Electrochemistry Crash Course for Engineers

Description

This book is a concise introductory guide to understanding the foundations of electrochemistry. By using simplified classroom-tested methods developed while teaching the subject to engineering students, the author explains in simple language an otherwise complex subject that can be difficult to master for most. It provides readers with an understanding of important electrochemical processes and practical industrial applications, such as electrolysis processes, metal electrowinning, corrosion and analytical applications, and galvanic cells such as batteries, fuel cells, and supercapacitors. This powerful tutorial is a great resource for students, engineers, technicians, and other busy professionals who need to quickly acquire a solid understanding of the science of electrochemistry.
