To prepare for research in battery technology after completing an undergraduate engineering course, chemical engineering is identified as the most relevant discipline due to its strong focus on chemistry, physics, and material science. While mechanical and electrical engineering also contribute valuable knowledge, particularly in thermodynamics and manufacturing processes, they are considered secondary to chemical engineering for this specific field. Additionally, pursuing a dual degree, such as mechanical and chemical engineering, may enhance preparedness for battery research. It is emphasized that beyond technical skills, securing funding for research is a significant challenge in advancing battery technology. Engaging with businesses in the battery sector and exploring specialized graduate programs are recommended for further development in this area.
