In the world of batteries, there are a lot to choose from. Understanding the different types of batteries is essential to choosing the right ones for your needs, and for proper disposal as well. In this quick guide, we will provide you with information on a unique type of battery, the NiCd. Let’s dive right in.
What Is a NiCd Battery?
NiCd stands for a chemical abbreviation. These types of batteries are made up of Nickle and Cadmium, which is why they are referred to as NiCd. They are a type of secondary battery meaning they can be recharged. Nickel-cadmium batteries only contain the chemicals of nickel and cadmium. These chemicals come in various forms and compositions. In general, the positive electrode will be made of Nickel hydroxide while the negative electrode is made up of Cadmium hydroxide. Often the electrode is potassium hydroxide.
How Are They Different From Other Types of Batteries?
These batteries are different in many important ways. One of the most significant differences is the way they use voltage. A typical alkaline or lead-acid battery will have a cell voltage of about 2V. This voltage will steadily drop off as it depletes. NiCd batteries are unique, though, because they can keep a steady voltage of 1.2 V in each cell. This voltage will stay steady right up until the battery is depleted. This creates a more powerful delivery during the application. This is what makes this type of battery appealing.
Another distinct characteristic is that NiCd batteries is that they have very low internal resistance, meaning that the batteries can discharge a lot of power very quickly. It also means that the batteries can receive a lot of power very quickly. This also keeps the temperature low, which helps create a quick charge or discharge.
How To Discharge NiCd Batteries
NiCd batteries are perfectly safe to use as directed. However, it is very important that this type of battery is disposed of properly. Cadmium is a very toxic heavy metal. This type of battery should never be burned, and they should never be put into the regular trash. You should never attempt to break these types of batteries either.
To properly dispose of NiCd batteries should be disposed of according to the battery disposal rules and regulations for the area in which you live. Each town or city will have regulations for battery disposal.
