What are the different parts of a battery? A short summary:
--anode: the negative electrode during discharge. While charging,
this becomes positive. In AA and AAA batteries, this is usually the
protruding part on the top.
--cathode: the positive electrode during discharge. While charging,
this becomes negative. In AA and AAA batteries, this is usually the
flat part on the bottom.
--seal: a part of the battery cell that makes sure chemicals cannot
leave the battery. It also limits air intake. A good seal is
essential for a safe battery.
Technical battery terms explained
Whereas they're simple to use, the electrical processes are often a
little more complex. Let's take a look at the most common technical
battery terms used:
--capacity: the amount of energy that is stored inside a battery.
It is measured in mAh (milliamp hours).
-- voltage causes electric charges to move through the wire or
other conductors. It is measured in volt (V).
-- cycle: one sequence of charge and discharge, or: how many times
you can use and recharge a battery. Every rechargeable battery has
a set amount of cycles (i.e. cycle life) before it starts losing
capacity and efficiency.
Ni-Cd Battery Cell Performance:
1. Ni-Cd Cell Charge Curve At 0.1C For 16h At 55 Degree
