During discharge, sodium ions move from the anode to the cathode through the electrolyte. The process reverses during charging.

Key Features:

Voltage: Generally lower than lithium-ion batteries.
Cycle Life: Comparable to lithium, though still under research.
Energy Density: Currently lower, but improving with research, as detailed by ScienceDirect.

Challenges and Innovations

Despite the promise, sodium-ion technology faces several challenges:

Lower Energy Density: Currently less than lithium-ion, affecting size and weight, as noted by Singularity Hub.
Cycle Life: Needs improvement for commercial viability.
Material Degradation: Electrode materials degrade over time.

Innovations:

Advanced Anode Materials: Researchers are exploring alternatives like carbon nanotubes to enhance performance.
Solid Electrolytes: Promising improvements in safety and longevity.
