Lithium Batteries for Medical Applications

Recent advances in lithium technology have increased the variety of commercially available batteries. The element lithium possesses fundamental properties that make it ideal for use as the anode in both primary and rechargeable batteries. Vendors have paired the popular lithium anode with a variety of cathode and electrolyte materials, resulting in the wide choice of different chemistries available today. This article discusses the types of primary lithium batteries commonly used for medical applications and introduces a new type based on recent innovations in materials and manufacturing processes. Information about the basic properties, advantages, and disadvantages are provided for each battery type.

Starting Point for Overcoming Barrier to Fusion Power

The accuracy of a new model for predicting the size of a key barrier to fusion power, which was developed by physicist Robert Goldston of the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL), has been confirmed. Goldston’s model predicts the width of what physicists call the “scrape-off layer” in tokamaks, the most widely used fusion facilities.

The Future of Iron-Air Batteries

A University of Southern California research team has developed a cheap, rechargeable battery that could be used to store energy at solar power plants for a rainy day. The air-breathing battery uses the chemical energy generated by the oxidation of iron plates that are exposed to the oxygen in the air — a process similar to rusting.

New Tech for Grid-Level Electrical Energy Storage

Electrical energy storage is the obstacle preventing more widespread use of renewable energy sources. Due to the unpredictable nature of wind and solar energy, the ability to store this energy when it is produced is essential for turning these resources into reliable sources of energy. The current U.S. energy grid system is used predominantly for distributing energy and allows little flexibility for storage of excess or a rapid dispersal on short notice. Drexel University researchers believe they have a solution.
