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.
My only regret was not buying a more popular model. There are fantastic drop-in battery upgrades for the Prius and leaf, but less popular cars like mine will probably never get upgraded
What car did you end up getting?
Ford cmax, only gets about 20 miles on the stock battery. I don't expect anyone to make a better one, and iirc Ford only sold like 1 model year with an upgraded (20%) battery.
