Carbon Graphite in Batteries In this blog, we’d like to explain the advantages of carbon graphite as a negative electrode material in batteries. But first, a quick review for those new to this blog: What is graphite? What is Graphite? Some elements can exist in different forms. These forms are called allotropes. Sulfur, for instance, has many allotropes, more than any other element. Graphite is an allotrope of carbon, and, in fact, is the most stable form of carbon. “Wait!” we hear you saying. “Aren’t diamonds a form of carbon, and how could you get more stable than a diamond?”...

Synthetic Graphite Supply Chain Update

Synthetic Graphite Supply Chain Since early 2020, Semco has been detailing in these blogs how pandemic-related supply chain issues have affected the synthetic graphite industry. Now that many of the supply chain issues we heard about so much in 2020 and 2021 have subsided, we wanted to check in on how this issue is affecting the availability of, and demand for, synthetic graphite. Lithium-ion Battery Anodes and Graphite Electrode Machining Apart from lithium, there is one material that is currently a fundamental part of all lithium-ion batteries, regardless of cathode chemistry: graphite. Graphite is a strangely unnoticed piece of the...
