8:45 High Performance Anodes with High Energy and Power Density
Yunfeng Lu, PhD, Professor, Chemical Engineering, University of California, Los Angeles
There are increasing demands for high-performance electrochemical-energy-storage devices, such as lithium ion batteries and fuel cells, for microelectronics, electrical vehicles, and other applications. Generally, such devices are operated through
charge separation in one electrode, during which electrons and ions are transported respectively through the external circuit and the electrolyte and recombined in the other electrode, accomplished through the redox reactions occurred in the electrodes.
Material design that lead to better charge separation, transport, and recombination, in this context, holds great promise towards better electrochemical-energy-storage devices. In this presentation, the design of electrode materials and electrolytes,
which lead to lithium-ion batteries with improved energy and power density will be discussed.
9:15 High Performance Li-Ion Cells with Silicon Nanowire Anode
Ionel 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 400 Wh/kg levels of energy density were achieved in lithium-ion
cells with a cycle life in the hundreds of cycles, enabling new devices and applications.

1:40 The Li Battery: From Its Origin to Enabling an Electric Economy
M. Stanley Whittingham, PhD, SUNY Distinguished Professor, Member, National Academy of Engineering, Director, NECCES EFRC at Binghamton, SUNY at Binghamton
50 years ago, a rechargeable battery achieving an energy density exceeding 100Wh/kg at room temperature was just a dream. Today, cells are exceeding 250Wh/kg. These cells have revolutionized electronic devices, have made EVs feasible, are dominating grid
storage, and enabling renewable energy. Yet the components of these intercalation-based cells have not changed significantly since the 1990s, and the cells still do not exceed 25% of theoretical capacity. Some of the challenges that need to be addressed
to doubling the energy density will be discussed.

Nongnuch
Artrith, PhD, Research Scientist, Chemical Engineering, Columbia University
The properties of batteries are often determined by complex phases and interfaces that are challenging to investigate with experiments or first-principles calculations. Simulations based on accurate and efficient machine-learning (ML) models trained on
first-principles data can provide insight into atomic-scale phenomena in such phases. The current state-of-the-art ML models will be demonstrated for nanostructured amorphous LiSi alloys and amorphous LiPON electrolytes.
4:30 Toward Low Cost and High Energy Batteries: K-Polyanion Cathodes
Haegyeom Kim, PhD, Staff
Scientist, Materials Sciences Division, Lawrence Berkeley National Laboratory
K-ion batteries have recently emerged as an alternative energy storage system because of their potential low cost. However, their energy density is limited when layered oxides, which are commercialized for Li-ion batteries, are used as cathodes because
of strong K-K interaction in the layered structure. This presentation will demonstrate how strong K-K interaction limits the energy density of the K-layered oxides and why K-polyanion compounds have higher energy density than the K-layered oxides.

Gerbrand
Ceder, PhD, Daniel M. Tellep Distinguished Professor of Engineering, University of California, Berkeley; Senior Faculty Scientist, Lawrence Berkeley National Lab
Recently discovered disordered rocksalt (DRX) compounds are dense cathodes with high energy density and present a cobalt and nickel-free alternative to the layered NMC-style cathode materials used in much of Li-ion technology. In addition, these materials
can be fluorinated through simple solid-state reactions for enhanced safety, cyclability, and stability at high potential. This presentation will show performance and issues with this exciting new class of compounds.
9:00 FEATURED PRESENTATION: Vanadium Disulfide Flakes with Nanolayered Titanium Disulfide Coating as Cathode Materials in Lithium-Ion Batteries
Nikhil
Koratkar, PhD, Clark and Crossan Chair Professor, Mechanical Engineering and Materials Science and Engineering, Rensselaer Polytechnic Institute
Unlike the vast majority of transition metal dichalcogenides which are semiconductors, vanadium disulfide is metallic and conductive. This makes it particularly promising as an electrode material in lithium-ion batteries. However, vanadium disulfide
exhibits poor stability due to large Peierls distortion during cycling. Here we report that vanadium disulfide can be rendered stable in a lithium-ion battery by conformally coating it with a titanium disulfide nanolayer.

studies of batteries developed and being developed for these applications; and 4) how production of both the cell components and cells are being scaled up and the associated timescales.
11:15 Improvements to Disordered Rocksalt Li-Excess Cathode Materials
Dee Strand, PhD, CSO, Technology,
Wildcat Discovery Technologies
Disordered rocksalt Li-excess structures, such as Li3NbO4, have been demonstrated to achieve capacities of greater than 300 mAh/g reversible capacities at elevated temperatures. The high capacity is believed to be due to reversible redox chemistry
of the oxide anions. This new class of high-energy cathode materials provides an opportunity for a step change increase in cell-level energy density. In this presentation, we demonstrate material improvements which enable high specific capacity
and cycle life.
11:45 Cross Talk in Lithium Metal Batteries: Unraveling the Influence of the Transition Metal Cathode on the Deposition/Dissolution Behavior and Morphology of Lithium
Johannes Betz,
MSc, Research Associate, MEET Battery Research Center, University of Münster
Research for lithium metal batteries is often conducted in Cu || Li or symmetrical Li || Li cells. However, the influence of different cathode materials on the Li metal electrode is demonstrated to be caused by the cross-over of transition metals
dissolved in the electrolyte, especially visible for LNMO || Li cells. This revelation supports the need for thorough investigations of Li metal anodes in full cells with a transition metal cathode.
