Solid State High Energy Density Batteries

Imperia Batteries proposes to develop an integrated separator-electrode-electrolyte composite architecture incorporating conductive electrolyte components in a polymer-ceramic composite separator that is directly applied to electrodes, simultaneously improving energy density and safety. This technology will improve safety by reducing the possibility for a cell to short-circuit via electrode misalignment, gas bubble generation, or by melting or shrinking of the separator when exposed to high temperatures. Additionally, the ionic conductivity of the architecture will allow for the reduction/removal of flammable electrolyte components from the cell. These features will protect the cell from common failure mechanisms and reduce risks associated with sympathetic ignition in the event of fire. These safety technologies will be combined with a proven high capacity silicon composite anode. This anode material has been demonstrated to reduce cell weight and increase energy density in a number of cell formats ranging between 1-30+ Ah. Phase I will demonstrate the technology feasibility at the laboratory scale and produce a cell design incorporating the developed technology in order to project impact on performance and cost. The results of Phase I will guide scale-up efforts in Phase II, where multi-Ah prototypes will be developed and produced based on the Phase I cell design.
