Stalactites and stalagmites in the battery?

They are considered the 'Holy Grail' of battery research: so-called 'solid-state batteries'. They no longer have a liquid core, as is the case with today's batteries, but consist of a solid material. This leads to several advantages: Among other things, these batteries are more difficult to ignite and can also be manufactured on a miniature scale. Scientists have now turned their attention to the life cycle of such batteries and targeted processes that reduce it. With their findings, more durable solid-state batteries could be realized in the future.
