Are nickel-chromium batteries and nickel-cadmium batteries the same kind of battery? 

Cadmium has the symbol Cd on the list of chemical elements, "It is an excellent metal that absorbs neutrons. It can be made into rods to slow the rate of nuclear interlocking reactions in the atomic reactor, and it is quite useful in zinc-cadmium batteries. Its sulfide color is bright, used to make cadmium yellow pigment. Chromium (Chromium), chemical symbol Cr, simple substance is steel gray metal. The element name comes from the Greek, the original meaning is "color", because chromium compounds have colors , Is the hardest metal, and basically does not need to be used for battery materials. So what is the matter with nickel-chromium batteries? In fact, this is easy to understand, mainly because these two words have the same pronunciation, and it is easy to use nickel-cadmium when searching and typing online The batteries are labeled as nickel-chromium batteries. Over time, many people who do not make batteries will regard nickel-chromium batteries as nickel-cadmium batteries, so there is a name for nickel-chromium batteries on the market.


But why don't the manufacturers of nickel-cadmium batteries give corresponding explanations? In fact, it's very simple. No matter if you are searching for nickel-chromium batteries or nickel-cadmium batteries, as long as you can find them, there is no need to entangle them, and the manufacturers feel that there is no need to spend time and energy to do these.


In this way, the battery industry defaults that nickel-chromium batteries are called nickel-cadmium batteries.

So everyone will think that the parameters of nickel-chromium batteries are no different from those of nickel-cadmium batteries, and the parameters of nickel-chromium batteries become the following default data:

Nominal battery voltage: 1.2V cylindrical steel shell battery;


Advantages: low cost, good overcharge resistance, good fast charging performance, long cycle life, wide temperature range, moderate self-discharge rate, and good safety performance;


Disadvantages: cadmium metal pollutes the environment, the battery capacity is small, and the life is short. Ni-cadmium batteries have a memory effect. Each charge must be discharged first, and then charged.

But in fact, chromium is not used as a battery. Where are the advantages, disadvantages and parameters of these nickel-chromium batteries!
