This is clickbait greenwashing imo, if you click-through the website, they still use Zinc and Magnesium for the chemistry/electrodes which isn't much different than lithium. They also claim these metals are natural as they're found in our food and bodies... well so is lithium to some extent.

Sadly we'll need to wait for independent studies. Too many companies claim bio degradability when they barely break down when buried for a long time. https://m.youtube.com/watch?v=SxUkMG2Io4w shows the greenwashing.

These look very good.

I'd be interested to find out how biodegradable the non-paper parts are...

Has any thought been given to what happens if a kid swallows one of these batteries? I'm wondering if they're better or worse than swallowing a typical tiny cell battery.
