Donut Lab’s Solid-State Battery
Donut Lab, a Finnish startup, has made a significant breakthrough in solid-state battery technology. Recently, the company’s battery was tested under extreme heat conditions, and the results were impressive.
Extreme Heat Test
The test, conducted by VTT Technical Research Centre of Finland, involved subjecting the battery to temperatures of up to 100 degrees Celsius (212 degrees Fahrenheit). The results showed that not only could the battery still discharge energy under these conditions, but it actually gained capacity.
At room temperature, the cell delivered 24.9Ah, which served as the benchmark for the other tests. At 80C, the performance improved, delivering 27.5Ah, or about 110.5 percent of its room-temperature capacity. And at 100C, the cell delivered 27.6Ah, or 107.1 percent of its room-temp performance.
Advantages of Solid-State Batteries
Solid-state batteries have the potential to revolutionize the electric vehicle industry. They are made of “dry” conductive material, which can hold more energy without the thermal runaway problems of traditional batteries. This could mean electric vehicles with longer range, shorter charging times, and better performance under extreme conditions.
However, there are still some key questions regarding Donut Lab’s solid-state battery that need to be addressed. For example, the report doesn’t confirm the chemistry of the pack, and the test didn’t address the “dendrite issue,” which can cause electrical shorts.
Meanwhile, the results of this test are promising, and Donut Lab is planning to conduct further independent tests as part of its “I Donut Believe” series. Additionally, the company’s solid-state battery has the potential to improve the efficiency and safety of electric vehicles.
Finally, the development of solid-state batteries is an important step towards a more sustainable transportation system. As the world continues to transition to electric vehicles, the need for more efficient and reliable batteries will only continue to grow.
