In recent years, the development of advanced batteries aimed at new materials and solid-state battery systems, and the mainstream electrode design was based on a simple planar electrode stacking structure. However, emerging applications require batteries with both high energy density and high power density, which is impossible to be realized in traditional battery designs. In general, high power battery design will lead to low energy density, and vice versa. Developing innovative battery architecture can be a feasible means to solve this issue. 3D batteries possess not only fast charge-discharge feature inherited from thin-film batteries but also improve their energy density by elongating electrode structure without increasing the transport distance of electrons and ions. Since the processing methods of 3D batteries are highly related to those of semiconductor devices, it would be streamlined to integrate 3D batteries with microelectromechanical systems or self-powered chips. This review article will introduce the mechanisms, structural designs, manufacturing processes, classic design examples, and future prospects of 3D batteries.
CHANGING LANDSCAPE: After 20 years in the making, the merged university has finally launched with nearly 20,000 students and 1,400 lecturers across 19 colleges
Lin Chi-hung (林奇宏) yesterday assumed office as the president of the newly formed National Yang Ming Chiao Tung University, promising to boost the school’s ranking and international participation on its inauguration.
Lin, who has a doctorate in biology from Yale University, took the post after receiving a certificate of appointment in a ceremony presided over by Minister of Education Pan Wen-chung (潘文忠), along with several incoming presidents of other universities.
Plaque-unveiling ceremonies for the university, a merger of National Yang-Ming University in Taipei and National Chiao Tung University in Hsinchu, were held in Taipei and Hsinchu respectively.

Describing the merger as a milestone in Taiwan’s higher education, Lin said he hopes that students and faculty of the two universities support the newly formed institution.
Lin said he plans to unveil a three-year blueprint within 100 days that envisions a consensus-based development project for the university over the next 10 years, focusing on improving the school’s ranking in different aspects and boosting cooperation with top peers worldwide, while enhancing student exchange programs.
After 20 years of effort, the Executive Yuan and the ministry in August last year approved the merger plan of the two top-ranking universities, which have 1,400 lecturers and nearly 20,000 students across nine campuses, totaling 19 hectares.
In the initial stage, the university would have 19 colleges, six newly established research centers and a hospital, and would operate 14 daily shuttle buses between Taipei and Hsinchu.
