Electrochemical Energy Storage

Indian Institute of Technology, Kharagpur and NPTEL via Swayam


This course illustrates the diversity of applications for secondary batteries and the main characteristics required of them in terms of storage. The introductory module introduces the concept of energy storage and also briefly describes about energy conversion. A module is also devoted to present useful definitions and measuring methods used in electrochemical storage. Subsequent modules are devoted to teach students the details of Li ion batteries, sodium ion batteries, supercapacitors, lithium – air, and lithium - sulphur batteries. Separate modules are also devoted to describe lithium reserves, extraction and recycling of Li ion batteries. Finally, other types of batteries including redox – flow batteries are described in a separate module. The course is divided into twelve modules each contains five half an hour lectures. Each module lectures is self contained to encourage student understanding and reinforce key concepts. Carefully designed problem set will help students to grasp the underlying concepts taught in the course.INTENDED AUDIENCE : 3rd or Final year UG and 1st Semester PG/Ph.D students studying Matallurgical and Materials Engineering/Materials Science/Ceramic Technology/Electrical Engineering/Energy Science/Nanotechnology (as one of the open elective courses)PRE-REQUISITES : High school knowledge in Chemistry, Physics and Mathematics are required. Knowledge on undergraduate level electrochemistry is a plus.INDUSTRY SUPPORT : Tata Steel R&D,Tata Motors,Amara Raja Batteries Limited,Various CSIR Labs
