Tailoring the Mechanical and Electrochemical Properties of an Artificial Interphase for High-Performance Metallic Lithium Anode

Mei Cai, Director, Battery Cell Systems Research Lab, General Motors Global R&D Center

Lithium metal is regarded as the “Holy Grail” of anode materials due to its low electrochemical potential and high theoretical capacity. Unfortunately, its unstable solid electrolyte interphase leads to low Coulombic efficiency. In this talk, a hybrid nanoscale polymeric film with tunable composition and improved stiffness will be discussed for Li metal anode protection. The Li plating/stripping process can be regulated through the protective coating to suppress the dendrite growth. This work provides guidance on the rational design of electrode interfaces and opens new opportunities for the fabrication of next-generation energy storage systems.

Origin and Evolution of LiH, LiF, and LiOH in Solid-Electrolyte Interphase of Lithium Metal Anode

Enyuan Hu, PhD, Associate Chemist, Chemistry Division, Brookhaven National Laboratory

A comprehensive understanding of the solid-electrolyte interphase (SEI) composition is crucial to developing high-energy batteries based on lithium metal anodes. But SEI comes in trace amounts and is prone to radiation damage, making characterization very challenging. We have recently developed a new way to characterize the SEI using synchrotron scattering and obtained a series of new results. I will first discuss the identification and quantification of LiH and nanocrystalline LiF in SEI. Following that, I will discuss our recent understanding of the origin and dynamics of LiH, LiF, and LiOH in the SEI and how these processes relate to the electrochemical performance of lithium metal batteries.

High-Performance Li-Ion Cells with Silicon Nanowire Anode

Ionel C. Stefan, PhD, CTO, Amprius, Inc.

The silicon nanowire anode technology addresses silicon swelling by enabling silicon to expand and contract internally, in a very robust mechanical structure. As a result, over 1200 Wh/L and 450 Wh/kg levels of energy density were achieved in Lithium-ion cells with a cycle life in the hundreds of cycles and fast charging in under 10 minutes, enabling new devices and applications.


Kenan Sahin, PhD, President, CAMX Power

High Nickel low Cobalt cathode materials for LIBSs improve energy density, reduce costs but lead to issues such as low cycle-life inter/intragranular cracking, surface degradation, gas evolution, and electronic/ionic isolation. We have mitigated these issues with globally patented grain- boundary engineering that can make Nickel rich materials viable and preferable for commercial use. Results for NMC, NCA and NMCA species with 6% Cobalt will be presented together with precursor formulations.

Lithium-ion cells can have incredible cycle (>10,000) and calendar lives (>40 years). I will explain how such long-lived cells can be made. The common belief is that only 800 charge-discharge cycles is enough for EVs so why do we need such amazing cells? Ninety percent of all Li-ion cells produced in 2030 will be used in EVs, so vehicle to grid storage is absolutely required to incorporate more renewables on the grid to reduce dependency on fossil fuels. Such awesome Li-ion cells are needed so EV batteries can support a large fraction of their charge-discharge cycles while parked.

Advanced Cathode and Electrolytes Design for High-Energy Li/S Pouch Cells

Guiliang Xu, Assistant Chemist, Chemical Sciences & Engineering, Argonne National Laboratory

Lithium-sulfur batteries are promising candidates for energy storage applications because of their high theoretical energy density. However, the fast capacity fading caused by lithium polysulfide shuttling and sluggish electrochemical redox kinetics of sulfur cathode under lean electrolyte and thick cathode conditions dramatically hinder their commercialization. To address these issues, advanced cathode structure design, and electrolyte modulation have been conducted at Argonne National Laboratory to simultaneously eliminate the shuttle effect and lithium dendrite formation, leading to the significantly increased cell energy density and cycle life in the practical Li-S pouch cells.

The Secret Life of Ionic Phases in the Lithium Solid-Electrolyte Interphase

Betar M. Gallant, Assistant Professor, Mechanical Engineering, Massachusetts Institute of Technology

Our work is developing analytical techniques to gain quantitative insights into Li anode solid electrolyte interphase (SEI) properties and reveal phase-specific interplays between chemistry, structure and function. These techniques allow for powerful chemical resolution of SEI-forming processes including difficult-to-probe interfacial chemical dynamics. Collectively, these insights reveal how different SEI phases form and evolve, and help to distinguish phases that support improved ion transport and plating morphology towards higher coulombic efficiencies.

Shin-ichi Iida, Manager, Product Strategy Department, ULVAC-PHI, Inc.

All-Solid-State-Batteries (ASSBs) have attracted attention as the Next Generation Batteries. However, there are still many challenges facing the commercialization of ASSBs. One big challenge is the internal resistance, especially generated at Cathode - Electrolyte Interface. This internal resistance limits the charge/discharge cycling performances. This study focuses on the understanding of the source of the internal resistance, by performing a detailed characterization using surface analysis methods.
