Lithium-sulfur batteries for electric cars at knockdown prices: the promise of Stellantis

Electric car news

Have you ever wondered what is still holding back the mass adoption of electric cars? The high price of batteries is often the main reason for this. But promising news could change that. Automotive giant Stellantis is partnering with Zeta Energy to develop revolutionary lithium-sulfur batteries. Their goal? Halve the cost of batteries by the end of the decade.

Technology that defies convention

Lithium-sulfur batteries are not new to the scientific world. They have been known for decades for their exceptional energy density. However, a major obstacle has always hampered their large-scale use: their tendency to degrade quickly. This characteristic made them unsuitable for electric cars, which require constant performance over many years.

It is precisely this challenge that Stellantis and Zeta Energy intend to meet. Their collaboration aims to create a new generation of lithium-sulfur batteries that can rival current lithium-ion batteries in terms of durability, while providing significant benefits:

• 50% more autonomy
• 50% less charging time
• A cost divided by two

These promises could radically transform the market for electric vehicles, making their acquisition and use much more accessible to the general public.

Major environmental and economic benefits

Beyond pure performance, lithium-sulfur batteries have significant ecological advantages. Unlike traditional lithium-ion batteries, they do not require the use of cobalt, graphite, manganese or nickel. These materials, often extracted under controversial conditions, are mainly imported from outside the United States and Europe.

Lithium-sulfur batteries instead use scrap materials, unrefined sulfur and methane. This composition allows for more local and ethical production, considerably reducing the carbon footprint linked to the transport of raw materials. In addition, existing factories can be adapted to produce these new batteries, thus limiting the necessary investments.

Ned Curic, Director of Engineering and Technology at Stellantis, highlights the importance of this innovation: “Our collaboration with Zeta Energy is another step in advancing our electrification strategy, while working to provide clean, safe and affordable vehicles.”

An ambitious but realistic timetable

The development of these revolutionary batteries is already underway. Stellantis and Zeta Energy have established a plan that includes both pre-production and planning for large-scale production by 2030. This timeline may seem long, but it is realistic given the technical challenges ahead and the need to set up an efficient production chain.

To give you an idea of ​​the scale of the project, here is an overview of the key stages:

This step-by-step progression will allow Stellantis to ensure that the technology is fully developed before its massive deployment.

A global commitment to electrification

It is important to note that this lithium-sulfur battery project is only one part of Stellantis' overall electrification strategy. The group is also working on other promising technologies, notably solid electrolyte batteries in partnership with Factorial.

A concrete example of this commitment is the electric Dodge Charger project. A pilot fleet equipped with liquid-free batteries is expected to hit the road from 2026, illustrating Stellantis' desire to explore various technological avenues to meet the challenges of electrification.

This multi-technological approach demonstrates Stellantis' determination to play a leading role in the transition to more sustainable mobility. By diversifying its investments in different battery technologies, the group is giving itself the means to quickly adapt to market developments and technological advances.

A potential impact on the entire automotive market

If Stellantis can deliver on its lithium-sulfur battery promises, the impact on the automotive market could be significant. Electric cars with 800 km of rangerecharging in less than 15 minutes and costing significantly less than today, would become a reality.

This development could drastically accelerate the adoption of electric vehicles, even in regions where charging infrastructure is still limited. In addition, the reduction in costs would make these vehicles accessible to a larger part of the population, thus contributing to the democratization of electric mobility.

You can therefore expect to see, in the years to come, a profound transformation of the automotive landscape. Manufacturers who master these new battery technologies will have a clear competitive advantage. Stellantis, with its investments in lithium-sulfur and solid electrolyte batteries, is clearly positioning itself as a major player in this revolution.

As consumers, you will directly benefit from these technological advances. More efficient, cheaper and more environmentally friendly electric vehicles will soon be within your reach. All that remains is to wait until 2030 to see if Stellantis will deliver on its bold promises.
