A Battery Experiment Design for Electrical Engineering Course Extension Education

The continuous intersection and integration of energy disciplines promote the innovation of electrical engineering subject construction and talent training. However, the rapid transition also brings challenges. Restricted to the traditional instructional concepts and limited funds, numerous specialized courses are not able to be updated in time, which leads to the monotonousness of students' knowledge system and lack of study interest. Besides, the continuous refinement of investment triggers the constantly expanding of subject content, and the interdisciplinary of the new content makes it difficult for students to digest. To cultivate students' interdisciplinary thinking and stimulate their interest in study, a battery experiment designed by both students and teachers is proposed and used in electrical engineering teaching. This paper presents the main steps of the experiment, including the assembly and testing of the lithium perchlorate battery with dual-graphite electrodes, which is of great safety, economy, and feasibility. The teaching strategy and improvement measurements are also introduced, and the assistance of the experiment to power system planning is well discussed. This experiment has been added as an extension part of Power System Planning, and its effectiveness in cultivating students' enthusiasm and effectiveness get proved.
