Safety: Lead-acid batteries themselves are quite safe in operation, but the use of corrosive acid-based electrolytes hampers their safety. The start-up has demonstrated several operational prototypes: e-bikes, e-scooters, start & stop 12V batteries, 48V batteries. In general, metal-ion batteries tend to be at their most unsafe state at the fully charged state, hence, the requirement for lithium-ion batteries to be transported at a partially charged state is not only cumbersome and more unsafe but also imposes additional costs.

Sodium ion has 10 electrons as sodium atom loses one electron to form sodium ion. Sodium is found in abundance anywhere there is salt water. Sci., 2014, vol. Sodium-ion batteries are also viable means of energy storage, mainly for large-scale electric storage applications, due to the following reasons: (1) low cost of sodium, compared to that of lithium; (2) similar chemistry and intercalation kinetics to that of lithium; (3) the irreversible capacity of carbon anodes in sodium-ion batteries is less than in lithium-ion batteries.

It is expected that with the current rate of rapid progress in the field of sodium-ion batteries, such batteries would be eventually used in applications requiring very high energy density batteries (such as long-range electric vehicles and consumer electronics such as mobile phones and laptops) which are currently served by high cost and high energy density lithium-ion batteries. 143, p. 272. Considering this, there is no reason to assume that NIBs would be inferior to LIBs in terms of energy densities – recent research developments have already indicated several potential cathodes and anodes with performance similar or better than lithium-ion cathodes or anodes. Reliant on Prussian Blue analogues as the cathode and hard carbon as the anode, their sodium-ion batteries can deliver 100 – 130 Wh/kg with good cycling stability over 500 cycles and good rate capability till 10C. Sodium-ion batteries have captured widespread attention for grid-scale energy storage owing to the natural abundance of sodium.
