What Determines Solid Electrolyte Stability in Battery Systems
A solid electrolyte can show promising conductivity in a laboratory measurement and still perform poorly inside a battery. The difficulty often lies where it meets the electrodes: incomplete contact, chemical reactions or changes during cycling can introduce resistance that is not apparent from the material’s conductivity alone. Replacing a liquid electrolyte therefore requires more than…
How Do Temperature and Humidity Affect Biodegradable Materials
Biodegradable materials can behave differently in a warehouse, a delivery vehicle and the environment where they are eventually discarded. A film that remains usable during dry indoor storage may become softer after exposure to humidity, while a molded item may distort if its temperature rises beyond the range it was designed to withstand. These changes…
How Can Nanocoating Thickness and Adhesion Be Balanced
Nanocoatings can make a surface easier to clean, reduce water wetting, slow corrosion, or improve resistance to contact and abrasion. These functions do not all require the same coating structure. A water-repellent treatment may work through a very thin modification of surface chemistry, whereas a corrosion barrier needs coverage that limits the movement of water…
