"The cells are not violating any law of thermodynamics, Wachsman told me in an email. But the data presented leaves a lot to be desired for many reasons. The insufficient data does not represent real-world usage in automotive applications."
"Researchers say solid-state batteries are a holy grail technology that can unlock superior driving range compared to today's lithium-ion batteries, while substantially reducing charging times and fire risk. At least on paper, the technology has the potential to vanquish range and charging anxieties and unlock broader EV adoption."
"This latest test puts the cell through its paces at high-temperatures of 80 and 100 degrees Celsius (176-212 degrees Fahrenheit), roughly double the maximum operating temperature of conventional lithium-ion batteries. On the surface, the results look promising. But experts urged caution, pointing to data they say is far too thin to mean much."
Donut Lab released its second independent test result for its claimed all-solid-state battery, subjecting a pouch cell to extreme temperatures of 80-100 degrees Celsius (176-212 degrees Fahrenheit), roughly double conventional lithium-ion battery operating temperatures. While initial results appear promising, battery experts urge caution, noting the data is too limited to draw meaningful conclusions. Key claims regarding battery chemistry and energy density remain unverified. Professor Eric Wachsman from the University of Maryland's Materials Science and Engineering department stated the insufficient data does not adequately represent real-world automotive usage. Solid-state batteries are considered a breakthrough technology with potential to increase driving range, reduce charging times, and lower fire risk compared to current lithium-ion batteries.
