Donut Battery’s Test Results Highlight It As A Battery And Not A Supercapacitor
- By MT Bureau
- March 20, 2026
It’s been sometime that Donut Lab has been working on producing a battery that will address the challenging needs of EVs better than other batteries have been able to do. Claiming to be the world’s first solid-state battery ready for production vehicles measured in independent testing conditions, the company has released its third test result that dispels any suspicions that the battery would be a supercapacitor rather than a battery.
The results measure the properties of its solid-state battery, evaluating its ability to retain charge when not in use. Available for download on its site, the third and most recent test follows two other tests that looked at charging speed (the test was conducted by Technology Re) using two passive cooling configurations and evaluation of capacity performance of the battery cell in hot conditions (by the VTT Technical Research Centre of Finland).
The test measuring the battery’s ability to retain charge even when not in use was carried out using a simple research setup. It was connected at room temperature to the research laboratory’s battery tester, which repeatedly measured the cell voltage every 10 seconds. Like the previous test that measured battery performance at very high temperatures, this test also began with a 1C capacity test, demonstrating that the cell was precisely the same as the other test examples.
After the capacity test, the battery cell was charged to approximately 50 percent charge and left connected to the battery tester for ten days. The cell was then discharged to measure the remaining energy capacity. The results show that the battery cell voltage stabilises during the first 10 hours after charging. Over the next nine or so days, the voltage curve continues to stabilise. A capacity test at the end of the test period confirmed that the voltage drop corresponds to the amount of energy in watt-hours.
The Donut Battery behaved in the test exactly as a battery should. If the test had been performed with a supercapacitor, the charge would have fallen linearly much faster during the same time period.
“Since we unveiled the Donut Battery, there has been a lot of speculation and theories about whether it is a supercapacitor. In all its simplicity, this test proves that it is a battery. Supercapacitors charge and discharge quickly, but they also lose their charge quickly when not in use. The Donut Battery behaves like a battery and can maintain a charge for significantly longer,” confirmed Ville Piippo, CTO, Donut Lab.
After the third test mentioned above, Donut Lab has carried out a special test to measure battery performance in a battery pack using the Verge TS Pro motorcycle that charges in less than ten minutes, making it the world's fastest-charging electric motorcycle.
