Developing effective cooling systems and thermal management strategies tailored to the unique characteristics of SIBs is essential for their successful integration into autonomous vehicles and other navigation applications.

Manufacturing scalability and cost-effectiveness remain hurdles in the commercialization of SIBs. While sodium is more abundant and potentially cheaper than lithium, the production processes for SIBs are not yet as optimized or cost-efficient as those for lithium-ion batteries. Achieving economies of scale and reducing production costs are crucial steps in making SIBs a viable alternative for widespread use in autonomous navigation systems.

Lastly, the integration of SIBs with existing battery management systems (BMS) and power electronics designed for lithium-ion batteries presents a challenge. These systems need to be adapted or redesigned to accommodate the unique characteristics of SIBs, including different voltage profiles, charging protocols, and safety considerations. Developing specialized BMS and power control systems optimized for SIBs is essential for maximizing their performance and ensuring seamless integration into autonomous navigation platforms.
