Aatral: Solar Energy Storage with Sodium-Ion Batteries

This post is a part of the Early Stage Climate Startup series from Climafix 2024

Highlights

Aatral Energy offers sodium-ion batteries that are cheaper, more durable, and more efficient than lithium-ion alternatives.
Their patented NASICON chemistry provides a cost-efficient alternative with a 30% reduction in costs compared to lithium-ion batteries.

Abundant & Safe: Sodium is much more abundant than lithium, resulting in a more sustainable supply chain. Utilizing NASICON chemistry, Aatral’s sodium-ion batteries are fire-safe, have zero discharge capabilities, and are designed to prevent overheating.
Lower Costs: Aatral’s sodium-ion batteries have a 30% cost advantage over lithium-ion batteries, with cell costs ranging between $40-$80 per kWh, compared to $120 per kWh for lithium-ion.

High Costs: Rising raw material prices for lithium and cobalt increase costs, limiting accessibility.
Short Lifespan: Lead-acid batteries degrade quickly. Aatral’s batteries offer a longer lifespan with 90% energy efficiency.

Aatral’s sodium-ion technology has the potential to cut CO₂ emissions by up to 90% per kWh.

Current Target Segments: Aatral Energy targets sectors like solar energy storage for utilities, industrial applications, off-grid energy solutions for remote locations, and grid storage for peak load management.
Future Potential: They plan to supply OEM battery packs, cathodes, and other battery components, as well as provide consulting and R&D services for specialized energy storage projects.

Their patented NASICON chemistry ensures high power density, durability, and fast charging without rare earth metals.
