Donut Lab solid-state battery shows resilience in damage test

A recent independent test by Donut Lab has shed light on its solid-state battery’s ability to withstand physical damage. The company conducted a deliberate attempt to harm the battery, applying pressure and stress while it was still connected to a charger. Notably, despite minor deformation of the pouch surrounding the cell, the battery managed to maintain some level of functionality. The test was designed to simulate real-world scenarios where batteries may be subjected to physical trauma, such as being dropped or crushed. Donut Lab’s researchers at Finland’s VTT Technical Research Centre had previously conducted extensive testing on the battery under extreme heat conditions, which resulted in a loss of vacuum seal and some thermal runaway. However, the latest test revealed that the solid-state battery could endure damage without severe consequences. While the results are promising, it is essential to acknowledge that the battery still showed signs of degradation after being subjected to physical stress. Nevertheless, Donut Lab views this as a significant step forward in demonstrating the potential of its technology and can be seen as a victory for the company’s ambitious goals.
