The team set out to determine how well Donut Lab&rsquo;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&rsquo;s solid-state battery still discharge energy under conditions of up to 100 degrees Celsius (212 degrees Fahrenheit), it actually gains capacity. <\/p>\n<p> \u2026<\/p>\n<p><a href=\"https:\/\/www.theverge.com\/transportation\/887552\/donut-lab-solid-state-battery-extreme-heat-test\" target=\"_blank\" rel=\"noopener\">Read the full story at The Verge.<\/a><\/p>","protected":false},"excerpt":{"rendered":"<p>Finnish startup Donut Lab is out to prove that its solid-state battery is all that it claims to be.
