  Solid electrolytes are widely considered as the enabler of lithium metal
anodes for safe, durable, and high energy density rechargeable lithium-ion
batteries. Despite the promise, failure mechanisms associated with solid-state
batteries are not well-established, largely due to limited understanding of the
chemomechanical factors governing them. We focus on the recent developments in
understanding solid-state aspects including the effects of mechanical stresses,
constitutive relations, fracture, and void formation, and outline the gaps in
the literature. We also provide an overview of the manufacturing and processing
of solid-state batteries in relation to chemomechanics. The gaps identified
provide concrete directions towards the rational design and development of
failure-resistant solid-state batteries.
