Finnish startup Donut Lab has recently undergone rigorous testing to evaluate the capabilities of its solid-state battery technology. The latest examination, conducted by the state-owned VTT Technical Research Centre of Finland, focused on the battery’s performance under extreme heat conditions.
The tests revealed that Donut Lab’s solid-state battery not only maintained its energy discharge at temperatures as high as 100 degrees Celsius (212 degrees Fahrenheit) but actually exhibited an increase in capacity. The 3.6V/26 Amp-hour battery demonstrated impressive results, delivering 110.5% of its room-temperature capacity at 80 degrees Celsius and 107.1% at 100 degrees Celsius.
Despite the challenging conditions, the solid-state battery continued to function effectively, showcasing its resilience and efficiency even in high-temperature environments. However, the extreme heat led to the loss of the physical vacuum seal on the battery pouch.
This successful testing highlights the potential of Donut Lab’s solid-state battery technology to revolutionize energy storage solutions, particularly in demanding applications where traditional lithium-ion batteries may struggle. The ability of the battery to perform optimally under extreme heat conditions opens up new possibilities for various industries, including transportation and renewable energy.
