Donut Lab, a leading developer of solid-state battery technology, recently underwent an independent test to assess the resilience of its battery under high-stress conditions. The test, conducted by researchers at Finland’s VTT Technical Research Centre, aimed to determine the battery’s performance and safety in challenging scenarios.
Despite sustaining significant damage that led to a notable decrease in energy capacity and efficiency, the solid-state battery did not exhibit hazardous outcomes like fire or thermal runaway typically associated with conventional lithium-ion batteries. During the test, the battery underwent three phases: a baseline test of 5 cycles at 1C, a high-stress test of 50 cycles at 5C, and a final baseline test to measure degradation. The results showed a notable decrease in energy capacity, efficiency, and an increase in thickness post-test.
Donut Lab’s commitment to demonstrating the reliability and safety of its solid-state battery through rigorous testing showcases the potential for advancements in battery technology to address concerns related to battery durability and safety in various applications.
