Abstract
Solid-state batteries (SSBs) are widely regarded as a cornerstone technology for next-generation energy storage, offering intrinsic safety advantages and the potential for substantially higher energy densities than conventional liquid-electrolyte lithium-ion batteries. Despite intense global research activity, progress toward commercialization has been uneven, largely due to persistent challenges associated with ion transport, interfacial instability, and mechanical degradation within solid-state architectures. This systematic review and meta-analysis synthesizes experimental evidence across oxide-, sulfide-, and polymer-based solid-state electrolyte systems to identify robust performance trends and critical design bottlenecks. Emphasis is placed on electrolyte classification, lithium-metal and alternative high-capacity anodes, interfacial phenomena, and emerging strategies for interface stabilization, including artificial interphases, electropolymerized coatings, and three-dimensional electrode architectures. Quantitative meta-analytical comparisons of reported energy density, cycling stability, and interfacial resistance reveal that interfacial engineering exerts a stronger influence on practical performance than electrolyte chemistry alone. In parallel, the review evaluates the growing role of sustainability-driven materials, particularly biomass-derived carbons, as low-cost and environmentally responsible components in solid-state systems. Advances in computational modeling and multiscale simulations are also examined for their contribution to predictive materials design and accelerated optimization. By integrating materials science, interface mechanics, sustainability considerations, and quantitative evidence synthesis, this review provides a holistic assessment of the current state of solid-state battery research. The findings highlight that the transition from liquid to solid electrolytes represents not a simple materials substitution, but a systemic redesign of battery architecture, where interface control emerges as the decisive factor governing safety, performance, and scalability.
