For instance, the Chevrolet Silverado EV Work Truck, equipped with this new battery, boasts an EPA-rated range of 492 miles on a single charge. It also features one of the fastest charging systems on the market, with a capacity of 350 kW.

How the New Technology Works

The new battery technology builds upon GM’s existing nickel manganese cobalt aluminum oxide (NMCA) batteries, which are known for their impressive range and reliability. By integrating LMR into this system, GM has managed to maintain the same level of performance while reducing the reliance on more expensive materials like nickel and cobalt.

In traditional high-nickel battery cells, the composition is typically around 85% nickel, 10% manganese, and 5% cobalt. In contrast, LMR cells have a different chemical makeup—approximately 35% nickel, 65% manganese, and almost no cobalt. This shift is significant because manganese is not only cheaper but also more abundant than nickel or cobalt. As a result, the overall cost of the battery is significantly reduced.

Additionally, the design of LMR batteries allows for larger cell sizes, which further lowers system costs by minimizing the need for additional connective and structural components in the battery pack. This efficiency contributes to a more cost-effective and sustainable solution for EV manufacturers and consumers alike.

Advancements in Efficiency and Performance

Beyond cost savings, the new LMR battery technology also enhances efficiency and performance. The size and shape of these batteries allow for improved energy management, ensuring that power is delivered more effectively. Specialized coatings applied to the battery cells help maintain voltage levels over time, ensuring consistent performance and extending the lifespan of the battery.

These innovations position GM as a leader in the ongoing evolution of electric vehicle technology. As the company continues to refine and expand its use of LMR batteries, the path toward a more accessible and sustainable electric future becomes clearer.

With continued investment in research and development, the barriers to EV ownership are gradually being dismantled. This progress not only benefits American consumers but also has the potential to influence the global EV market, paving the way for a greener and more efficient transportation system.

EV batteries could offer longer lifespan, increased safety with new Swedish technology

The lifespan of EV batteries has remained a challenging factor for their users. After continuous usage over years, the lifespan of these batteries decreases. But a new experiment offers hope for a longer lifespan of EV batteries.

An AI model developed at Uppsala University could reportedly offer improved safety and longer life for EV batteries. The model provides a much more accurate picture of battery aging.

Batteries in electric vehicles wear out too quickly

Being able to learn more about the life and ageing of batteries will benefit future control systems in electric vehicles. It also shows how important it is to understand what happens inside thebatteries," said Professor Daniel Brandell, who led the study and is in charge of the Angström Advanced Battery Centre atUppsala University.

If we stop looking at them as black boxes that are simply expected to provide power, and instead acquire a detailed picture of the processes, we can manage them so that they stay in good conditionlonger.”

Batteries in electric vehicles wear out too quickly and this is slowing down the electrification of the transport sector.

AI tool extends lifespan

This is a major waste of resources today and is holding back the transformation of the transport sector. To address this issue, the automotive industry is developing software, often based on AI, to optimize battery management and control. The latest tool by Canadian researchers is one of them.

Researchers also revealed that several years of battery testing were behind the study, carried out in collaboration with Aalborg University in Denmark. A database was built by collecting data from numerous very short charging segments. This was then combined with a detailed model of all the different chemical processes taking place inside the battery.

"Altogether, this gives us a very precise picture of the various chemical reactions that result in the battery generating power, but also of how it ages during use," says Wendi Guo, who conducted the study.

ML framework built on digital twin model

Researchers revealed that their work proposes the machine learning (ML) framework built on a digital twin model that links key design parameters to real-world behaviors of graphite/nickel–manganese–cobalt–oxide LiBs under a diverse range of fast charging protocols, depths of discharge, and dynamic discharge profiles representative of applications in Nordic climates.

Published in the Energy and Environmental Science journal, theresearchfocuses on a new framework that infers six key design parameters directly from short charging segments, enabling rapid health prediction within seconds.

Model improves the robustness of health, lifetime predictions

Notably, this approach improves the robustness of health and lifetime predictions by up to 65% and 69%, respectively, compared to baseline multi-layer perceptron and linear regression models, while also outperforming the baseline random forest model, with a training time of 1 second, according to researchers.

The research team also pointed out that the strong physical correlation between capacity variability and three design parameters—solid-state diffusion coefficient, particle radius, and electrode thickness—during fast charging highlights their vital role in determining the degradation pathways.

