This white paper provides a comprehensive analysis of the solid-state battery (SSB) landscape in 2024, offering insights into technological progress, market dynamics, and industrialization challenges. As global electric vehicle (EV) adoption grows but falls short of initial forecasts, the need for advanced battery technologies has become more pressing. Solid-state batteries are positioned as a key solution, promising higher energy densities, enhanced safety, and improved performance—particularly through the use of lithium metal and silicon anodes.

The paper categorizes the evolving types of SSB technologies—ranging from semi-solid to fully solid-state systems—and evaluates key materials like polymer, oxide, and sulfide-based solid-state electrolytes. It highlights how market expectations have shifted toward tangible full-cell performance data, forcing technology developers to demonstrate scalable, safe, and cost-effective prototypes.

Drawing comparisons between conventional Li-ion innovations and emerging SSBs, the report outlines the technical, manufacturing, and cost challenges associated with scaling SSBs. It also discusses regional efforts, with Asian countries making strong governmental investments, while Western players face increasing pressure to keep pace.

While the near-term adoption of SSBs is expected in premium EVs, aviation, and niche sectors, broader market penetration will depend on overcoming cost and manufacturability hurdles. The paper concludes that although SSBs are not a drop-in solution, they hold significant promise for redefining next-generation energy storage—provided the right industrial and technological frameworks are established.
