Hi Mi-Fans

No matter which smart device you are using it must have a battery. The battery that mainly used, are of two types: Lithium-Ion and Lithium Polymer.

Let's start knowing about the both of the types!

Lithium-ion Battery:

A lithium-ion battery or Li-ion battery is a type of rechargeable battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging. Li-ion batteries use an intercalated lithium compound as one electrode material, compared to the metallic lithium used in a non-rechargeable lithium battery.


  • Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim.
  • Lithium-ion cells cause little harm when disposed of.
  • It is fragile and requires a protection circuit to maintain safe operation.
  • Lithium-ion packs are known to have served for five years in some applications.
  • High energy density – the potential for yet higher capacities.
  • Does not need prolonged priming when new. One regular charge is all that’s needed.
  • Relatively low self-discharge – self-discharge is less than half that of nickel-based batteries.
  • Low Maintenance – no periodic discharge is needed; there is no memory.
  • Specialty cells can provide very high current to applications such as power tools.


  • Li-ion battery is susceptible to the downside of too much heat caused by overheating of the device or overcharging. Heat causes the cells or packs of this battery to degrade faster than they normally would.
  • Li-ion battery will naturally degrade as soon as they live the factory. This means that it is not completely durable despite longer charge-discharge lifecycle because of this normal degradation that transpires whether consumers use them or not.
  • Li-ion battery has low self-discharge. The general integrity of this battery remains intact even if partially discharged.

Lithium-Polymer Battery:

A lithium polymer battery, or more correctly lithium-ion polymer battery (abbreviated as LiPo, LIP, Li-poly,lithium-poly and others), is a rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid one. High conductivity semisolid (gel) polymers form this electrolyte. These batteries provide a higher specific energy than other lithium-battery types and are being used in applications, where weight is a critical feature - like tablet computers, cellular telephone handsets or radio-controlled aircraft.


  • Very low profile – batteries resembling the profile of a credit card are feasible.
  • Flexible form factor – manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
  • Lightweight – gelled electrolytes enable simplified packaging by eliminating the metal shell
  • Improved safety – more resistant to overcharge; less chance for electrolyte leakage.


  • Compared with lithium-ion battery energy density and cycle number are falling
  • There is no standard shape, most battery manufacturing for high volume consumer market
  • Depending on chemistry can be more volatile than traditional batteries
  • More costly than Li-Ion Battery.

Now you have already the basic Idea about both types.
