This Dodge Charger EV Prototype Packs An Experimental Semi-Solid-State Battery

Dodge parent Stellantis is exploring the viability of semi-solid-state batteries with real-world testing. The test mule: A Charger EV.

Why this matters
Why now

Automakers are intensely focused on competitive advantages in EV technology, with battery chemistry being a key differentiator and a race to extend range and reduce costs.

Why it’s important

Semi-solid-state and solid-state batteries promise significant improvements in energy density, safety, and charging speed, which are critical for mass EV adoption and market leadership.

What changes

The deployment of semi-solid-state batteries in real-world testing indicates a maturation of the technology, moving it closer to commercialization and potentially reshaping the EV performance landscape.

Winners
  • · Stellantis
  • · Semi-solid-state battery manufacturers
  • · Electric vehicle consumers
Losers
  • · Traditional lithium-ion battery manufacturers
  • · Companies slow to adopt advanced battery technologies
Second-order effects
Direct

Successful semi-solid-state battery integration could lead to a new generation of EVs with superior performance characteristics.

Second

Increased adoption of these batteries may drive down costs and accelerate the transition away from fossil fuel vehicles globally.

Third
