Aim

The aim of the course is to give the students a basic understanding of lithium-ion batteries. Further the aim is to give the students practical skills in experimental characterization and design of a lithium-ion battery cell. Finally an important goal is to give the students a background in the assembly of cells to a battery as well as important aspects of its control and safety aspects in use.

Learning outcomes (after completion of the course the student should be able to)

  • Describe the parts in  Li-Ion Battery, materials and functionalities
  • Make calculations of capacity and energy efficiency of a LiB.
  • Use key equations for the physical modelling of a LiB
  • Perform EIS sweeps and capacity determinations
  • Make EECM (Equivalent electrical circuit models) of LiB EIS sweeps, with various complexities such as ZARC, and E-R-RC*n links
  • Interpret EECM of lower complexity into physical foundations in LiB
  • Describe a BMS and present its needed functionalities
  • Present important safety aspects of a LiB
  • Build a coin-cell provided that the needed equipment is at hand under guidance
  • Analyze a battery model using Comsol
  • Set up a test description for performing an ageing test of a LiB
  • Describe key ageing factors in LiB and be able to perform basic approximate ageing calculations
  • Give examples how batteries can be design to lower negative environmental impact.
  • Describe how battery systems can be designed for different applications
  • Perform thermal calculations on a LiB cell and system
  • Perform energy and power calculations on supercapacitors as well as describe to key parts of a supercapacitor

Content

There are three main parts of the course
  1. Electrochemical background for a lithium-ion battery functionality
  2. Model building for the voltage-current behavior of the battery (EECM)
  3. Composition of battery systems and important battery usage aspects
A project work with comprising practical and theoretical aspects is an important part of the course. Here, the course participants use COMSOL to make simulations on a battery cell, use knowledges from tutorials, lectures and literature to make theoretical calculations as well as results from measurements on an own-built coin cell.

Organisation

The course consists of 18 lectures (2*45 min), 8 tutorials (2*45 min), two practical laboratory exercises (2*4h) as well as 2 supervised computer exercises. In addition, there is a project work on 40 hours, that links the laboratory exercises with the lectures, tutorials and literature.
