Lithium battery (Lithium-ion)

Lithium-ion batteries, the types we often find in electronic devices such as high-voltage flashlights, power banks, or electric cigarettes, are divided by chemical components, each with different highlights and precautions:

1.INR - Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO _ 2)

This kind of battery combines the advantages of Nickel and Manganese.

• Pros: High balance, low internal resistance, high discharge rate and reasonable capacity.

• Usage: Popular for use in devices that require high thrust, such as wireless hand tools or electric vehicles.

2.ICR - Lithium Cobalt Oxide (LiCoO _ 2)

It is a technology that focuses mainly on energy capacity.

• Pros: It has the highest capacity compared to size, but low current supply rate.

• Caution: It is chemically less stable than others. If overused or incorrectly charged, it can easily be heated. It usually requires a protective circuit.

3.IMR - Lithium Manganese Oxide (LiMn _ 2O _ 4)

Emphasis on safety and driving power.

• Highlight: It has a very stable chemical structure, good heat resistance and very strong power supply (High Discharge Rate).

• Distressed: Lower capacity than other types, not much longer to use

4.NCR - Nickel Cobalt Aluminum Oxide (LiNiCoAlO _ 2)

Similar to INR, but aluminum is used to help.

• Pros: Provides very high capacity and long life (Cycle life)

• Usage: Very popular among electric cars (such as Tesla) and high-quality power banks.

5.IFR - Lithium Iron Phosphate (LiFePO _ 4)

Also known as LiFePO4.

• Pros: The safest, and longest-lasting (thousands of cycles charged), the voltage is relatively constant throughout use.

• Difference: It has a lower voltage than its companion (Nominal Voltage is 3.2 V), so it requires a specialized charger. It cannot be combined with a conventional lithium charger that is 3.7 V. Additional instructions:

• Option: If you want to use a heavy fire-eating device (such as an electric drill), choose INR or IMR, but if you want it to be activated for a long time (such as a portable flashlight), choose ICR or NCR.

• Safety: For 3.7 V family batteries (INR, ICR, IMR, NCR), if there is no built-in protective circuit, do not use until the voltage is below 2.5 V, because it will cause permanent deterioration of the battery.
