Learn the Key Skills Needed to Scale Up Battery Innovations

 
This four-day course covers the fundamentals of battery cell manufacturing, giving you an understanding of energy storage technologies and teaching you the skills to scale up battery innovations at your organization. Through hands-on sessions in the University of Michigan Battery Lab and instruction from faculty and industry experts, you will gain exposure to the aspects of building a battery from start to finish.
 

Program Agenda

 
Day 1: Introduction to Battery Design and Safety

The course begins with a description of the basic components of batteries and their key parameters that determine battery performance and safety. The hands-on portion will demonstrate the first step in the battery manufacturing process, battery slurry preparation.

Instructor: Dr. Larry Beck

  • What are the key components of a battery?
  • What is a good electrode design?
  • Overview of active materials
  • Overview of electrolyte systems
  • How do you safely handle batteries in a prototyping environment?
  • What are the variables that affect battery performance and safety?

Hands-on Battery Lab Session

Instructor: Dr. Greg Less

  • Preparing battery slurry for anode and cathode
Day 2: Mixing and Rheology

Next, we will take a deeper dive into understanding anode and cathode slurry preparation and rheology testing. We will measure the quality of the slurry started on day one and demonstrate the battery coating process.

Instructor: Dr. Bernhard Stalder

  • Mixing and rheology testing of electrode slurries
  • Wet grinding of lithium-ion battery (LIB) precursors and active materials
  • Introduction to the various coating methods

Hands-on Battery Lab Session

Instructor: Dr. Greg Less

  • Measure slurry quality
  • Foil and slurry loading
  • Coating (reverse comma)
  • Calendering
  • Analysis of coating quality
Day 3: Battery Electrochemistry

This day consists of an explanation of battery electrochemistry, followed by an exploration of next generation battery chemistries presented by University of Michigan faculty.

Battery Electrochemistry

Instructor: Prof. Bart Bartlett   

  • Battery components and electrochemical cells
  • Capacity (Faraday’s Law) and voltage (Nernst equation): Electrodes
  • Diffusion, Migration, and Transference Number: Electrolytes
  • Voltage drop and electrode geometry
  • (Fully) Interpreting Charge-discharge Curves
  • Characterization tools relevant to battery development

Next Generation Battery Chemistries

  • Solid state batteries (Instructor: Prof. Jeff Sakamoto)
  • Metal-air batteries (Instructor: Prof. Neil Dasgupta)
  • Flow batteries (Instructor: Prof. Levi Thompson)
Day 4: Battery Testing

On the final day, we will cover the equipment and the procedures used to test batteries. We will discuss how to analyze test results. For the hands-on session, we will assemble our coated material into cells and prepare them for testing.

Instructor: Dr. Tal Sholklapper

  • Review of major tester brands
  • Common test protocols
  • In-depth analysis of test results.
  • Cycling protocols, rate characterization, hybrid pulse power characterization, and impedance analysis

Hands-on Battery Lab Session

Instructor: Dr. Greg Less

  • Cell assembly and testing
  • Electrode punching
  • Z-fold stacking
  • Tab welding
  • Electrolyte fill
  • Sealing
  • Formation

U-M Battery Lab

Dedicated in Fall 2015, the Battery Fabrication and Characterization User Facility is a space developed in cooperation with the Michigan Economic Development Corporation and Ford Motor Company. This lab enables industry and university researcher collaboration on developing cheaper and longer lasting energy-storage devices in the heart of the U.S. auto industry.

 

Program Faculty

An instructional team composed of battery experts from industry and the University of Michigan will teach this course. The instructors are experts in the various aspects of battery manufacturing, with extensive real-world expertise.
