Donut Lab’s solid-state battery can handle the (extreme) heat, test says
TL;DR
Donut Lab's solid-state battery was tested by VTT in Finland and showed it can discharge energy at up to 100°C, even gaining capacity under extreme heat, unlike traditional lithium-ion batteries.
Finnish startup Donut Lab is out to prove that its solid-state battery is all that it claims to be. Last week, the test was about fast charging. This week is where things get hot.
Like the first test, this one was also conducted by state-owned VTT Technical Research Centre of Finland. The team set out to determine how well Donut Lab's cells held up under extreme heat, which has been known to adversely affect traditional lithium-ion batteries. The results show that not only can the Finnish startup's solid-state battery still discharge energy under conditions of up to 100 degrees Celsius (212 degrees Fahrenheit), it actually gains capacity.
