do you know what rechargeable lithium batteries are?

Unlike standard batteries, rechargeable batteries can be used and reused multiple times before they are discarded.
They are able to repeatedly charge and discharge using charger devices that pass through the current of the battery.
There are electrolytic chemicals with high active life in rechargeable batteries.
These chemicals allow rechargeable batteries to be activated and can be used even after \"running out\" a few times.
The use of rechargeable batteries is not unlimited;
When the active life of the electrolytic chemical is completely exhausted, the battery cannot be recharged.
The type of rechargeable battery varies depending on the electrolytic chemicals used.
These include nickel metal hydrogen (NiMH)
Nickel and cadmium (Ni Cd)
Lead-acid and lithium-ion rechargeable batteries.
Of all types, lithium-ion batteries have the highest energy density rate.
This refers to the energy stored in the battery, expressed as a function of weight or volume.
In contrast, the battery voltage of the lithium-ion battery is 3.
6 V, while the battery voltage of NiMh and lead-acid batteries is usually 1. 2 volts and 2.
2 volts respectively.
Therefore, among all other types of rechargeable batteries, the cost of lithium batteries is the highest.
Lithium battery is ideal for long use
The use of terms is not only because of their high energy density, but also because of their low self-feeding rate. discharge.
Therefore, even if the battery is not used for a long time, it will not risk death.
Since the year of manufacture, the lithium-ion battery has lost only 5%-
10% of the annual storage capacity.
That\'s why lithium-ion batteries are ideal for emergency devices such as laptops, mobile phones, digital SLR cameras, especially smoke alarms and emergency flashlights.
According to the companies that produce these batteries, commercial lithium-ion batteries are different from each other based on the different lithium compound cathode used. Li-
Sony\'s Ion battery uses lithium cobalt oxide cathode and graphite anode. Li-
Manganese spinel is a cathode used by other companies such as LG, NEC and Samsung.
However, due to the high volatile electrolytic combination used in lithium-ion batteries, there is a high risk of explosion when they are short-circuited or overheated.
In the case of rechargeable lithium-ion batteries, prolonged exposure to direct sunlight can be very dangerous.
It is very important that these batteries are purchased only from very reliable manufacturers with very high quality control standards to ensure that they are safe and reliable.
