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
2. Ni-Cd Cell Discharge Curve At 0.25C At 55 Degree
3. Ni-Cd Cell Charge Efficiency At Different Temperature
4. Ni-Cd Cell Capacity Change At Permanent Charge At 55 Degree (0.05C Floating)
5. Ni-Cd Cell Cycle Life Curve
Application of Ni-Cd Battery
The Ni-Cd Battery is a type of rechargeable battery utilizing nickel oxide hydroxide and metallic cadmium as electrodes.
Sealed NiCd cells were at once widely utilized in portable power tools, photography equipment, flashlights, emergency lighting, hobby R/C, and mobile electronic devices. The superior capacity of this Nickel-metal hydride batteries, and more recently their lower price, has largely supplanted their use. What's more, the environmental effects of the disposal of the toxic metal cadmium has contributed substantially to the reduction in their use. Within the European union , NiCd batteries may now only be supplied for replacement purposes or for certain types of new equipment such as medical devices.
