Module code: ENGM288

Module Overview

Batteries, fuel cells, and supercapacitor are important electrochemical devices used as the power sources for a range of applications such as electric cars, power backup, portable electronic devices (e.g. laptops, e-pads, and mobile phones), etc. Many major cities around the world has set to ban the use of diesel and petrol cars in close future to reduce the illegal levels of air pollutions. Along this, the low efficiency associated with the current energy conversion techniques based on fossil fuels (e.g. combustion engines and gas turbines) has caused a great interests in using the alternative power sources. In this module, the students will learn the principles of modern electrochemical energy technologies and their applications in portable electronics, vehicle propulsion, and grid storage. Starting from the thermodynamic principles of electrochemical reactions and energy conversion, a knowledge in depth of selection, design, and applications of batteries, fuel cells, and supercapacitors will be covered in this module.

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

  1. Introduce thermodynamic principles and technical aspects of the major electrochemical energy storage and power sources.

  2. Represent different class of the electrochemical systems such as batteries, fuel cells, and supercapacitors by providing the relevant characteristics curves and quantitative analysis methods for estimating the systems efficiencies and performances through examples, problems, and exercises especially for emerging technologies such as electric vehicles and hybrid systems. The module will be delivered through lectures and in-class problem solving, as well as group discussions within the class.

The learning and teaching methods include:

  • 3 hours lecture per week x 11 weeks

  • 2 hours revision lectures

Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
