Recent progress of nanotechnology in the research framework of all-solid-state batteries

All-Solid-State Batteries (ASSB S ) are considered as one of the mesmerizing technologies for next-generation energy storage with its inherent safe nature. The versatility of nanomaterials can roadmap to the high power/energy storing ASSBs for transferable, bendable, foldable electronics, transportation, and grid-scale energy storage. The most challenging part of designing a comprehensive-nanoscale ASSB assembly, is the down scaling of the particle size of solid electrolyte, upholding its super ionic conductivity. In this context, materials with nanoscale-sized structural features and a large electrochemically active surface can change the paradigm for energy storage that transpire manifold improvement in power and cycle life characteristics. This review primarily provides an outlook on recent progress in the application of the concept of ‘nano’ for energy harvesting in different dwellings of ASSB assemblies. The review also deliberate successful strategies for the exploitation of nanomaterials deployable at the most challenging solid-solid interfaces of ASSBs. Attention is focused on the importance of designing ‘nanoscale particle articulated’, electrode-solid electrolyte interfaces and their aspects in lithium-ion movements. The words ‘nano’ and energy storage entangle as synonyms due to the synergic interactions with each other, which can be envisaged in different dwellings of ASSBs. • Miniaturization and exploration of novel aspects of nano in the framework of research in all-solid-state batteries. • Importance of nano in all solid-state-battery assembly. • Design of nano cathode and micro/nano electrolyte interface in all-solid-state batteries. • New perspective and directions in all-solid-state batteries.
