Global Molten Salt Battery Market Report and Forecast 2025-2034

Global Molten Salt Battery Market Outlook

The global molten salt battery market size reached a value of approximately USD 1.57 billion in 2024. The market is further projected to grow at a CAGR of 16.50% between 2025 and 2034, reaching a value of USD 6.28 billion by 2034.

Key Trends in the Market

Molten salt batteries are a type of battery system that uses molten salts as electrolytes and offer a high power density and high energy density with a long lifespan. At room temperature, the components of molten salt batteries are solid, due to which they can be stored in an inactive state for extended periods of time. When the molten salt batteries are activated, the electrolytes, cathodes, and anodes separate, and ionic exchange takes place that generates energy.
