Battery Electrochemistry, Design and Manufacturing (for new MSc Sustainable Automotive Electrification)

Introduction

This is a Li-ion battery cell focused module for MSc in Sustainable Automotive Electrification (new course). This module consists of face-to-face teaching, hands-on lab sessions, tutorials, online learning, literature review assignment, take home examination assignment and post module assignment, for a total of 150 hours.

This module focuses on electrochemical energy storage principles, energy storage materials and chemical engineering processes of lithium-ion batteries, which is the major energy storage solution for automotive electrification.

The module will provide students with the scientific knowledge inside batteries to understand the fundamental mechanisms for battery operation, design and manufacturing. It will unlock the mysteries of battery cells rather than treating them as black boxes.

The module covers batteries up to the cell level to avoid any overlapping with another energy storage module which covers battery systems within the same MSc course.

Based on the state-of-the-art energy storage research facilities at WMG, four hands-on lab practicals are included in this module, giving students the first ever experiences of battery cell manufacturing and characterization.

Objectives

Upon successful completion participants will be able to:

  • Demonstrate conceptual analysis of electrochemical working principles of Li-ion batteries
  • Evaluate different energy storage materials for battery cell design and manufacturing
  • Comprehensively interpret battery cell degradation mechanisms and recycling processes
  • Practically assemble Li-ion battery cells and interpret the manufacturing processes
  • Independently evaluate battery cell testing results

Syllabus

  1. Battery fundamentals: key terminologies, lithium-ion battery components, functions, and operation principles.
  2. Electrochemical principles of energy storage in batteries: thermodynamics, kinetics and mass transport.
  3. Energy storage materials: chemistry of cathode and anode active materials.
  4. Manufacturing processes: synthesis method of energy storage materials; fabrication method of battery cells; recycling processes of lithium-ion battery valuable materials
  5. Degradation mechanisms of Lithium-ion batteries
  6. Four hands-on lab session: electron microscopy (characterization of energy storage materials); mixing and coating (battery electrode manufacturing); battery cell fabrication; battery forensics.
