About The Course:

This exploration delves into the electrification of the world by bridging chemistry and electricity for the purposes of energy conversion and storage. This course goes beyond mere understanding; it aims to impart a mastery of the principles that power our world. Our journey commences with an introduction to electrochemical cells, exploring the origin of potential and its capacity to drive current through a circuit. We will explore a variety of battery materials and discuss the mechanisms of energy storage within them, employing various non-destructive electrochemical techniques such as Cyclic Voltammetry (CV), Chronoamperometry (CA), Chronopotentiometry (CP), Differential Pulse Voltammetry (DPV), Galvanostatic Charge Discharge (GCD), Electrochemical Impedance Spectroscopy (EIS), and Galvanostatic Intermittent Titration Technique (GITT). For instance, I will elucidate the charging and discharging processes of a battery using analogies from everyday life.  In the second part of the course, how the battery technology is applied to EV will be discussed.  In this part, cell manufacturing process, cell modelling approaches, cell diagnostics, BMS, and battery recycling would be discussed. 

 

Market demands on this course: 

Battery demand for vehicles is steadily growing due to the upcoming battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs).  Currently, global sales of  BEV and PHEV cars are outperforming sales of HEVs(hybrid electric vehicles).  To meet the demand in the area of batteries, the requirement for critical materials for battery use is on a steady rise.  For example, in 2022, demand for Li exceeded the supply.  According to a report from the International Energy Agency, in 2022 alone, 60% of lithium, 30% of cobalt, and 10% of nickel out of the total production went only to EV batteries.  Therefore, it is important to develop advanced battery technologies to reduce the dependence on these critical materials to improve resilience and energy security. 

 

Why should anyone take this course?

This course gives a comprehensive view of materials, characterisation, and how it is applied to battery and battery integration with vehicles.  This would be useful for engineers who are working on the battery characterisation and maintenance side of the auto industry and grid energy storage sector.  Besides, it would help researchers to understand the underlying principle and chemistry of battery materials enabling them to venture to new and advanced battery materials development.

Module 1 : Battery Cell Materials

Module Description :

This Module covers the basics of electrochemistry and how to use it to understand the batteries.  Some analogy from commonly known examples will be used to introduce the advanced concepts like over potential and associated energy loss in batteries, which leads to thermal runaway situations.  Besides, the phenomenon responsible for energy storage, such as intercalation, alloying and conversion will be discussed with examples of anode and cathode materials used in the current state of the art Li-ion battery.  Besides electrical characterisation pertain to the anode, cathode and whole cell would be discussed in details, particularly non-destructive techniques to understand the state of health and state of charge of battery.
