Li Ion Battery vs Nicad- Introduction, Charging and Storage

Li Ion Battery vs Nicad- Introduction, Charging and Storage

Page view

In recent years, with the continuous development and progress of lithium battery technology, the manufacturing process of lithium-ion battery is becoming more and more mature, and the utilization rate of lithium battery is also increasing. Why are lithium batteries so popular  This is determined by its superior performance and strong practicability. This article will briefly introduce lithium batteries and traditional NiCad batteries, and provide more practical information for lithium battery buyers by comparing them.

Are li ion battery and NiCad batteries interchangeable

The answer to this question is affirmative. All batteries are used to supply power to electrical equipment. As long as you select the same battery specification and model as the battery to be replaced, it can be replaced (except for electrical appliances with special requirements for operating voltage and current). As long as it is a battery appliance, it should be compatible with a variety of batteries. For these batteries, the capacity and discharge rate determine the service time, and the charging method and efficiency also affect the flexibility of the battery. In fact, at present, lithium-ion battery is completely replacing NiCad battery, because lithium-ion battery has better performance. Next, the article will list the advantages of lithium-ion battery compared with NiCad battery.

Lithium ion batteries have better discharge performance. The working voltage of lithium-ion battery is about 3.7V, while that of NiCad battery is only about 1.2V, which means that lithium-ion battery can provide better power for electrical appliances.

Lithium ion batteries have higher energy density. The capacitance of lithium-ion battery is very large. At the same capacitance, the weight and volume of NiCad battery are much larger than that of lithium-ion battery. This is also an important advantage of lithium-ion battery compared with NiCad battery, which makes the application field of lithium-ion battery more extensive.

Lithium ion battery has fast charging speed and flexible charging. Lithium ion batteries take about one to three hours to charge, while NiCad batteries take eight to ten hours. And lithium batteries can be put back into service when they are fully charged, which means that you can use a fraction of your time to maintain power for it, which NiCad batteries can't do, because it may lose the capacity of the battery or even damage the battery itself.

Lithium ion battery is pollution-free and has good effect on environmental protection. NiCad contains many harmful substances. A large number of discarded NiCad batteries may damage the local environment, and it is very difficult to dispose of them properly. Therefore, in the era of advocating environmental protection, the use of NiCad batteries should be reduced, and we should promote harmless lithium-ion batteries to take the place of NiCad batteries.

According to the above, although lithium-ion batteries and NiCad batteries are interchangeable, we should promote lithium-ion batteries to replace NiCad batteries rather than the latter to replace the former.

Can you charge a li ion battery with a NiCad charger

Please do not do this. It's a very dangerous behavior, either for you or for your battery. Because NiCad battery uses constant current charger, the voltage of charger changes greatly when charging, which may lead to battery overheating or overcharge. Lithium ion battery is sensitive to high temperature, and it is easy to degrade once it is overheated. Moreover, the overcharge resistance of lithium-ion battery is quite weak. Once overcharge occurs, the battery is easy to fail, and there may be combustion and explosion risks. Therefore, unless you want to test whether lithium-ion battery can use NiCad charger and complete safety measures, never use NiCad battery to charge lithium-ion battery.

It's also important not to combine lithium-ion batteries and NiCad batteries in the same appliance, although they are callable. Because the chemical reactions of the two kinds of batteries are different, and the chemical composition of the positive and negative electrodes of the two kinds of batteries are very different, if they are mixed, they can discharge normally, but there will be adverse chemical reactions between the two batteries, which will damage your electricity, and even cause explosion. At present, the best solution is to use lithium batteries, because lithium batteries are efficient and environmentally friendly.

How do you store li ion battery and NiCad

First, to talk about li ion battery, lithium-ion batteries should be stored in a cool and dry place without corrosive gases. The specific storage temperature is between - 20 and 35 , and the humidity should be controlled between 45% and 85%. This is because once the storage environment temperature is too high, the internal chemical balance of the battery is easy to be destroyed, and adverse chemical reactions are easy to occur, and the high environmental humidity is easy to cause the battery self discharge speed to accelerate, which is not conducive to the long-term storage of the battery and may cause short circuit. Due to the slow self discharge rate of lithium-ion batteries, it is not necessary to fully discharge lithium-ion batteries during storage. However, in order to prevent the negative effects of self discharge and passivation of active substances during long-term storage, you should charge and discharge it once every three months.

Turning to NiCad batteries, like lithium-ion batteries, they need to be stored in a cool, dry place. Moreover, because of its high self discharge rate, it will lose about 50% of the power every month, and it also has memory effect. Therefore, before storing NiCad battery, it is better to discharge it completely, put it in the original packaging of battery manufacturer or simply pack it with cloth or paper, which can effectively extend its cycle life.

Through the comparison of lithium-ion battery and NiCad battery, we can find that lithium-ion battery and NiCad battery can be used interchangeably (but can not be mixed), the charger of NiCad battery cannot be compatible with lithium-ion battery with different chemical composition, and the storage methods of lithium-ion battery and NiCad battery have similarities and differences. Moreover, it is not difficult to find that as a new type of battery, lithium-ion battery has many advantages. From its development trend, it will replace the old battery such as NiCad battery in the future.
