Solid-state lithium metal batteries offer superior energy density, longer lifespan, and enhanced safety compared to traditional liquid-electrolyte batteries. Their development has the potential to revolutionize battery technology, including the creation of electric vehicles with extended ranges and smaller more efficient portable devices. The employment of metallic lithium as the negative electrode allows the use of Li-free positive electrode materials, expanding the range of cathode choices and increasing the diversity of solid-state battery design options. In this review, we present recent developments in the configuration of solid-state lithium batteries with conversion-type cathodes, which cannot be paired with conventional graphite or advanced silicon anodes due to the lack of active lithium. Recent advancements in electrode and cell configuration have resulted in significant improvements in solid-state batteries with chalcogen, chalcogenide, and halide cathodes, including improved energy density, better rate capability, longer cycle life, and other notable benefits. To fully leverage the benefits of lithium metal anodes in solid-state batteries, high-capacity conversion-type cathodes are necessary. While challenges remain in optimizing the interface between solid-state electrolytes and conversion-type cathodes, this area of research presents significant opportunities for the development of improved battery systems and will require continued efforts to overcome these challenges.

A new chapter was opened when President Mung Chiang of Purdue University and President Chi-Hung Lin of National Yang Ming Chiao Tung University (NYCU) delegations signed two documents, in front of many witnesses including 10 members of the NYCU delegation. This monumental event occurred on the 27th of April, 2023, following an official visit by the Indiana Governor Eric Holcomb and his entourage, included the President and faculty members of Purdue University, eight month ago in September 2022. One of the documents is an executable Agreement for Student Exchange and the other is a Memorandum of Understanding for the Online Course Program with particular emphasis on semiconductors.
Two Presidents cordially exchanged ideas on many topics, but the semiconductor education and research are the main foci of the visit for which the NYCY delegates have had detailed discussion with Dean Arvind Raman of College of Engineering, Chief Semiconductor Officer Mark Lundstrom, and many faculty members from the Electrical and Computer Engineering Department.
A workshop was organized with state-of-the-art research presented by members of both Universities. No shortage of in-depth discussion on fascinating topics of the frontier advancement of semiconductor technology.
The visit to Purdue boilermaker would not be complete without a group photo in front of the Purdue University Arch in this rainy but happy day. Grateful to Purdue faculty and staff who have made the NYCU delegation visit a warmly received, carefully organized with productive ending.
