"Donut Labs' cell claims to be made from cheap and easily available materials, would charge to full in a few minutes and last for hundreds of years. If real, such a device would change the face of the world, which is why plenty of people don't think it is."
"Conventional batteries have improved a lot in the last few decades but remain imperfect in many ways. Cells found in electronics and EVs commonly use liquid or gel polymer as an electrolyte, which can lead to thermal runaway and battery failure."
"Solid state batteries should be lighter and smaller per watt than conventional batteries, providing significant benefits for electric vehicles where weight and size are critical to performance."
Donut Labs, a Finnish-Estonian startup, claims to have created a solid state battery made from inexpensive materials that charges quickly and lasts for centuries. However, skepticism exists regarding the validity of these claims, as the company struggles to provide substantial proof. Solid state batteries are sought after due to their potential to eliminate issues associated with conventional batteries, such as thermal runaway and performance limitations. The industry is moving towards semi-solid batteries, with fully solid state options anticipated soon.
