What is a Technology Strategy assessment on sodium batteries?

This technology strategy assessment on sodium batteries, released as part of the Long-Duration Storage Shot, contains the findings from the Storage Innovations (SI) 2030 strategic initiative.

What is a sodium ion battery?

Sodium-ion batteries (NaIBs) were initially developed at roughly the same time as lithium-ion batteries (LIBs) in the 1980s; however, the limitations of charge/discharge rate, cyclability, energy density, and stable voltage profiles made them historically less competitive than their lithium-based counterparts .

Are sodium batteries a good choice for energy storage?

Much of the attraction to sodium (Na) batteries as candidates for large-scale energy storage stems from the fact that as the sixth most abundant element in the Earth’s crust and the fourth most abundant element in the ocean, it is an inexpensive and globally accessible commodity.

Are Na ion batteries a good choice?

Na-ion batteries are not capable of energy densities as high as lithium-ion (Li-ion) and are expected to last fewer cycles. However, they have the potential to be low-cost if produced at scale, coupled with an expectation of a lower risk of thermal runaway. Na-ion batteries can also use many of the same production methods as Li-ion batteries.

Can sodium-based batteries be used for static storage?

Sodium-based batteries could be such an option, particularly for static storage, where cost is a more important factor than weight or performance.

Is peak energy the 'first American venture to advance sodium-ion battery systems?

Peak Energy, claiming to be ‘first American venture to advance globally proven sodium-ion battery systems,’ has raised US$55 million.
