Meaning and Usage

"Pure cathode" refers to a type of cathode that is highly refined or composed entirely of a single element or compound, free from impurities. In the context of electronics and electrochemistry, a cathode is the electrode at which reduction reactions occur. The term "pure" indicates that no other materials or contaminants are present.

This phrase is primarily used in scientific and technical contexts, particularly within the fields of chemistry and electronics. It is more frequently encountered in written contexts, such as research papers, technical documentation, and industry talks, rather than in casual oral speech.

Example Sentences

1. The experiment required that we use a pure cathode to achieve accurate results.
   Эксперимент требовал, чтобы мы использовали чистый катод для достижения точных результатов.

2. Engineers often rely on pure cathodes to improve the efficiency of batteries.
   Инженеры часто полагаются на чистые катоды для повышения эффективности батарей.

3. The development of a pure cathode material promises significant advancements in fuel cell technologies.
   Разработка материала чистого катода обещает значительные достижения в технологиях топливных элементов.

Etymology

The term "cathode" comes from the Greek word "kathodos," which means "way down." It was coined in the early 19th century by scientists working with electrical currents, referring to the pathway that electrons travel in a circuit. The term "pure" comes from the Latin "purus," meaning "clean" or "unmixed."
