Or, better yet, they could provide the same range in smaller, lighter vehicles with less resource use.

From the article:

!Moreover, the silicon-gel electrolyte system demonstrated ion conductivity comparable to conventional batteries while achieving a remarkable 40 percent increase in energy density. This represents a significant leap forward in battery technology, offering a practical solution ready for immediate application.!<

So, same energy output, lower weight, similar range. Would be good if this soon becomes a drop in replacement option for older EVs that are nearing EOL on their batteries and require new ones anyway.

I’ve always said that about one of my big reasons for buying an EV several years ago. By the time I’m in need of a replacement battery, it will be better in virtually every way - safer, faster to charge, higher capacity, lighter, and (potentially) cheaper. The first replacement battery might not be much of an improvement, but my 3rd might be light-years ahead.
