Description:
Donut Lab, a Finnish company, recently presented what they claim is a revolutionary solid state battery for electric vehicles. The promises sound incredible:
• 400 Wh/kg energy density
• 100,000 charging cycles
• Full charge in 5 minutes
If true, this could completely change the future of electric cars and EV charging.
But after the first independent lab tests and analysis from several battery experts, the excitement is fading. The data that was published does not seem to show anything significantly better than a modern lithium-ion battery.
In this video I go through the available test data and the expert analysis:
What the charging curves reveal
Why the test results look similar to lithium-ion batteries
The problem with testing only one single battery cell
Questions about cooling requirements and efficiency
Why the claimed 100,000 cycle lifespan may not match the measured data
Solid state batteries have been promised for years as the next big breakthrough for EVs. But does Donut Lab actually have something special – or is this just another overhyped battery claim?
Let’s break down the numbers.
