Sodium batteries begin to be used in energy storage projects

Are sodium-ion batteries scalable for large-scale energy storage?

Full-scale analysis reveals critical future directions for scalable SIB technology. Data-driven insights support SIB advancement for large-scale energy storage use. Sodium-ion batteries (SIBs) are emerging as a scalable, cost-effective alternative to lithium-based technologies for large-scale energy storage.

What is a sodium ion energy storage system?

The sodium-ion energy storage platform has been designed to overcome long-standing limitations of traditional lead-acid-based backup systems by offering up to 2-3 times longer life, significantly reducing operational costs and downtime. The storage system comes in 3.5Kw, 5Kw, and 10Kw models with in-built batteries.

Is sodium a good battery material?

It’s an Earth-abundant and cost-effective material with wide availability that supports the development of scalable and affordable battery systems, particularly for stationary applications like grid storage. However, sodium’s unique chemistry introduces challenges, particularly at the interface where the sodium anode meets the solid electrolyte.

Can solid-state sodium batteries tap all their energy capacity?

This proof-of-concept aims to show that solid-state sodium batteries can consistently tap nearly their entire theoretical energy capacity, cycle after cycle. “We’re starting with small-scale cells to show that these ideas work,” Weller said.
