The relationship between lithium battery energy storage and sodium battery energy storage

Are sodium ion batteries better than lithium-ion?

Lower Energy Density: Sodium-ion batteries still lag behind lithium-ion batteries in terms of energy density, making them less suitable for high-energy applications. Shorter Cycle Life: Although improvements are being made, sodium-ion batteries typically have a shorter cycle life compared to their lithium-ion counterparts.

How much power does a lithium ion battery deliver?

Lithium-ion batteries can deliver specific power of up to 5,000 W/kg, while sodium-ion batteries typically have a specific power of around 500 W/kg. Finally, the energy efficiency of lithium-ion batteries is typically higher than that of sodium-ion batteries.

What is the energy density of a lithium ion battery?

The energy density of lithium-ion batteries ranges from 100 to 265 Wh/kg, while the energy density of sodium-ion batteries ranges from 80 to 150 Wh/kg. This means that lithium-ion batteries are more suitable for high-energy applications, where a high energy density is required.

Why are lithium-ion batteries so popular?

Since then, lithium-ion batteries have become the standard for portable electronics, electric vehicles, and renewable energy storage due to their high energy density, long cycle life, and relatively low self-discharge rates. Continued lithium-ion technology advancements have further cemented their dominance in the battery market.

Are lithium ion batteries energy efficient?

Lithium-ion batteries can have an energy efficiency of up to 95%, while the energy efficiency of sodium-ion batteries typically ranges from 80 to 90%.LIBs have a high energy density and can provide a high power output, which makes them suitable for use in electric vehicles and grid-scale energy storage systems.

Are Na ion batteries more energy efficient than Li-ion?

However, per the Global EV Outlook 2023 by the International Energy Agency (IEA), Na-ion batteries currently do not offer the same energy density as Li-ion. With energy densities ranging from 75 -160 Wh/kg for sodium-ion batteries compared to 120-260 Wh/kg for lithium-ion, there exists a disparity in energy storage capacity.
