R.I.P. Our Dry Printed Validation Cell, After 4,412 Cycles
Gone but not forgotten
SAN JOSE, Calif. — It is with heavy hearts that we share the news that our dry processed lithium-ion validation cell (“Cell”), aka our Little Battery That Could, finally expired in the lab of our San Jose headquarters after an extraordinarily long, energetic, and high-performing life.
An icon of performance
Preliminary findings from the post-mortem examination performed by our experts indicate that, after an exceedingly long and vibrant performance, the nickel cobalt manganese (NCM) battery cell recently declined below the minimum 80% charge that is typical for viability in an electric vehicle. A 1Ah test cell cycled at 1C/1C, our Cell had reached an amazing 4,412 cycles when it “crossed the great divide,” an unprecedented milestone in battery viability when using a fully dry process to print the cathode.
Cell is survived by Kavian®, the additive manufacturing platform that gave it life. Cell’s graphite anode combined with its NCM811 cathode, which was fully dry printed using existing chemistry materials. (An October 30, 2025, press release described Cell’s humble origins and illustrious career affirming the reliability of Li-ion battery electrodes dry printed by Kavian without any new materials or optimization.)
Cell received the best possible care in its twilight days. A dedicated materials engineering team monitored Cell closely due to its waning vitality, but no final pings, pips, or beeps were recorded.
Oh Cell, we hardly knew ye, but we are certain you will become an industry icon of performance and longevity among commercially available lithium-ion batteries in EVs and other mass energy storage applications.
A private memorial service is in the planning stage.
