Announcement date: 14 September 2026 · Development and validation

Keep the stage visible
The source is a company announcement. It supports a development milestone; it does not provide an independently verified commercial production total. The temperature claim should remain attributed to the partners and should not be applied to every sodium-ion cell.
Questions for an application review
Ask for the tested cell model, conditioning procedure, power demand and pass criteria. For supply-chain tracking, distinguish successful validation from equipment readiness, qualified output and customer deliveries. These are useful follow-up fields for evaluating progress from testing into manufacturing.
