What is the difference between rechargeable batteries and ordinary batteries?
As the name implies, rechargeable batteries can be used repeatedly and have a long cycle life. They may be recharged and used. Some rechargeable batteries have a higher load capacity than most disposable batteries; rechargeable batteries mainly include nickel-metal hydride batteries and nickel-cadmium batteries. Lithium-ion batteries, lead-acid batteries, etc.;
Ordinary batteries often refer to "disposable" batteries that cannot be recharged and used repeatedly, because they can no longer be recharged after their power is exhausted. Ordinary batteries mainly include primary carbon batteries, primary alkaline batteries, button zinc silver batteries, button lithium manganese batteries, button zinc manganese batteries, primary lithium manganese batteries, etc.;
There are so many kinds of batteries, what is the difference between rechargeable batteries and ordinary batteries?
1. Rechargeable batteries have a self-discharge effect, and their power retention capacity is not as good as that of ordinary batteries. Therefore, it is recommended that rechargeable batteries be fully charged every 60 days when they are not used for a long time; ordinary batteries are relatively small in self-discharge;
2. The rechargeable battery is not resistant to storage, so the performance of the rechargeable battery will be greatly reduced if it is not used for a long time, and it cannot be used. Ordinary batteries are more resistant to storage,
3. Rechargeable batteries need to be used with professional chargers. The initial purchase cost is relatively high, but it is more cost-effective in the long run; ordinary batteries can be used, which is relatively convenient;
4. Rechargeable batteries can be recycled for many times, which is relatively more economical and environmentally friendly, and has less environmental pollution than disposable batteries;
5. There are different active materials on the positive plate of the rechargeable battery, the active material on the negative plate is spongy pure lead, and the electrolyte is a sulfuric acid solution with a certain concentration.
6. The negative electrode active material of ordinary batteries is composed of a reducing agent that has a relatively negative potential and is stable in the electrolyte, such as active metals such as zinc, cadmium, and lead, and hydrogen or hydrocarbons. The positive electrode active material is composed of an oxidant that has a positive potential and is stable in the electrolyte.
Seven, rechargeable batteries have a larger capacity in batteries of the same size, especially lithium-ion batteries are now widely used in products such as notebook computers, mobile phones, electric vehicles and new energy vehicles.
8. Ordinary battery has stable voltage, stable current, stable power supply for a long time, current with little influence from the outside, and the battery has a simple structure, low cost, convenient to carry, easy to charge and discharge, and is not affected by external climate and temperature , The performance is stable and reliable.
