A contemporary and acute scientific and technological challenge linked to addressing (in part) the UN SDG#7 consists in shifting paradigm from Lithium-ion Battery (unsafe LiB relying on a liquid or a gel electrolyte) to SolidState Battery (SSB featuring (inorganic or polymer) solid-state electrolyte). Beyond electrochemical energy storage and electric transportation key drivers, developing Safe & Sustainable-by-design (SSdD) and higher performance μbatteries are also (very much) awaited to satisfy the increasing demand for miniaturized embarked electronics, e.g. to power Internet of Thing (IoT) objects. To tackle this problem, we innovatively propose to combine a new generation of Self-Healing Polymer Electrolytes (SHPEs designed and synthesized, and characterized at LEPMI) with on-chip Solid-State μBatteries (SSμBs assembled, characterized and cycled at LN2) relying on porosified Silicon (-) electrodes. Performing in-situ and operando advanced X-ray scattering and imaging of SHPEs thin films meltinfiltrated within porous Si (-) electrodes and SSμBs will allow for PoC demonstrations of the high-risk high-gain TRL 1⇒3/4 collaborative research project SHAPE both at the materials and energy storage device levels, respectively.
