Batteries based on sodium-ion technology could be made in the US with locally sourced materials.

* Europe's heatwave has increased demand for battery storage solutions, particularly sodium-ion batteries.
* Companies such as Emerald Battery Labs and Peak Energy are working on developing US-based production facilities for sodium-ion cells.
* These companies aim to reduce reliance on China-sourced cells and establish a domestic supply chain for sodium-ion batteries.
* Sodium-ion batteries are seen as a safer alternative to lithium-ion batteries, with reduced fire risk.
* The technology has the potential to enable large-scale energy storage for electricity grids and help distribute renewable energy to data centers.
* US companies believe they can compete with Chinese manufacturers due to growing demand from data centers and other industries.
