How it's used

Technical terms like this are often borrowed directly from written Chinese in academic or professional settings. While the term is standard in physics and chemistry, native speakers might simply use the English word cathode in casual conversation to avoid ambiguity. Understanding the distinction between the cathode and anode during charging versus discharging is crucial for electronics.

Common mistake

Learners often confuse 陰極 with 負極, but they are not always the same thing. In a discharging battery, the cathode is the positive terminal, whereas in a charging battery, it becomes the negative terminal.
