A cell maker moved its long-range line to OC-N90 and OC-E10 and kept 91% capacity after 1,000 cycles in its own tests.

A storage integrator built sodium-ion modules on OC-P7 for a site that drops below −10 °C in winter.

Can you match our current cathode spec?

Send your spec sheet, and we return a matching sample with its lot report within ten working days.

How do you keep moisture out?

Powders are packed in dry rooms below 1% relative humidity and shipped in sealed aluminum bags.

Do you supply safety data sheets?

Every grade ships with an SDS and a lot report that lists composition and moisture.
