to 50 weight percent.
