The provided source offer a comparative analysis of sodium-ion and lithium-ion battery technologies, with one source also introducing solid-state batteries as a future alternative. Both sources discuss the principles, advantages, and disadvantages of these battery types, focusing on key metrics like energy density, cycle life, charging speed, and cost. While the first source, from HuntKey & GreVault, details the current economic landscape where lithium-ion batteries are presently more cost-effective due to recent price drops, the second source, "Battery Technologies 2025: A Comparative Outlook," predicts a future where sodium-ion batteries could achieve a lower cost and offer superior performance in cold conditions by late 2025. Both analyses underscore the application areas for each technology, identifying sodium-ion batteries for low-speed vehicles and specific energy storage needs, while solid-state batteries are presented as a high-performance, high-safety solution for future electric vehicles. Ultimately, the sources highlight the ongoing evolution and competition within the electrochemical energy storage sector, with varying outlooks on the immediate and long-term viability of each battery type.
