Next-Generation Cobalt-Free Cathodes – A Prospective Solution to the Battery Industry's Cobalt ProblemDr. Marm Dixit, Oak Ridge National Laboratory
In recent times, the battery research community has been grappling with the growing concern of ensuring sustainability in battery technologies to facilitate the advancement of electric vehicles in the next generation. Over the past decade, the volatile fluctuations in cobalt prices have significantly restricted the supply chains of battery manufacturing industries. This is due to the prevalent use of cobalt-containing cathode materials in mainstream lithium-ion batteries. To ensure a sustainable future for electric vehicles while keeping battery costs low (around $80/kWh), numerous research endeavors have been focused on exploring nickel-rich cathode chemistries with high capacities exceeding 200 mAh/g. Although these nickel-rich compositions do not fully address the sustainability question, they remain the most promising alternatives when considering the performance requirements of modern electric vehicles. In this context, our team has been investigating the development of innovative categories of layered lithium-ion battery cathode materials that do not contain any cobalt. We have systematically studied new cobalt-free nickel-rich battery cathodes with the general formula LiNixM1yM2zO2 (where M1 and M2 represent other metal ions, and x + y + z = 1)[1,2]. Our research focuses on evaluating the performance of these cathodes to identify the most effective nickel-rich variant. These layered nickel-rich cobalt-free cathodes possess similar crystal structure and properties to conventional cobalt-containing cathodes like NCMs and NCAs, while demonstrating comparable or even superior electrochemical performance in some cases. This presentation will outline our research efforts in the development of these novel cathode formulations, including investigations into compositional landscapes, advanced characterizations, and evaluations of electrochemical performance.
Fluorinated Catholyte to Boost Lithium Primary Battery EnergyDr. Haining Gao for Dr. Betar Gallant, Massachusetts Institute of Technology
Lithium primary batteries, with energy densities up to 800 Wh/kg in packaged cell, are critical for stand-alone long-duration applications where recharging is impractical, such as implantable medical devices, unmanned autonomous vehicles, and remote monitoring. Li−carbon monofluoride (Li−CFx) battery, with a theoretical energy density of 2180 Wh/kgCFx+Li, is the current energy-leading system. However, to meet the demand for longer battery life and/or smaller battery size and weight, battery chemistries that can surpass the energy density of Li–CFx cell are greatly in need. Our research group has developed three generations of Li primary battery catholytes based on liquid fluorinated reactants (LFRs), which exhibit high specific energies (up to 1845 Wh/kgLFR+Li) by utilizing fluoride bond reduction. In addition, the LFRs are also compatible with CFx solid cathodes, allowing for the design of a solid-liquid hybrid battery system that substantially increases the energy of Li−CFx cell, with a projected boost of more than 50%. Herein, we will introduce the molecular structural design evolution of the three generations of LFRs. The electrochemical performances of these reactants and the characterizations of their discharge products using SEM, XRD, XPS, and UV-vis spectroscopy will be discussed. We will also examine and compare projected cell-level metrics. Overall, this study provides new insights into redox mechanisms of fluoride bonds, showing potential to underpin future conversion battery chemistries to significantly improve cell-level energy metrics.

Emerging Technology for Producing High Energy Density Cathode Active Materials, Dr. Ozge Kahvecioglu, Argonne National Laboratory

There is an incentive to implement emerging synthesis technologies that can lower manufacturing costs and the negative environmental impacts of lithium-ion battery. This is primarily due to the rapid changes in cathode material chemistries in recent years. Co-precipitation, followed by high-temperature calcination, is the current method for producing high-quality cathode powders. Aqueous co-precipitation processes are known to deliver the best cation mixing, and the most common system used by the battery industry is the continuous stirred tank reactor (CSTR). CSTRs have some drawbacks, such as undergoing very long stabilization times due to low mass and heat transfer rates. This presentation will focus on a new emerging synthesis technology, namely Taylor Vortex Reactor (TVR), for synthesizing cathode precursors, which overcomes several drawbacks we see in CSTRs techniques. As a case study, this talk will discuss high-energy-density cathode materials and their synthesis-performance relationships.

Chemistry-Agnostic Microstructure Design and Manufacturing of Cathode Materials, Dr. Feng Lin, Virginia Tech
Advances in Battery Technologies for Implantable Medical Devices, Mr. Robert Rubino, Integer Holdings Corporation
Batteries for active implants must have maximum reliability and predictability over a lifetime than could be 15 years or longer. Over the last 50 years, the industry has seen incredible advances in technology which have led to smaller devices that last longer and support improved device functionality such as sensing and communication. That evolution is expected to continue with further reduction of battery size resulting in even smaller devices, less invasive implant procedures and proliferation of active implants in the digital health ecosystem and as treatments for additional disease states.
Testing the Limits of Cell Voltage and Electrode Loading with LiNi0.5Mn1.5O4Dr. Marshall Schroeder, Army Research Laboratory

Transitioning toward more sustainable materials and manufacturing methods will be critical to continue supporting the rapidly expanding market for lithium-ion batteries. Meanwhile, energy storage applications are demanding higher power and energy densities than ever before. Due to its high operating voltage and cobalt-free chemistry, the spinel-type LiNi0.5Mn1.5O4 (LNMO) cathode material is one of the candidates capable of addressing this combination of challenges; however, severe capacity degradation and poor interphase stability have thus far impeded the practical application of LNMO. This talk will cover recent progress toward addressing these challenges by leveraging a dry electrode coating process and advanced electrolytes developed in collaboration with Professor Shirley Meng’s research group.

Are Solid State Batteries Ready for Mass-Adoption, Mr. Adrian Tylim, Blue Solutions
Solid-state batteries (SSBs) are considered the future of battery technology, offering improved safety, higher energy density, and greater durability compared to conventional lithium-ion batteries. Despite this potential, SSBs have often been perceived as a technology that is constantly ten years away from widespread adoption. However, it is essential to understand the current status of SSBs, including their achievements and the challenges that need to be addressed for their wide-scale implementation. In this discussion, we will explore the history of a company that has been successfully deploying SSBs for over a decade and delve into their near-future prospects.
Synthesis and Scaleup of High-Energy Single Crystal Ni-rich Cathodes for Advanced Li-ion Batteries, Dr. Jie Xiao, Pacific Northwest National Laboratory
High energy Ni-rich cathode will play a key role in advanced Li-ion batteries, but it suffers from moisture sensitivity, side reactions and gas generation. Single crystalline Ni-rich cathode has a great potential to address the challenges present in its polycrystalline counterpart by reducing phase boundaries and materials surfaces. However, synthesis of high-performance single crystalline Ni-rich cathode is very challenging, not mentioning a fundamental linkage between over potential, microstructure and electrochemical behaviors in single crystalline Ni-rich cathodes. This talk will explore cost-effective synthesis approaches for industry manufacturing and propose validation strategies for scaled Ni-rich single crystals.