"The framework can be easily integrated into upstream workflows and battery management systems, enabling end users to customize usage patterns and guiding developers toward improved design strategies," said researchers in the study.

An ultra-thin smart filter can significantly extend EV battery life span

Car manufacturers and others who need light, safe, powerful batteries are eager to adopt lithium-sulfur (Li-S) batteries. Not only do they store more energy, and are safer and faster to charge than today's lithium-ion batteries—they're cheaper to make, too.

It's just that these next-generation wonder batteries have one big problem: They wear out very quickly. The reason is that they suffer from what is called the shuttle effect.

"It's about chemical substances, lithium polysulfides (LPS), that are formed when the battery is in operation. The substances move between the electrodes, the positive anode and the negative cathode, in the battery. It is these substances that cause LiS batteries to degrade quickly, lose capacity and have a short lifespan," said Önder Tekinalp, a postdoctoral fellow at NTNU's Department of Chemical Engineering.

This also explains why this type of battery has not yet moved into our electric cars.

New, thin, smart filter

Tekinalp and his colleagues have developed a super-thin coating with very special properties that can change this. They have patented the coating via a project called HiSep-II. The coating has been given the same name as the project.

Inside a battery there is also a separator. There is a partition between the electrodes, which makes it work effectively and prevents short circuits. When the HiSep II coating is applied on the outside of the wall, it acts as a smart filter.

This new invention could make today's heavy electric vehicle batteries lighter, safer, and increase their range. The researchers behind the technology believe it is also ideal for use in aviation, space travel, drones, and shipping.

Many people working to improve lithium-sulfur batteries focus on pure chemistry in the cathode and electrolytes. The NTNU researchers have thus focused on the partition instead.

"The coating blocks the harmful chemical substances and allows useful lithium ions to pass freely," Tekinalp said.

Slimmer, lighter battery pack

The lifespan of a battery is often measured in charge cycles. One cycle is the same as one full charge and one full discharge. The tests from the lab at Gløshaugen show that lithium-sulfur batteries equipped with HiSep-II can increase the number of charging cycles from 200 to 1,000. That lengthens the battery life by a factor of five.

The battery pack in an electric car consists of many parts. The researchers say the patented technology can reduce an 800-volt battery pack by more than 200 kilograms. That, in turn, means significantly better efficiency and a much longer range. The fact that this next generation of electric car batteries are made from sulfur, which is abundant, also makes them cheap to produce.

Real alternative for electric cars

Tekinalp believes their research is a breakthrough, which will contribute to making lithium-sulfur batteries a real alternative for electric vehicles.

"Although HiSep-II has not yet been used in electric cars, we have shown that it can handle the shuttle effect. It has been the major brake on commercial exploitation—until now," says the researcher.

HiSep-II patented the separator in 2023, and is working with NTNU Technology Transfer (TTO) to bring it to the market.

"The goal is to scale up the technology and license it to an industrial partner so that it can be used in everything from electric cars to storage of green energy," says Kristina Nydal, a business developer at TTO.

She believes Hi-Sep II can contribute to increased battery safety, and says that the technology is ideal for use in areas such as aviation, aerospace, electric cars, drones, and maritime transport.

"It is also an attractive and cost-effective alternative for storing energy. Especially where longevity and stability are crucial factors," she said.

The production process is environmentally friendly, the technology is designed to be easily scalable, and it can work with today's lithium-based batteries.

Scaling up and testing

Before they are ready for the market, external players must test the technology. The filter must be built into Li-S batteries, and its performance must be checked and confirmed by an independent third party. Documenting that the technology is reliable and stable in the long term is crucial. They must also ensure that the new smart filter can be produced safely, economically and with consistent quality.

Patent processes are costly and should be adapted to the industrial use of the technology. TTO is now looking for an interested licensee who can finance further patenting and commercialization and participate in the planned tests.

When asked how the technology differs from sulfur batteries, Tekinalp replied, "Many Li-S breakthroughs focus on improving cathode materials or electrolytes. The HiSep-II targets only the separator, or filter. It is a simpler, more scalable solution without using complex materials. The production process is environmentally friendly, the technology is designed to be easily scaled up, and it can work together with today's lithium-based batteries."
