Sodium-ion battery cost

What is a sodium ion battery?

Overall, we provide a broad and interdisciplinary perspective on modern batteries and future directions for this field, with a focus on sodium-ion batteries. Sodium-ion batteries are an appealing alternative to lithium-ion batteries because they use raw materials that are less expensive, more abundant and less toxic.

Could sodium ion batteries lower the cost of EV batteries?

CATL has three groundbreaking EV batteries but the most important is Sodium ion batteries that could lower the cost of batteries. Chinese engineers at CATL have begun mass-producing sodium-ion cells at their new 30GWh facility in Fujian province. Chery and BYD will start using them in a few months.

Are sodium ion batteries a viable alternative to lithium-ion?

Sodium-ion batteries, developed by CATL, are a sustainable alternative to lithium-ion technology. They offer lower costs, inherent safety, and suitability for EVs and renewable energy systems. With a potential cost reduction to $10/kWh, sodium-ion batteries use sodium's abundance and safety to address energy storage challenges.

How much does a sodium carbonate EV battery cost?

Sodium carbonate costs $200/ton versus lithium carbonate’s $15,000/ton (2025 prices). CATL’s new Naxtra sodium-ion “salt” EV battery costs just $10–$19/kWh – about one-tenth of current lithium-ion prices (~$100–$115/kWh).
