AABC 2014. Tutorial D: Inactive Materials in Lithium-Ion Batteries


Tutorial D:

Inactive Materials in Lithium-Ion Batteries


Martin Winter
Presented by:
Martin Winter, Chair, Applied Material Science for Energy Conversion and Storage, MEET Battery Research Center, Institute of Physical Chemistry, University of Muenster


Prof. Winter's main research interests are in applied electrochemistry, materials electrochemistry and inorganic chemistry and technology. He is the past president of the International Battery Materials Association (IBA), Past Chair of the Division of Electrochemical Energy Storage and Conversion of International Society of Electrochemistry (ISE), and Technical  Editor of the Journal of The Electrochemical Society (ECS). Currently, he is the spokesperson of the LIB2015 Innovation Alliance of the BMBF (Germany Ministry of Education and Research) and a member of the German National Platform E-Mobility (NPE).


Today, it is widely accepted that materials research in the field of electrochemical energy storage has to follow a system approach as the interactions between active materials, the electrolyte, the separator, and the various inactive materials is of similar or even higher importance as the properties and performance parameters of the individual materials only. In this presentation, we will discuss the influence of inactive materials on the performance of lithium ion batteries.

  • Active and Inactive Materials
  • General Considerations on Selection of Cell Materials
  • Battery Parameters Determined by (Proper) Material Selection
  • Basic Anode and Cathode Properties
  • “Inactive” Materials:
    1. Electrolytes,
    2. Separators,
    3. Current Collectors,
    4. Conductive Electrode Additives,
    5. Binders
