13:30 → 15:15 Basics of Battery Electrochemistry

The very first module of the course will introduce the definitions and expressions relevant to the technical electrochemistry. Then, the basics of battery electro-chemistry will be discussed including both the thermo-dynamics (electrode potential, cell voltage) and the kinetics (ohmic, charge transfer, and concentration overpotentials). Finally, the application of this basic knowledge to porous electrodes will be shown.

Speaker: Prof. Petr Novak (Paul Scherrer Institut)

08:30 → 10:15 Characterization of Cell Components

The goal of this lesson is to get insight into a battery during cycling using advanced characterization techniques and combining information from the bulk, the interface and the surface. We will thus review the characterization techniques existing through various examples looking at the cell components (electrodes, electrolytes, separators etc.).

Speaker: Dr Claire Villevieille (Paul Scherrer Institute)

Slides 03_Characterization_of_Components_Villevieille.pdf

10:45 → 12:30 Ageing and Safety of Cell

In this module we will study the different causes of aging of rechargeable batteries (SEI layer formation, electrode dissolution, etc.), and the influence of operational parameters (depth of discharge, temperature, current and current ripples) for the most important cell chemistries. The difference between the capacity fade due to calendar life vs. cycle life is addressed. Finally the contribution of each component to battery safety and the selection criteria for types of rechargeable batteries regarding the costs, safety and capacity fading is discussed in this lecture.

Speaker: Dr Donat Adams (Reliability Science and Technology - Empa)

Slides 04_Aging_and_Safety_Adams.pdf

13:30 → 15:15 Physicochemical Modeling and Simulation

Physicochemical models are being widely used to understand the properties of lithium-ion batteries, to support electrode and cell design, and to reduce development cost. This class includes a first overview of modeling approaches (Newman-type models, micro-structureresolved models, multi-scale models). Then governing processes and model equations, simulation software and implementation as well as challenge model parameterization will be discussed. The lecture closes with application examples: Lithium-ion battery lifetime prediction; Metal-air battery chemistry.

08:30 → 10:15 Thermal Modelling and Management

Thermal management is a mayor issue, especially for lithium-ion batteries. Too high as well as too low temperatures causes accelerated degradation. In addition the temperature distribution inside a lithium-ion cell and between different cells of a battery system should be as homogeneous as possible. To achieve this requirements an adequate thermal management is needed, which has to be integrated into the super ordinate system.

Speaker: Dr Gerhard Rizzo (Institute for the Development of Mechatronic Systems | University of Applied Sciences and Technology Buchs NTB)

Slides 07_Thermal_Mod_a_Management_Rizzo.pdf

10:45 → 12:30 Lithium Battery Design and Production

The implementation of electro-chemical energy storage is demanding as some of the used materials are quite reactive. This lecture gives an insight of principal lithium battery design and production processes. In a second part, a closer look at the development process, from design to production release, will be taken.

Thursday, 14 July

08:30 → 10:15 Battery System Components

For a complete battery system additional hardware is required. The battery management system (BMS) monitors the operating values (voltages, currents and temperatures) and protects the battery cells from being used outside their safe region. The hardware and software structure of such a BMS must meet certain requirements regarding low power consumption, safety critical behavior and accuracy. The current interrupting devices (CID) as well as fuses and current sensors should be carefully designed and their sizing depends on the application of the battery system.

Speaker: Prof. Vezzini Adrea (BFH-CSEM Energy Storage Research Center)

Slides 11_Battery_System_Components_Vezzini.pdf

10:45 → 12:30 BESS Technology for Public Transportation and Green Power Grid

This lesson begins with business cases for "new" applications. The technology of dimensioning and cooling lithium-ion batteries in electric buses, home energy storage, and sub-stations is discussed. A semi-empirical battery model will be introduced, followed by a discussion on the implications and limitations of this approach. Finally, a brief discussion on future electrochemical technologies will be held (time permitting).

Speaker: Dr Timothy Patey (ABB Corporate Research)
