Andreas Hintennach, PhD, Professor, Research HV Battery Systems, Daimler AG

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 and 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.

9:55 Advanced High-Ni Cathode Materials for xEV Applications

Young-Min Choi, PhD, Senior Research Fellow & Vice President, Advanced Materials R&D, LG Chem

High-capacity nickel-based cathode materials have become the principal candidates for a lithium–ion energy storage system powering electrified transportation units. With the aim of achieving high capacity with satisfactory battery lifetime, stabilization of the nickel-based cathode has become a globally competitive topic. In this talk, we will discuss a range of the nickel-rich layered oxides, starting from commercially available and currently used materials to promising novel materials that may be commercialized in the future. Fundamental properties, opportunities, challenges, and latest progress of high-Ni cathode materials research will be discussed.

14:20 From Lithium Metal Powder to High Energy Batteries

Adam Best, PhD, Principal Research Scientist & Research Grp Leader, Metal Industries, CSIRO Manufacturing

In order to enable higher energy batteries lithium metal is a key requirement for the anode. At present, there are a number of challenges to produce Lithium metal sustainably whilst ensuring that Lithium metal foils used in devices do not turn dendritic on continuous cycling. This presentation will address both of these topics and describe innovations which are being developed at CSIRO Australia.

14:45 전고체 배터리용 황화물 유리 전해질과 유리 세라믹 전해질

Atsushi Sakuda, Assistant Professor, Applied Chemistry, Osaka Prefecture University

The most important component of all-solid-state batteries is a solid electrolyte. Some solid electrolytes have demonstrated lithium-ion conductivities of over 10-2 S cm-1, which is greater than in conventional liquid electrolytes. In addition to the conductivity, understanding the mechanical properties and chemical stability in humid conditions is important to battery manufacturing and for long-term reliability. Our recent research on those properties of sulfide glass and glass-ceramic electrolytes will be introduced.

15:50 롤-투-롤 프로세스를 이용하여 제조되는 대형 전고체 배터리의 진보

Doug Campbell, CEO, Solid Power

All-solid-state batteries (ASSB) have significant potential for providing greater energy and safety as compared to conventional lithium-ion batteries. However, one area of concern is manufacturability and associated costs for ASSBs. In 2019, Solid Power installed its first automated, roll-to-roll production line in order to achieve higher-quality ASSBs and at volume. Solid Power’s talk will provide an overview of Solid Power’s manufacturing approach, as well as preliminary performance data on ASSB cells produced using its small volume production line.

16:15 A Long-Cycling All-Solid-State Lithium Metal Battery with Sulfide Solid Electrolytes

Yong-Gun Lee, PhD, Samsung Advanced Institute of Technology (SAIT), Samsung Electronics

All-solid-state battery (ASSB) with a lithium metal anode is a strong candidate for surpassing conventional lithium-ion battery (LIB) capabilities. However, undesirable Li dendrite growth and low Coulombic efficiency impede their practical application. We report herein, an all-solid-state lithium metal battery with a sulfide electrolyte which exhibits high energy density and superior cycle life. An NMC cathode with high specific capacity (>210 mAh g-1) and high areal capacity (>6.8 mAh cm-2) was employed, and a newly designed anode comprising a silver-carbon (Ag-C) composite layer was used in the ASSB. Repeated Li metal plating and stripping between the Ag-C nanocomposite layer and the stainless steel (SUS) current collector during cell cycling was demonstrated. A prototype pouch cell (0.6 Ah) thus prepared exhibited high energy density (>900 Wh L-1), stable Coulombic efficiency over 99.8% and long cycle life (1000 times).

 

 

16:40 탄산염 기반 전해질에 의한 장기 충방전 사이클을 실현하는 리튬 금속 표면의 개발

Dee Strand, PhD, CSO, Wildcat Discovery Technologies

Significant progress towards the passivation of Li metal anodes must occur before any of the anode’s potential can fully be realized. To this end, Wildcat Discovery Technologies has developed both in situ and ex situ surface passivation methods for lithium metal to significantly boost the cycling performance of lithium metal batteries. We will show investigation of passivation materials in combination with a variety of electrolyte compositions.

Shuichi Ishimoto, PhD, Section Manager of Advanced Material Group, Basic Research Center, R&D Headquarters, Nippon Chemi-Con Corp.

In order to enhance the cycle durability of Li-ion batteries (LIBs) for xEVs, we have developed a novel conductive carbon material called NH Carbon. The NH Carbon has a unique coating ability on the active materials’ surface in both negative and positive electrodes. Therefore, the cycle life of LIBs with the NH Carbon can be improved drastically. In the presentation, we will introduce the feature, effectiveness, and mechanism of the NH Carbon.

9:30 고에너지 리튬이온 배터리용 고성능 바인더

Tatsuo Horiba, PhD, Professor, Department of Applied Chemistry, Tokyo University of Science

We have been demonstrating that water-soluble binders provide better electrode performance than PVdF, which is due to uniformly dispersed electrode materials, sufficient coverage of active material surface, etc. Therefore, we named such binders “functional binders.” We will present some results on functional binders for lithium-ion batteries, with their feature, performance and working mechanism, focused on sodium polyacrylate (PANa), polysaccharides, lithium poly-γ-glutamate (LiPGlu), and styrene-butadiene rubber (SBR)/sodium carboxymethylcellulose (CMC).

10:50 고농도 전해질 개발의 진전과 문제점

Atsuo Yamada, PhD, Professor, The University of Toyko

In the past few years, a major breakthrough in electrolyte materials was achieved by simply increasing the salt concentration in suitable salt/solvent combinations. This long-awaited, extremely simple, yet effective strategy can overcome most of the remaining hurdles limiting the present lithium-ion batteries without sacrificing manufacturing efficiency. I will try to provide timely information that will be valuable for designing more realistic batteries.

11:15 이온 액체를 이용하여 설계된 첨단 전해질을 이용한 시스템의 안전성 강화

Paul Homburger, Vice President, Business Development, NOHMS Technologies, Inc.

Safety is a key industry challenge, but the definition of “safe” is construed in many ways.  What is "safe" and attaining it are open questions. This talk explores failure mechanisms making cells unsafe.  With this insight, NOHMs’ safety-enhanced solutions using advanced ionic liquid-based electrolytes are introduced.  Test results illustrate strong safety in next-generation cells.  How these materials reduce overall battery systems cost while providing large safety margins will be better-understood.

NanoramicLaboratories11:40 Introduction to Neocarbonix: Binderless Electrodes for Lithium-ion Batteries

Nicolo Brambilla, CTO, Nanoramic Laboratories

Electrodes are limited in their electrochemical stability and electrical performance by polymer binders.  Nanoramic has developed an alternate solution - Neocarbonix - an electrode platform technology that effectively replaces polymer binders and primers.  Results have been demonstrated for both LIB cathodes and EDLC electrodes. Nanoramic's Neocarbonix electrodes have significantly lower ESR, better C-rate capabilities, longer lifetime at high temperature, and greater active material thickness for improved energy density, while also retaining or improving specific capacity.
