Electric Vehicle World has long been dreaming about that next big thing in battery tech, the Holy Grail, the one thing that is going to kill all that is hated about EV life: long range anxiety, long charging times and even battery fires. That Holy Grail, in EV’s, is of course solid-state battery technology and for years it always seemed to be some science-fiction fantasy that never quite reached the shelf. That future has now landed in a big way.
Stellantis along with their partner Factorial Energy, have announced that they successfully implemented the next-gen solid-state battery tech into their first EV development car. To really hit home the meaning of what this actually is, not only did they manage to fit the batteries in a car, but that car just happened to be a Dodge Charger Daytona prototype. Now that that first step has been accomplished, Stellantis are about to put the batteries in a full scale road test program and actually put their solid state tech on the road for the first time here in North America.
1. Solid-State Battery Technology Explained
The enthusiasm about solid-state batteries is attributed to a paradigm shift away from lithium-ion designs. Whereas standard lithium-ion batteries employ liquid electrolytes for ion transport between anode and cathode, solid-state batteries use solid electrolytes. While this sounds like a minor difference, this switch from liquid to solid is profoundly disruptive and enables dramatic advancements in energy efficiency, safety, and overall battery performance.
