Hmm, not quite electric utopia yet
What’s more, many researchers have found that the biggest roadblock is the potential longevity of these new packs. To get very technical, lots of rapid charging can lead to a build-up of dendrites on the lithium electrode.
Like plaque on teeth, this build-up can eventually cause the system to short-circuit and eventually kill the battery.
To make matters worse, there is limited understanding of how to recycle SSBs, meaning a lot of research and funding has to be poured into this area if we want to avoid a pile-up of dead batteries in five to ten years.
