9:05 Flammable, Toxic and Not Performant Enough: Is There a Chance to Get Rid of Liquid Organic Electrolytes
Martin Winter, Ph.D., Chair, Applied Material Science for Energy Conversion and Storage, MEET Battery, Research Center, Institute of Physical Chemistry, University of Muenster
It is common wisdom, that materials science in the field of electrochemical storage has to follow a system approach as the interactions between active materials, the electrolyte, the separator and various inactive materials (binder, current collector, conductive fillers, cell housing, etc.), are of similar or even higher importance as the properties and performance parameters of the individual materials only. For lithium metal and lithium ion batteries (LIBs), it is widely accepted, that the electrolyte interacts and reacts with the electrodes, influencing not only power density and life, but also safety. Here we reflect the present situation with organic LIB electrolytes with particular emphasis on safety and toxicity and will address the potential of future non-liquid (i.e., gel, hybrid and solid) electrolytes in view of realization novel cell chemistries, particularly lithium metal anode chemistries.
9:25Electrolyte with Improved Performance at Both Low and High Temperatures
Dee Strand, Ph.D., CSO, Wildcat Discovery Technologies
Automotive applications require batteries with adequate power down to -30°C to start the vehicle. In general, the power capability of the batteries suffers at low temperature due to increases in electrolyte viscosity, as well as poor ionic conductivity in the electrolyte and anode SEI layer. This presentation highlights development of electrolyte formulations with wide operating ranges on both graphite and lithium titanate anodes.
9:45 Stabilizing Water in Batteries
Kang Xu, Ph.D., Senior Research Chemist & Project Lead, US Army Research Lab
Water is the universal solvent in the universe, whose highly polar nature, unique structure and networking properties render its strong solvation power toward almost any inorganic salts. However, its narrow electrochemical stability window (1.23V) restricts its application in electrochemical devices whose electrodes operate at extreme potentials. In this talk, different approaches of stabilizing water electrochemically will be explored.

2:40 Towards All-Solid-State Batteries: A Delicate Balance between Materials and Processing
Olivier Guillon, Ph.D., Professor, Institut für Energie und Klimaforschung
All-solid-state Li- and Na-ion batteries promise to alleviate many issues related to the use of organic liquid electrolytes in conventional batteries and have the potential for improved safety and large increase in energy/power density. To achieve the latter, the combination of ceramic ion conductors with metal on the anode side and mixed cathodes, preferably with high voltage active materials, is necessary.

The pursuit of high energy density is at the heart of smartphones, wearable gadgets, wi-fi communication and electric vehicles. Lithium, which is the lightest and most electronegative metal in the periodic table, is a natural choice as anode. SolidEnergy’s mission is to power people’s lives, whether they are communicating with loved ones on a phone, driving with family in an electric car, or accessing the internet for the first time in a remote village in Africa.
3:20 Dendrite-Free Rechargeable Zinc-Based Batteries: Solving a Chronic Impediment through Architectural Design
Debra Rolison, Ph.D., Head, Advanced Electrochemical Materials, Surface Chemistry Branch, U.S. Naval Research Laboratory
The key to realizing rechargeable zinc alkaline batteries lies in controlling the behavior of the zinc anode during cycling.
