Researchers from various institutes across Korea have found a way to nearly double the life of the lithium-ion battery. In an ever-pressing race to create a more efficient and longer-lasting battery for electronics, researchers across the globe are looking toward alternative materials to make the li-ion battery stronger. A team of researchers associated with Samsung’s Advanced Institute of Technology, including ECS member Jang Wook Choi, have combined silicon and graphene to yield an amazing increase in lithium-ion battery efficiency.

ECS Executive Director recently sat down with co-author of the seminal Alkaline Storage Batteries and globally respected battery and biomedical researcher, Alvin J. Salkind, to take a look back on his tremendously influential career in the sciences. We are sad to say that Dr. Salkind has passed away since the recording of this interview. Take a look at some of the remarkable ways he impacted ECS. Listen to the podcast below and download this episode and others for free throught…

While working on a unique lithium-germanide battery, Pacific Northwest National Laboratory (PNNL) researchers knew something was happening inside the battery to dramatically increase its energy storage capacity, but they couldn’t see it. With no way to analyze the reaction occurring, the researchers could not understand the process. In order to solve the problem, the researchers developed a novel nuclear magnetic resonance (NMR) technique to allow insight and understanding of the electrochemical reactions taking place in the battery. Essentially, they have…

ECS treasurer E.J. Taylor (Founder & CTO of Faraday Technology), recently forwarded us a story from The Economist featuring ECS members and their contributions to research and development on the ever-improving lithium-ion battery. Since the battery’s commercialization by Sony in the early 1990s, the lithium-ion battery has improved to produce better laptops, smartphones, and even power electric cars. Vincent Battaglia, ECS member and head of the Electrochemical Technologies Group at Lawrence Berkeley National Laboratory, states that the lithium-ion battery “is…

Stanford University researchers have developed a new “designer carbon” that can be fine-tuned for a variety of applications, including energy storage and water filters. The newly developed carbon material has shown that it can significantly improve the power delivery rate of supercapacitors and boost the performance of energy storage technologies. “We have developed a ‘designer carbon’ that is both versatile and controllable,” said Zhenan Bao, past member of ECS and the senior author of the study. “Our study shows that…

Engineers from the University of Illinois at Urbana-Champaign’s College of Engineering have developed a high-performance 3D microbattery applicable for large-scale on-chip integration with microelectronic devices. “This 3D microbattery has exceptional performance and scalability, and we think it will be of importance for many applications,” said Paul Braun, professor of materials science and engineering at Illinois. “Micro-scale devices typically utilize power supplied off-chip because of difficulties in miniaturizing energy storage technologies. A miniaturized high-energy and high-power on-chip battery would be highly…
