Nanostructured Cathodes

Chapter 2 Battery Cathodes

Anode – (negative electrode) This electrode donates electrons during cell discharge. Battery A device consisting of one or many electrochemical cells connected together, in which chemical energy is converted into power. These can be further categorized as primary (non-rechargeable) or secondary (rechargeable) systems. Capacity The amount of charge that a battery contains, often expressed as mAh...

Nanostructured sulfur cathodes.

Rechargeable Li/S batteries have attracted significant attention lately due to their high specific energy and low cost. They are promising candidates for applications, including portable electronics, electric vehicles and grid-level energy storage. However, poor cycle life and low power capability are major technical obstacles. Various nanostructured sulfur cathodes have been developed to addre...

Les Rotations Et Les Quaternions

La construction du corps non commutatif H de quaternions est une variante plus compliquée de la construction du corps commutatif C de nombres complexes. Donc on commence en rappelant la construction de C à partir de R. Les nombres complexes s’écrivent a+ bi avec a, b ∈ R. Donc C est un espace vectoriel sur R de dimension 2 avec base {1, i}. La loi d’addition de C est celle que C possède en tant...
