What sets Altris
sodium-ion apart.
01
No critical minerals – ever.
No cobalt, copper, lithium, nickel, or conflict minerals.
02
0V storage.
Shipped and stored at zero volt. Long shelf life, simple stockpiling.
03
Low cradle-to-gate CO2eq footprint relative to LFP and NMC.
Driven by water-based electrode processing, abundant raw materials, and short transport legs.
04
Non-Dangerous Goods (Class 9 Exempt).
Simplified logistics; no hazmat surcharges or restricted transport modes.
05
Water-based electrode manufacturing.
No NMP or toxic solvents – friendlier on people, planet, and permit.
