A solid-state battery is a type of rechargeable battery that uses a solid electrolyte instead of the traditional liquid or gel electrolytes found in conventional lithium-ion batteries.
Unlike conventional lithium-ion batteries that rely on flammable liquid electrolytes prone to leakage degradation, and thermal runaway, solid-state batteries employ solid electrolyte architecture for improved safety and durability.
In fact, the innovative design of solid state batteries minimizes fire risks and enables the safe adoption of lithium metal anodes, which offer exceptional energy storage capacity and lower electrochemical potential. As a result, they achieve higher energy densities, delivering longer driving ranges for electric vehicles and extended battery life for portable electronics.
Despite these advantages, the solid state battery industry faces several technical challenges, such as achieving stable electrolyte-electrode interfaces, addressing mechanical brittleness of materials, and enabling solid-state battery manufacturing scale-up without compromising performance.
Though, continuous innovation in solid electrolyte materials, interface engineering, and hybrid cell designs are steadily advancing the technology toward commercial viability.
For instance, in April 2025, Stellantis and Factorial Energy reached a key milestone in solid state battery development where they successfully validated automotive-sized solid-state battery cells with 375Wh/kg energy density. This is a major step toward the commercial viability of solid-state batteries.
In respect to this, Ned Curic, Stellantis Chief Engineering and Technology Officer commented: “This breakthrough puts us at the forefront of the solid-state revolution, but we are not stopping there. We continue working together to push the boundaries and deliver even more advanced solutions, bringing us closer to lighter, more efficient batteries that reduce costs for our customers.”
