Donut Lab has released an elemental analysis confirming that its battery technology does not contain lithium or sodium, refuting ongoing conspiracy theories.
Intertek Labs analyzed Donut Lab's solid-state battery components, finding low lithium and sodium levels, while questions persist regarding the battery's composition and market readiness.
Finnish startup Donut Lab is facing scrutiny over its solid-state battery claims following a limited laboratory report that failed to clarify the company's core technology and production timeline.
Donut Lab claims its battery is free of lithium and sodium, but the limited scope of the independent test and the lack of production vehicles raise questions about the startup's technology.
Comparative testing confirms that Donut Lab’s DL2 battery is not an NMC-type cell, as it remains stable under high-temperature conditions that cause NMC batteries to inflate and decompose.
Donut Lab has revealed performance data for its solid-state battery, achieving 409 Wh/kg energy density and utilizing a low-cost printing manufacturing process.
Donut Lab reported an energy density of 409 Wh/kg for its battery, but the company has failed to meet its Q1 2026 deadline for delivering a production-ready solid-state EV battery.
