Fluorinated Catholyte to Boost Lithium Primary Battery Energy, Dr. 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−CF_x) battery, with a theoretical energy density of 2180 Wh/kg_CFx+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–CF_x 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/kg_LFR+Li) by utilizing fluoride bond reduction. In addition, the LFRs are also compatible with CF_x solid cathodes, allowing for the design of a solid-liquid hybrid battery system that substantially increases the energy of Li−CF_x 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

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

 

 

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.

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.
