Advances in Automotive Battery Applications

Reliable LIB SOC/SOH prediction is essential for optimizing the LIB usage and operation using onboard controls. However, with the advances and changes in cell material chemistry, the prediction models develop new issues due to additional phenomenon and reactions which evolve. Commercial NMC-Gr/SiO cells were tested at different voltage and SOC ranges and a degradation mapping was developed. Gradual degradation behavior and unusual degradation behavior was studied using data analysis and cell internal resistance mapping. Additionally, data fitting was used to develop parameters for gradual degradation behavior as a means to predict the cell capacity degradation.

The battery accounts for 30% to 50% of the electric vehicle cost. And 75% of that battery value is the chemistry. It is imperative to reduce the cost of the chemistry to make EV accessible to everyone in Europe. At Ampere, we have a plan to reduce the battery cost by 40%. We will be halfway in 2026, and we will get there by late 2028 with our next generation battery chemistries and architecture. In this talk I will share with you at high level what we are doing at Ampere, from a battery chemistry perspective, to reduce the cost of electric cars.

Solid state batteries garner a large amount of attention as the future of next-generation battery chemistries and as a result it can be difficult to separate hype from reality in this important technology. This talk will discuss the status of solid state battery commercialization, important challenges remaining, and technology needs from an automotive OEM perspective.

As advanced materials enable more efficient applications, understanding their structure is paramount. However, the detailed structure of battery materials, for example, often remains unclear despite commercial success.

It will emphasize the need to leverage structural insights to achieve high performance at a lower cost.

Solid-state electrolyte SSE materials hold the key to enabling highly efficient solid-state battery technologies. Thus, the demonstration of SSEs capable of meeting the performance metrics demanded is of paramount importance. Herein, we will provide an update related to progresses being made in the area of SSE material development.

The United States Advanced Battery Consortium LLC (USABC), a subsidiary of USCAR, is a collaborative research organization comprised of technical personnel from Ford, General Motors, and Stellantis. USABC has been pursuing advanced energy storage technologies for electrified vehicles for over 30 years. This talk will highlight recent updates to USABC’s long term battery development targets and provide an overview of expected upcoming funding opportunities for US-based battery suppliers.

The battery market saw a deployment of around 1.7 TWh in 2025. Battery evolution is occurring in many different directions, with each avenue viewed as ‘the next big thing.’ Developments include advancements in LFP chemistry with LMFP, the use of silicon anodes, sodium ion or the emergence of ultra-fast charging technologies. However, solid-state batteries have gained interest for over a decade now.The session will look to address several key questions and will give a broad overview of the market dynamics and how we expect the market to evolve in terms of and next generation battery technologies. 

Solid-state batteries are increasingly viewed as the most promising pathway to achieve safer, higher-performance, and longer-lasting energy storage systems. By replacing flammable liquid electrolytes with solid conductors, they offer the potential for gains in energy density and safety. Recent advances in solid electrolytes—ranging from sulfides with record ionic conductivity to hybrid polymer–ceramic systems with improved flexibility—are expanding the design space for both high-power and high-energy applications. This talk will explore how advances in material science, cell engineering, and manufacturing innovation must converge to unlock the full potential of solid-state batteries across industries.

This presentation explores novel megawatt-scale EV fast-charging stations powered directly from medium-voltage grid based on Loosely-Coupled Resonant Solid-State Transformers without the need for low-frequency transformers. The approach aims to reduce energy loss by 70%, footprint & weight by 50%, and cost by 25% compared to existing SST. It enables flexible and modular deployment and achieves more reliable operation in EV fast-charging stations, AI data-centers, and large-scale MWh energy storage systems. Reliability is considerably improved over existing technology. The technology has been validated in the laboratory and can be commercialized in fast-charging stations, AI-data centers, and MWh ESS within 3-5 years.

Gas detection during thermal runaway in lithium-ion batteries offers a promising method for early detection and safety assessment. Although heat-generating reactions have been extensively studied using techniques like accelerating rate calorimetry (ARC) and differential scanning calorimetry (DSC), correlating these reactions with gas emissions remains challenging. This talk will focus on real-time analysis of gas species generated within battery cells leading up to thermal runaway.

Battery systems have evolved into complex assemblies where the battery cell, while central, is only part of a larger integrated architecture. Battery systems incorporate mechanical structure, thermal management, and advanced BMS, requiring robust integration to deliver safety, reliability, and performance. This presentation will discuss how each subsystem contributes to the overall battery system performance. We will examine current trends, emerging trends, technological advancements, and opportunities for innovation in next-generation systems.
