While sodium is more abundant in nature compared to lithium, the larger size of sodium ions presents challenges in designing batteries that can efficiently accommodate them. Lithium batteries therefore is a preferred choice for applications demanding minimal size and weight.

Energy density, a critical factor in battery performance, differentiates the two types further. Lithium-ion batteries have a higher energy density, enabling them to store more energy in a given volume. Consequently, they excel in devices where maximizing energy storage within limited space is crucial, such as laptops and smartphones. Sodium-ion batteries may have lower energy density due to the inherent characteristics of sodium ions, limiting their modern-day applications.
