This summer, an instructional team of battery experts from industry and the University of Michigan will teach a short course in battery manufacturing. The course runs from June 19-22.

The program outline is listed below with a brief description of the topics and learning objectives that will be covered.  Course instructors are experts in the various aspects of battery manufacturing, with extensive real-world expertise. The classroom instruction will be complimented with hands-on instruction in the Battery Lab at the University of Michigan. The cost for this course is $1500. 

Battery manufacturing COURSE OUTLINE

The overall objective of the course is to give participants insight in the various aspects related to battery manufacturing. The course combines classroom instruction with hands on experience building batteries in the battery lab.

AUDIENCE

The course aims to fill a particular need: teach participants the key skills needed to scale up battery innovations. The target audience consists of engineers, chemists, and material scientists that work for companies developing batteries for a range of applications: automotive, consumer products, grid-scale storage, etc.  

Day 1:

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

Introduction to Battery Design and Safety

Instructor: Larry Beck, Energy Storage Consultant

  • 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 session (Dr. Greg Less):

Preparing battery slurry for anode and cathode

Day 2:

A deeper dive in to understanding anode and cathode slurry preparation and rheology testing. We will be measuring the quality of the slurry started on day 1, and demonstrate the battery coating process.

Mixing and Rheology

Instructor: Dr. Bernhard Stalder, Senior Technologist Battery Solutions, Bühler AG

  • Mixing and rheology testing of electrode slurries
  • Wet grinding of LIB precursors and active materials
  • Introduction to the various coating methods

Hands on session (Dr. Greg Less):

Coating & Calendaring

  • Measure slurry quality
  • Foil and slurry loading
  • Coating (reverse comma)
  • Analysis of coating quality
  • Calendaring

Day 3:

A more thorough explanation of battery electrochemistry, followed by exploring next generation battery chemistries, presented by University of Michigan faculty.

Battery Electrochemistry

Instructor: Prof. Bart Bartlett, University of Michigan   

  • 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 (Prof. Jeff Sakamoto)
  • Metal-air batteries (Prof. Neil Dasgupta)
  • Flow batteries (Prof. Levi Thompson)

Day 4:

On this 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 portion of the day, we will assemble our coated material in to cells, and prepare them for testing.

Overview of Battery Testing, 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 session:

Cell assembly & testing

  • Electrode punching
  • Z-fold stacking
  • Tab welding
  • Electrolyte fill
  • Sealing
