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.

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

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

Suresh 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

Alan 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.
