What is a Lithium-ion Battery?

lithium-ion battery or Li-ion battery is an advanced battery technology that uses lithium ions as a key component of its chemistry, is a type of rechargeable battery composed of cells in which lithium ions move from the negative electrode through an electrolyte to the positive electrode during discharge and back when charging.
Li-ion cells use an intercalated lithium compound as the material at the positive electrode and typically graphite at the negative electrode.

What are advantages of Li-ion Battery?

  • High Energy Density:The high energy density is one of the chief advantages of lithium ion battery technology. With electronic equipment such as mobile phones needing to operate longer between charges while still consuming more power, there is always a need to batteries with a much higher energy density.
  • NMemory Effect: Lithium-ion batteries have no memory effect and can be recharged at any time.
  • Low Maintenance: Do not require and maintenance to ensure their performance.
  •  Low Self-Discharge Rate: The rate of self-discharge is much lower than that of other rechargeable cells such as Ni-Cad and NiMH forms.
So the best portable chargers for phones all use lithium-ion rechargeable batteries.

How to choose your perfect battery pack ?
  • Capacity
You can consider from below points:
  • Which devices do you plan to use with it?
  • How many devices do you plan to use with it simultaneously?
  • How long you’re going to be away from an outlet and will need it?
Then you can check the power bank for mAh, and compare it to what you really need, whether that’s a small 3,000 mAh battery (great for phones), or a robust 20,000 mAh model (powerful enough for laptops).
  • Size
The size of the battery is about the power inside. Most batteries will feature a number on the front that tells you the number of mAh.
Common sizes range from 2000mAh up to 10,000 or even 12,000 mAh.
Bigger numbers mean more power, which means more recharges for your smartphone, or charging for bigger devices that need more power, like a tablet.
