Battery Chemistries for Automotive Applications

Recent Advancements in Battery Chemistries

June 24-25, 2019


The Advanced Automotive Battery Conference attracts international thought leaders and battery technologists to discuss key issues impacting the electrification of vehicles. As the electric vehicle market expands with increasingly strict regulatory deadlines, the need to improve batteries and enhance performance while lowering cost has never been stronger. AABC provides a scientific and interactive forum to explore these challenges. In this session, leading materials R&D professionals will review the prospects of advanced cathodes, anodes, and electrolytes to deliver better performance, life, and safety, at equal or lower cost than current chemistries, and to provide enhanced value for large lithium-ion batteries.

1:35 Joint Center for Energy Storage Research (JCESR): Overview and Focus

Srinivasan_VenkatVenkat Srinivasan, PhD, Deputy Director, Research & Development, JCESR

The Joint Center for Energy Storage Research, otherwise known as the Battery Hub, is a US Department of Energy Innovation Hub focused on developing the science behind next-generation batteries that can help usher in a more resilient electric grid and electrify transportation. While batteries today are becoming more cost effective for many applications, their widespread penetration requires further cost reduction and performance improvements. Revolutionary new materials are needed that can outperform the ones available today; however, many scientific challenges prevent these materials from being used in the real world. In this talk we will describe the science gaps JCESR is addressing, the goals, and the approach that is being taken, along with a few key highlights.

Li metal is a key electrode material for developing high energy batteries with a specific energy much higher than 300 Wh kg−1. Despite intensive efforts, significant challenges remain in direct utilization of Li metal anode in realistic high energy cells. This talk will summarize our current understanding of the scientific and technological challenges, discuss recent progress and propose potential directions based on a high-energy cell design, fabrication and testing. The fundamental relationship between the Li anode and other cell components, especially electrolytes, is explored at the cell level in order to inspire more new ideas to effectively address the grand challenges in high energy Li cells.

Novel and sustainable electroactive materials can help to decrease the ecological impact of novel battery concepts soon. While on the one hand, high energy density is required, the aspects of safety, lifetime get more important and often mean a challenge. All these requirements are met by very different approaches with different characteristics: all-solid-state cells, high-energy materials, lithium-sulfur and even different systems, e.g. Na- or Mg-Ion.

3:55 400Wh/Kg Is Here, a Practical Approach to Solid-State Lithium Metal Cells

Sisk_BrianBrian Sisk, PhD, Vice President, Cell Product Development, A123 Systems

Lithium-ion batteries have seen significant improvements in energy density in recent years, raising expectations for electric vehicle adoption. However, energy density approaches a threshold at which the pace of improvement is limited by safety requirements. Solid-state batteries solve this problem by eliminating flammable liquid electrolyte, safely allowing high-energy batteries. The coming solid-state battery revolution presents significant opportunities to automakers in terms of safety and potential cost savings – but will also require drastic system-level changes. In this presentation, I will demonstrate the great promise of solid-state batteries, identify opportunities for vehicle cost savings, and focus on system integration challenges.

Ceramic solid electrolytes, such as Li7La3Zr2O12 (LLZO), with garnet structure have been developed as promising solid electrolytes for use in all solid-state batteries. However, the performance of these types of materials is very sensitive to both composition and processing. In this work, we carefully explore the relationship between composition, processing, and performance using systematic experimental approaches.

Abraham_DanielDaniel P. Abraham, PhD, Senior Materials Scientist, Chemical Sciences and Engineering, Argonne National Laboratory

Rapid charging of lithium-ion batteries would enable wider adoption of electric vehicles but the high-current regimes affect electrochemical characteristics and longevity of the battery cells. Formation of Li metal deposits is a recognized hazard of high-rate charging. We will highlight the use of a microprobe reference electrode to monitor the onset of Li plating conditions in situ and discuss lithium concentration gradients that develop in the electrodes during fast charging.

Lithium-ion batteries are beginning to transform the transportation sector, but the scarcity and high cost of cobalt pose serious problems for their deployment for electric vehicles and grid storage. This presentation will focus on the design and development of high-nickel, low-cobalt cathodes for lithium-ion batteries. Full cell data with graphite anode for thousands of cycles and an in-depth characterization of the cycled electrodes after extensive cycling will be presented.

3:20 High Nickel NCA Cathode Materials with Grain Boundary Enhancement

Sahin_KenanKenan Sahin, PhD, President and Founder, CAMX Power LLC


Sriramulu_SureshSuresh Sriramulu, PhD, Head, Advanced Development, CAMX Power LLC

This talk will discuss the benefits of adding other elements (in addition to cobalt) to the grain boundaries using materials from the NCA family. Specifically, we will discuss scaling-up the synthesis of these materials, their implementation in multi-Ah cells, as well as the economics of synthesizing grain boundary enriched materials relative to conventional materials.

3:40 Why ALD Nanofilms on Cathode Materials Improve Li-ion Battery Performance

Weimer_AlanAlan Weimer, PhD, H.T. Sears Memorial Professor, Chemical and Biological Engineering, University of Colorado, Boulder

The true nature of low-cycle number ALD films on NMC materials is elucidated using focused surface characterization.  It is commonly assumed that several ALD cycles form a uniform film that optimally is thin enough to facilitate lithium diffusion while blocking side reactions of the electrolyte with the cathode material.   We show that ALD films are not uniform and grow preferentially on metal oxides, stabilizing them in the presence of electrolyte without blocking lithium intercalation pathways.
