Sodium-Ion Batteries Benefits

Here are the main benefits of sodium-ion batteries:

• Fast charge/discharge capability

• Low total cost of ownership

• Scalability

• Strong performance

• Superior safety

• Sustainable technology (sodium is the seventh most abundant element on Earth)

As existing lithium reserves are not enough to meet projected levels of demand for the EV market and other sectors, the development of different battery chemistries is gaining momentum.

Unlike the limited availability and uneven distribution of lithium resources, the raw material resources for sodium-ion batteries are abundant and widely distributed across the world.

In addition, high prices of lithium and other battery materials have accelerated the development of the sodium-ion battery as a cheaper and more accessible alternative to the lithium-ion battery (also known as a “Li-ion battery” and “LIB”).

Several cell manufacturers are keen on establishing a Na-ion supply chain for the mass production of Na-ion cells. Production capacity could scale up quickly as Na-ion manufacturing uses existing Li-ion manufacturing infrastructure.

Sodium battery companies have specialized teams to conduct extensive research on the anode and cathode materials of sodium-ion batteries and develop sodium-ion technology for a wide range of applications.

Wrapping Up

The relative abundance and low cost of sodium make it a popular choice for a diverse range of applications, from data centers and electric vehicles to mobile charging piles and large-scale energy storage systems.

For instance, NGK Insulators, Ltd. developed the NAS battery (sodium-sulfur battery) for power grid applications. The NAS battery is a megawatt-level energy storage system that uses sulfur for the positive electrode and sodium for the negative electrode.

Sodium-ion batteries have been used mostly in energy storage applications and two- and three-wheeler vehicles (such as electric scooters). However, recent technology developments are positioning sodium-ion batteries as an efficient and low-cost alternative to lithium-ion chemistries (such as LFP batteries).

A study has shown that a sodium-ion battery scores well over a lithium-ion battery and a solid-state battery in terms of price, safety, and sustainability. Except for energy density and charging time, sodium-ion batteries have stood out as the most efficient and sustainable batteries for electric mobility.

While matching the range of Li-ion counterparts poses a challenge for Na-ion-based EVs, Na-ion-based technology is getting better at catering to the global EV battery energy consumption.

As the battery industry looks for a safe and sustainable alternative to lithium-ion batteries, sodium-ion battery manufacturers are revolutionizing the battery industry landscape with cost-competitive, eco-friendly, energy-efficient, and versatile sodium-ion batteries.
