3D hybrid, compact, all-solid-state micro-capacitor for high-voltage and fast-charge electronics – MEMPACAP

Submission summary

The MEMPACAP project (48 months) proposes to fabricate compact and encapsulated fast-charge storage micro-sources with high storage capacity, operating in a wide temperature range (-50 to 150°C) and delivering a cell voltage that can be modulated from 10 to 50 volts. To reach this goal, this micro-source will combine a metal-type electrode with a large developed surface area, covered with a dielectric film, with a (pseudo)capacitive electrode to form a hybrid micro-capacitor. The ionic conduction will be achieved by a solid electrolyte (ionogel technology) in its most advanced version. The capacitance of a flat metal/dielectric electrode being low, it will be exacerbated by the use of a 3D hierarchical scaffold with a high specific surface on which the electrode materials (metal and insulator) will be deposited. The second (pseudo)capacitive electrode will be deposited on the back side of a hermetic cap. The application fields are numerous: powering sensors in the automobile industry, implanted defibrillators for the medical sector, energy sources for radar and power lasers, for aerospace and military applications. This collaborative project brings together 4 laboratories (IEMN, UCCS, IMN, CIRIMAT) with complementary skills.
